Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-dimensional game device that attacks a target in a virtual three-dimensional space.

[0002]

2. Description of the Related Art FIG. 29 (a) shows an example of a game image of a battle game expressed by a conventional game device.

In the conventional game machine, as shown in FIG. 29 (a), the player plays his own ship 530,
A battle game was played by operating the My Ship 530 while watching the composite image of the enemy aircraft 532 viewed from above.
In the game device of such a system, myship 530,
The enemy plane 532 and the like are game fields 5 configured in two dimensions.
I could only move within 36. Moreover, the player can only see the composite image viewed from above, that is, the composite image from the predetermined viewpoint position and viewpoint direction.

However, in the battles that take place in the real world,
As shown in FIG. 6B, the attack by the enemy aircraft 532 is performed from all directions of 360 degrees in the three-dimensional space. on the other hand,
The myship 530 controlled by the player can also freely move around in the three-dimensional space.
While defending against the attacks of enemies attacking from 0 degrees in all directions, it is possible to attack the enemies from 360 degrees in all directions. And in this way, attack in 360 degrees in all directions.
When performing defense, the viewpoint position and viewpoint direction of the player are different each time the direction is changed, and thus the view image that the player can see is also different.

As described above, the game space represented by the conventional game device is far from the world experienced by the player in the battle performed in the real world. Also, the game image synthesized by the conventional game device is completely different from the view image that the player can see in the battle performed in the real world. For this reason, it was not possible to enhance the sense of reality, tension, and fun of the game.

[0006]

In order to solve such a problem of the conventional game device, the present inventor can freely move around in a virtual three-dimensional space by a moving body operated by a player to attack an enemy.

Therefore, when a large number of complicated obstacles or the like are arranged in the game field, the player can hardly aim at the enemy due to the obstacles or the like. As a result, there is a problem in that the settings of maps and the like formed in the game field are also subject to large restrictions.

Further, in comparison with a conventional game in which the Myship 530 and the enemy machine 532 can only move within a two-dimensional range, such a three-dimensional game device protects an enemy attacking from 360 degrees in all directions. You must attack the enemy in all directions of 360 degrees. When attacking or defending, it is necessary to do this while checking the enemy information such as the remaining amount of the enemy shield and the number of missiles of the enemy, or the information of the own aircraft. Therefore, it is necessary to instantaneously perform such information without moving the line of sight.

【Example】

1. Outline of Game First, an example of a three-dimensional game realized by the present three-dimensional game device will be briefly described.

According to the present three-dimensional game device, a virtual three-dimensional space is formed by a preset game program, and the formed virtual three-dimensional space can be freely moved around by the moving body operated by the player. Can provide space.

The three-dimensional game realized by the present three-dimensional game device is a future tank game spread in a near future city where various races are gathered. In this futuristic tank game, fighters who have gathered for huge prize money decide the champion in a death match game format in the game field surrounded by a square that cannot be escaped. Each fighter competes for a champion with its own future tank. The player then participates in the game as one of these fighters.

FIG. 2 shows an external view of the present three-dimensional game device. As shown in the figure, the player 302 operates the left and right analog levers 12 and 14 which are operation sections to perform CR.
The moving body imaged at T10, that is, the future tank 20 will be operated. That is, the player 302 can freely move back and forth, left and right in the game field 60 set in the virtual three-dimensional space by operating the future tank 20. Further, the analog levers 12 and 14 are provided with machine guns that can be fired indefinitely and missile triggers 16 and 18 that are powerful weapons with a limited number. Further, as shown in FIG. 2, the aim 40 is projected on the CRT 10, and the player 302 uses this aim 40 to attack the enemy. Further, the CRT 10 displays an enemy position detection radar 50 that detects the position of an enemy, which is a target, so that the player 302 can know the enemy position 52 with respect to the own-machine position 51.

An overall view of the game field 60 is shown in FIG. As shown in the figure, in the game field 60, various terrains formed in three dimensions and set by the game program are formed. That is, first
The four sides of the game field 60 are surrounded by walls 62 so that each fighter cannot escape. A first plateau 64 is provided on the inner circumference of the wall 62. The zero zone 66 is surrounded by the first plateau 64, and slopes 68, 70, 72, 74 are provided between them. Furthermore, in the zero zone 66, the second and third plateaus 76,
78 is also provided, and obstacles 80, 82 are also provided. As described above, the game field 60 in this three-dimensional game is the same as the conventional game field 60 shown in FIGS.
Unlike the game fields 536 and 538, which are composed of dimensions, they are composed of three-dimensional terrain. Therefore, it is possible to form a game space full of reality that has never existed before.

The future tank 20 operated by the player 302 and the enemy future tank 22 operated by the enemy fighter face each other on the zero zone 66. In FIG. 3, the future tank 2
The second and third plateaus 7 are located between 0 and the enemy future tank 22.
Since the players 6 and 78 are present, the player 302
The enemy future tank 22 cannot be seen by T10. Therefore, the player 302 first finds the enemy position 52 by the enemy position detecting radar 50 described above. Then, the future tank 20 is steered by the analog levers 12 and 14 to get over the second plateau 76, approach the enemy, and attack the enemy.

FIG. 4 shows a pseudo three-dimensional image displayed on the CRT 10 when the own future tank 20 approaches the enemy future tank 22 in this way. Here, the shield display section 54 displays the shield amounts of the own aircraft and the enemy future tank 22. At present, the shield amount (defense) of the player's own aircraft greatly exceeds the shield amount of the enemy future tank 22. Therefore, it is an opportunity for the player 302 to attack, and conversely, the enemy future tank 22 must avoid this critical situation and find an item that restores the shield amount.

In this case, the player 302 aims at the enemy future tank 22 while looking at the aim 40 to attack. Here, the sight 40 is divided into a machine gun sight 41 and a missile sight 42. Moreover, the missile remaining number 43 is projected on the upper part of the sight. Furthermore, a marker 30 is attached to the enemy future tank 22.

The future tank 20 is equipped with a machine gun and a missile as weapons, and the machine gun is aimed by the machine gun aiming section 41. That is, if the machine gun is fired at the moment when the cross-shaped portion of the aiming portion 41 coincides with the enemy future tank 22, the enemy can hit the machine gun.

On the other hand, the missile is aimed by the missile aiming section 42. However, in this case, the own future tank 20 is located above the zero zone 66, and the enemy future tank 2
Since No. 2 is located on the first plateau 64, there is a difference in height between the two. Therefore, the enemy future tank 22 is not located on the extension of the barrel of the future tank 20, and it is difficult to attack with the machine gun described above. In addition, it is difficult for missiles to hit with a missile that can only go straight, like a machine gun. So, book 3
In the three-dimensional game device, the missile has a tracking function. As a result, the enemy future tank 22 becomes the own future tank 20.
You can hit missiles without being on the extension of the gun barrel. Then, the missile aiming section 42 indicates a standard of a range that can be tracked by the missile.

The missile remaining number 43 displays the remaining number of missiles of its own machine, and in the figure, the remaining number of missiles is three. In this case, since the player 302 is now following an attacking opportunity and chasing the enemy future tank 22, the line of sight of the player 302 is fixed near the sight 40, and for example, the missile may be launched even though there is no remaining missile. There is. Therefore, in the three-dimensional game device, in order to prevent such a situation, the missile remaining number 43 is set at a position where the line of sight of the player 302 is concentrated,
That is, it is arranged near the periphery of the sight 40.

On the other hand, a marker 30 is attached to the enemy future tank 22. This marker 30 shows that the enemy future tank 22
When the player 302 is located within the visual field range (the image display range), it is always stuck. Therefore, the player 302 confirms the position of the enemy by the enemy position detection radar-50 when the enemy future tank 22 is out of the visual field range,
When in the visual field range, the position of the enemy can be confirmed by the marker 30.

The marker 30 usually has a square shape, but in the figure, it is transformed into a rhombus. And
The diamond shape indicates that the enemy future tank 22 has entered the tracking range. That is, while the missile aiming unit 42 is a guide for the tracking range, the deformation of the marker 30 into a diamond shape results in the enemy being within the tracking range as a result of calculating various situations such as the distance to the enemy. It indicates that there is a more accurate display. The marker 30 is currently blinking. This blinking indicates that the shield amount of the enemy future tank 22 is extremely small as shown in the shield display portion 54. Therefore, the player 30
For No. 2, it is possible to confirm that there is an attack opportunity now without shifting the line of sight to the shield display portion 54. As described above, in the present three-dimensional game device, the marker 30 is used to display the target state information so that the player 302 can easily attack the target.

The above description is for the case where there is one player playing the game, as shown in FIG. When the player plays the game alone, the computer is in charge of the fighter who drives the enemy future tank 22. On the other hand, in FIG.
An external view of the present three-dimensional game device when two players play a match is shown. In this case, the player 302 uses C
While watching the RT10, pilot the future tank 20, and player 3
03 will operate the enemy future tank 22 while watching the CRT 11. Then, the CRT 10 displays a pseudo three-dimensional image viewed from the direction of the future tank 20.
In 1 is displayed a pseudo three-dimensional image seen from the direction of the enemy future tank 22. In this way, two players play a game under different geographical conditions while viewing pseudo three-dimensional images from different viewpoints in one virtual three-dimensional space. In addition, in FIG.
Although shown only for a human player, the present invention is not limited to this, and is naturally applicable to a case where a game is played by three or more players. 2. Description of Entire Device FIG. 1 shows a block diagram of an embodiment of a three-dimensional game device according to the present invention.

As shown in FIG. 1, in this embodiment, the operation section 140 for the player to input an operation signal, and the game space calculation section 1 for setting the game space by a predetermined game program.
00, a player's viewpoint position, an image synthesizing unit 200 that forms a pseudo three-dimensional image in the viewpoint direction, and a CRT 10 that outputs this pseudo three-dimensional image.
When the present three-dimensional game device is applied to a driving game, for example, a steering wheel, a gear or the like for driving a sports car is connected to the operation unit 140, and an operation signal is input by this. When applied to a shooting game such as the future tank battle, the analog levers 12 and 14 for operating the future tank and the triggers 16 and 18 for launching machine guns, missiles, etc.
Etc. are connected.

The game space calculation section 100 is constituted by at least the object information storage section 104, the marker setting section 150, and the aim setting section 170. Here, the object information storage unit 104 stores object information that is position and direction information of a three-dimensional object that forms a virtual three-dimensional space, and other attribute information. In addition, the marker setting unit 150 is set so that the above-described marker 30 representing the position of the enemy future tank 22 that is the target is displayed on the pseudo three-dimensional image that is image-synthesized by the image synthesizing unit 200. Similarly, in the aiming setting unit 170,
The setting is performed so that the sight 40 for aiming at the enemy future tank 22 is displayed on the pseudo three-dimensional image.

In the image synthesizing unit 200, a pseudo three-dimensional image that can be seen from the arbitrary viewpoint position and direction of the player 302 in the virtual three-dimensional space, that is, the CRT 10 in FIG.
The pseudo three-dimensional image shown in FIG. For this reason, the image composition unit 200 uses the three-dimensional image information storage unit 20.
4 and the image calculation unit 202.

The three-dimensional image information storage unit 204 stores a three-dimensional image of a three-dimensional object. here,
The three-dimensional object is a moving body such as the future tank 20 or the enemy future tank 22 shown in FIG. 4, the wall 62 shown in FIG.
Second and third plateaus 64, 76, 78, obstacles 80, 82
It refers to all objects that form the game space set in the virtual three-dimensional space, such as topography. As shown in FIG. 4, this three-dimensional object is expressed as a set of polygons 90 to 95, etc., and information such as the coordinates of each vertex of this polygon is 3
It is stored in the three-dimensional image information storage unit 204 as three-dimensional image information.

In the three-dimensional game device shown in FIG. 1, first,
A predetermined game space is set in the game space calculation unit 100 based on an operation signal from the operation unit 140 and a preset game program. That is, the game space calculation unit 100 determines the positions, or positions and directions, of all three-dimensional objects forming the game space in accordance with the operation signal and the game program, and stores them as object information in the object information storage unit 104. . Next, the image composition unit 200 arranges the three-dimensional image information stored in the three-dimensional image information storage unit 204 in the virtual three-dimensional space in the direction specified at the position specified by the object information. In the image calculation unit 202, a pseudo three-dimensional image viewed from the viewpoint position and the viewpoint direction of the player is image-synthesized from the arranged three-dimensional image information, and the CRT 10 outputs the image.

Then, in the three-dimensional game apparatus shown in FIG. 1, the marker setting section 150 and the aim setting section 170 further set the aiming system including the marker 30 and the aiming 40. As a result, the player 30
2 can attack the target while looking at the marker 30 and the aim 40 displayed on the pseudo three-dimensional image.

FIG. 9 is a block diagram showing the embodiment of the three-dimensional game apparatus in more detail.

In the embodiment shown in detail in FIG. 9, the game space computing section 100 is further configured to include a central processing section 102, a terrain information storage section 106, and an object information changing section 108. This makes it possible to form a game space in which the terrain information is reflected. Here, the central processing unit 102 controls the entire three-dimensional game device. Further, a predetermined game program is stored in the storage unit provided in the central processing unit 102. Further, the terrain information storage unit 106 stores the terrain information of the game field 60 formed by the above-described three-dimensional terrain, for example, as height data. Also, the object information changing unit 108
Then, an operation is performed in which the object information stored in the object information storage unit 104 is changed at any time based on the terrain information stored in the terrain information storage unit 106.

In the three-dimensional game device shown in detail in FIG. 9, the image synthesizing section 200 further includes a frame image forming section 180, and the image calculation section 202 includes
The image supply unit 212 and the image forming unit 240 are included.

The frame image forming section 180 forms an image of the marker 30 and the aim 40 set by the marker setting section 150 and the aim setting section 170 as a two-dimensional frame image.

The image supply unit 212 includes a processing unit 214 that controls the entire image synthesizing unit 200, a coordinate conversion unit 216 that performs a three-dimensional calculation process on image information such as polygon vertex coordinates, and a clipping processing unit 218. The perspective conversion unit 220 and the sorting processing unit 222 are included.

In the image forming section 240, the image supply section 212
The image information of all the dots in the polygon is calculated from the image information such as the vertex coordinates of the polygon which has been subjected to the three-dimensional calculation processing in (3), and thereby the pseudo three-dimensional image is image-synthesized. Further, in the image forming unit 240, the two-dimensional frame image formed by the above-mentioned two-dimensional frame image forming unit 180 is further image-synthesized into this pseudo three-dimensional image,
As a result, the pseudo 3 in which the marker 30 and the sight 40 are displayed
The three-dimensional image is output to the CRT 10.

Next, the operation of the entire 3D game apparatus will be described.

First, at the same time as the game starts, the central processing unit 102 stores the object information, which is the position and direction information of all three-dimensional objects arranged in the virtual three-dimensional space, according to the game program, in the object information storage unit 104. To memorize. However, if a part of the object information storage unit 104 is a non-volatile memory and the initial value of the object information is stored in advance, such an operation is not necessary.

The object information stored in the object information storage unit 104 is stored in the format shown in FIG. 6, for example. In the figure, the index (0
N are serial numbers representing each three-dimensional object. For example, index 0 is a future tank 20, index 1 is an enemy future tank 22, index 2 is a wall 62.
The index 3 is a serial number representing a three-dimensional object forming the obstacle 80. This gives, for example,
The position information and the direction (tilt) information of the future tank 20 in the virtual three-dimensional space are (X0, Y0, Z0) and (θ0,
φ0, ρ0). As a result, the position and direction in which the future tank 20 is arranged are determined. Similarly, the position and direction information of the three-dimensional objects such as the enemy future tank 22 and the obstacle 80 are also set, whereby the position and direction information of all the three-dimensional objects forming the game space in the virtual three-dimensional space are obtained. It will be decided.

In the case of a large three-dimensional object such as the future tank 20, this is divided into parts such as the cockpit, the left driving part, the right driving part, and the barrel, and each of these parts is divided into parts. May be considered as a three-dimensional object, and the index may be assigned to this. In this way, these parts, for example, the left drive unit, the right drive unit, the barrel, etc. can be independently moved, and the future tank 20 can be drawn with more realistic movement.

The terrain information storage unit 106 stores the terrain information of the game field 60 shown in FIG. 3 as height information, for example. The object information changing unit 108
By reading this topographical information, it is possible to change the position and direction information of the three-dimensional object stored in the object information storage unit 104. That is, for example, the position and direction information (X0,
The values of Y0, Z0, θ0, φ0, ρ0) are changed to change the inclination and the like of the future tank 20. This makes it possible to form a game space that reflects the terrain information.

Next, the marker setting unit 150 and the aiming setting unit 170 set the display of the marker 30 and the aiming 40. That is, the marker 30 and the aim 40 are set in what form and at which position. The setting information of the marker 30 and the sight 40 is shown in FIG.
As shown in, the image is input to the frame image forming unit 180. The frame image forming unit 180 forms a two-dimensional frame image based on this setting information and the like. The formed two-dimensional frame image is superimposed on the pseudo three-dimensional image by the image forming unit 240, whereby the marker 30 and the sight 40 are formed.
Will be displayed on the pseudo three-dimensional image. The details of the setting of the marker 30 and the sight 40 will be described later.

Next, the operation of the image synthesizing section 200 will be described.

First, the processing unit 214 reads the position and direction information of the three-dimensional object from the object information storage unit 104 using the index as an address. Similarly, the processing unit 214 reads the three-dimensional image information of the three-dimensional object from the three-dimensional image information storage unit 204 using the index as an address. For example, when the index is 0, the position and direction information of the future tank 20 (X0, Y0, Z0, θ0, φ)
0, ρ 0) is read from the object information storage unit 104, and the three-dimensional image information representing the future tank 20 as a set of polygons is read from the three-dimensional image information storage unit 204.

The processing unit 214 sequentially reads the indexes in this way and converts these information into a data format as shown in FIG.

FIG. 7A shows an overall view of this data format. As shown in the figure, the data to be processed is configured such that the frame data is at the head and the object data of all three-dimensional objects displayed in this frame are continuous. Then, after this object data, polygon data of polygons forming the three-dimensional object is further arranged.

Here, the frame data refers to data formed by parameters that change for each frame, and is common to all three-dimensional objects in one frame. The viewpoint position, viewpoint direction, and viewing angle of the player. It is composed of data such as information, monitor angle / size information, and light source information. These data are set for each frame. For example, when a window or the like is formed on the display screen, different frame data is set for each window. By this, on the display screen, for example, a rearview mirror,
It is possible to form a screen or the like of the future tank 20 viewed from above.

The object data refers to data formed by parameters that change for each three-dimensional object, and position information in units of three-dimensional objects,
It is composed of data such as direction information. This is data having almost the same content as the above-mentioned object information.

Further, the polygon data means data formed by image information of polygons and the like, and as shown in FIG. 7B, a header, vertex coordinates X0, Y0, Z0 to X3,
It is composed of other attached data such as Y3 and Z3.

The coordinate calculation unit 216 reads out the data in the above formats and performs various calculation processes on the coordinates of each vertex. The calculation process will be described below with reference to FIG.

Taking the future tank game as an example, FIG.
As shown in, three-dimensional objects 300, 332, and 334 representing future tanks, enemy future tanks, buildings, obstacles,
It is arranged in a virtual three-dimensional space represented by the world coordinate system (XW, YW, ZW). After that, the image information representing these three-dimensional objects is coordinate-converted into a viewpoint coordinate system (Xv, Yv, Zv) with the viewpoint of the player 302 as a reference.

Next, the clipping processing unit 218 performs image processing called so-called clipping processing. Here, the clipping processing is image information outside the field of view of the player 302 (or outside the field of view of the window opened in the three-dimensional space), that is, the front / rear / right / down / left / up clipping planes 340 and 342. 344, 3
This is image processing for removing image information outside an area (hereinafter referred to as display area 2) surrounded by 46, 348, and 350. That is, the image information required by the present apparatus for the subsequent processing is only the image information within the visual field of the player 302. Therefore, if the other information is removed in advance by the clipping process, the load of the subsequent process can be significantly reduced.

Next, in the perspective conversion unit 220, the display area 2
Only the object inside is subjected to perspective transformation into the coordinate system (XS, YS) of the screen 306, and the data is output to the sorting processing unit 222 at the next stage.

In the sorting processing section 222, the order of processing in the image forming section 240 in the next stage is determined, and the image data of the polygon is output according to the order.

In the image forming section 240, the image supply section 212
The image information of all the dots in the polygon is calculated from the data such as the vertex coordinates of the polygon which has been subjected to the three-dimensional calculation processing in (3). As a calculation method in this case, the contour line of the polygon is obtained from the vertex coordinates of the polygon, the contour point pair which is the intersection of this contour line and the scanning line is obtained, and the line formed by this contour point pair is given a predetermined color. You may use the method of making it correspond to data etc. In addition, the image information of all the dots in each polygon is stored in advance in a ROM or the like as texture information, and the texture coordinates given to each vertex of the polygon are used as an address, which is read and pasted. May be.

Finally, the pseudo three-dimensional image formed by the image forming section 340 is output from the CRT 10. 3. Setting of Marker and Setting of Aim Next, the setting of the marker 30 and the aim 40 performed by the game space calculation unit 100 will be described in detail. (1) Marker Setting First, the setting of the marker 30 performed by the three-dimensional game device of the embodiment shown in FIG. 10 will be described in detail.

As shown in FIG. 10, the central processing unit 102 of this three-dimensional game apparatus includes a display area determination unit 110. The display area determination unit 110 determines whether or not the target, for example, the enemy future tank 22 is present in the display area 2 shown in FIG.

As shown in the figure, the marker setting unit 1
50 is a marker display determination unit 152 and a marker position setting unit 1
54 is included. This marker display determination unit 1
At 52, according to the determination result of the display area determination unit 110, it is determined whether or not the marker 30 is displayed on the pseudo three-dimensional image. In addition, the marker position setting unit 154
Then, the marker display determination unit 152 calculates the display position of the marker 30 determined to be displayed.

Next, the operation of the three-dimensional game device shown in FIG. 10 will be described.

First, the central processing unit 102 reads at least the position information from the object information storage unit 104 out of the object information of the enemy future tank 22. Next, in the display area determination unit 110, based on this position information,
It is determined whether or not this enemy future tank 22 exists in the display area 2. In other words, the plane equations of the clipping planes 340 to 350 that form the display area 2 are added to the enemy future tank 22.
If the position information V1 (X1, Y1, Z1) is assigned and it is determined that all the clipping planes are within the display area, the enemy future tank 22 is determined to be within the display area 2. It Specifically, for example, the plane equation of the clipping plane 340 is expressed by h (V) = aX + bY + cZ + d
When h (V1) = aX1 + bY1 + cZ1 + d is calculated, and when h (Vn) ≦ 0, Vn is judged to be in the display area 2 of the clipping plane 340,
When h (Vn)> 0, Vn is judged to be outside the display area 2. Then, this calculation is performed on all the clipping planes 340 to 350. However, for example, the clipping planes 340 and 342 may be omitted.

When it is determined that the enemy future tank 22 is in the display area 2, the marker display determination unit 152 determines to display the marker 30 on the pseudo three-dimensional image, and the form of the marker 30 to be displayed. Is also determined. Then, the position information of the enemy future tank 22, the information regarding the form of the marker 30, and other necessary information are output to the marker position setting unit 154.

Next, the marker position setting unit 154 determines the set position of the marker 30 on the pseudo three-dimensional image from the position information of the enemy future tank 22, the position information of the screen 306, and the viewpoint position information of the player 302. It is determined. Specifically, as shown in FIG. 11A, the marker 30 is set at a position C which is substantially the intersection point between the line connecting the viewpoint position A of the player 302 and the position B of the enemy future tank 22 and the screen 306. Is set to. By setting this position, even if the viewpoint position and the viewpoint direction of the player 302 change, the marker 30 displayed on the pseudo three-dimensional image is always kept in the enemy future tank 2
It is possible to stick it to position 2.

The setting information of the marker 30, which is set as described above, that is, the form information and the position information of the marker 30, are
It is output to the frame image forming unit 180. Then, a two-dimensional frame image is formed, and the marker 30 is displayed by superimposing it on the pseudo three-dimensional image.

FIG. 12A shows an example of a pseudo three-dimensional image on which the marker 30 is displayed in this way. In the figure, the future tank 20 of the player's own machine is catching the enemy future tank 22 near the wall 62. The enemy future tank 22 has escaped in order to avoid the attack because the shield amount is almost left as shown in the shield display portion 54. Even in this case, since the marker 30 is attached to the enemy future tank 22, the player can easily catch the enemy. FIG. 12B shows a scene when the enemy future tank 22 has subsequently escaped. In this case, the enemy future tank 22 is no longer in the display area 2, so the marker 30 is not displayed.

13 (A) and 13 (B) show the most characteristic scenes showing the effectiveness of the marker setting according to this embodiment. In the same figure (A), the enemy future tank 22 is trying to escape behind the obstacle 82 in order to avoid the attack from the future tank 20. In this case, since the enemy future tank 22 exists in the display area 2, the marker 30 is attached to the enemy future tank 22.

In the same figure (B), after that, the enemy future tank 22
A scene in which the vehicle has been escaped behind the obstacle 82 is shown in FIG. Even when the view of the enemy future tank 22 is blocked by the obstacle 82, the marker 30 is displayed at a position corresponding to the position of the enemy future tank 22 as shown in FIG. There is. As described above, according to the marker setting according to the configuration of the present embodiment, the marker 30 is always displayed at the position corresponding to the position of the target even if the view of the target is blocked. Therefore, the player can grasp the position of the enemy even after the enemy escapes, and can easily track the enemy. Further, in this embodiment, the obstacle 82 is configured to be destructible by the missile,
The player can destroy the obstacle 82 with the missile, and can mount an attack on the enemy again after the enemy can see the obstacle 82.

Now, as another method for finding an enemy when the enemy escapes in this way, it is conceivable that the enemy position detecting radar 50 shown in FIG. 13 is used for tracking. However, the enemy position detecting radar 50 can only grasp the approximate distance and direction to the enemy. Therefore, like the marker 30, it is difficult to know whether or not the enemy is behind the obstacle 82. Further, in such an enemy position detecting radar 50, in order to confirm this radar, it is necessary to move the line of sight from the sight 40 once. Then, after moving the line of sight, the relationship between the own-vehicle position 51 and the enemy position 52 must be grasped by looking at the radar. However, in such a state of catching the enemy, normally, the player has no room to shift the line of sight to the radar in this way and further grasp the relationship between the own-machine position 51 and the enemy position 52. It is normal. Therefore, in such a case, the enemy position radar 50 is useless.

On the other hand, with the marker 30 shown in FIG. 13 (B), first of all, in order to grasp the enemy position, it is only necessary to find out the marker 30 on the screen, so it is very easy to grasp the enemy position. Is. Further, it is possible to recognize not only the rough position and direction of the enemy but also that the enemy is hidden by the obstacle 82. Further, normally, in such a scene where the enemy is chased, the sight 40 of the player's aircraft and the enemy future tank 22 are usually at substantially the same position. Then, according to this embodiment, the marker 30 is attached to the enemy future tank 22. Therefore, the player can simultaneously see the sight 40 of the own aircraft, the enemy future tank 22, and the marker 30 on the same line of sight. As a result, it is not necessary to shift the line of sight as in the case where the enemy position radar 50 is used. From the above, it is understood that the aiming system according to the present embodiment is extremely excellent and is the most suitable as the aiming system in such a three-dimensional game space.

In FIGS. 14A and 14B, the view of the own machine is
A scene blocked by fog 24 is shown. Even when the field of view is blocked by the fog 24 in this way, according to the configuration of the present embodiment, the marker 30 is always attached to the enemy as shown in FIG. Then, FIG. 3B shows a scene in which the enemy future tank 22 comes out of the fog 24. Since the marker 30 is stuck to the player even when the enemy cannot be seen as shown in FIG. 11A, even if the enemy future tank 22 suddenly comes out as shown in FIG. It is possible to set the aim 40 at the enemy.

14 (A) and 14 (B) show the case where the field of view is blocked by the fog 24, for example, in the darkness of night,
Even when the view is blocked by snow, rain, or the like, the marker 30 is always attached to the enemy as in the case shown in the figure, so that the player can easily aim the aim 40 at the enemy.

Incidentally, FIG. 15 shows a block diagram of an embodiment in the case of representing fog, night darkness, etc. in the virtual three-dimensional space as described above. This will be briefly described below.

The embodiment shown in FIG. 15 is different from the embodiment shown in FIG. 9 in that a visual field setting unit 190, a palette number changing unit 192, and a color code changing unit 194 are newly added. Further, in FIG.
The color pallet portion 196 built in 0 is also shown.

The visibility situation setting unit 190 sets the visibility situation of the game field in which the game is played each time the game is started. That is, if the game surface selected by the player is a foggy surface, the fog game field is changed to
If it is a night scene, the game field at night is set.

As shown in FIG. 16, the color palette unit 196 contains, for example, eight (0 to 7) color palettes. As shown in the figure, the palette number is an address that specifies which of the eight color palettes is selected, and the color number is an address that specifies which color code of the color palette is selected. is there. The color palette unit 196 can output an 8-bit color code for each of R, G, and B by designating these addresses.

In the pallet number changing unit 192, according to the visibility situation setting data from the visibility situation setting unit 190,
The palette number used for the polygons forming the pseudo three-dimensional image is set and changed for each polygon. Specifically, the pallet number used for the polygon is set according to the distance between itself and the polygon to be processed.

The color code changing unit 194 changes the color code in each color palette in response to the visibility situation setting data from the visibility situation setting unit 190 at the start of the game. That is, if the visibility situation of the fog is set,
The color code of the color palette is changed so that it approaches white as the distance from the player increases.

Next, the operation of the present embodiment will be briefly described by taking the case of setting the field of view of fog as an example.

In order to represent the field of view of the fog, the color data of each polygon should be specified so that the color of all polygons becomes closer to white as the distance increases. That is, the actual color of a polygon is, for example, an RGB color code (17
0, 65, 30). Then, in the field of view of fog, the color of this polygon needs to be closer to white as it gets farther from the player, and at the farthest position, a code in which all RGB are equal, for example, (100, 10).
0, 100) is desirable. Therefore, in this embodiment, the color code changing unit 194 changes the value of the color code in the color palette as shown in FIG. As shown in the figure, it is understood that the value of the color code (170, 65, 30) gradually approaches white (100, 100, 100). Similarly, color codes corresponding to other color numbers are changed in the same manner. Then, these color codes are changed every time the player selects a game surface and changes the setting of the visibility condition at the start of the game.

In FIG. 16, the color palette 0
Is a color palette used for the closest polygon to the player's own machine, and conversely, color palette 7 is a color palette used for the farthest polygon. The color palettes 2 to 6 are color palettes used for polygons located at a distance between them, and are associated with each other in advance according to the distance.

The palette number changing section 192 sets which palette number each polygon uses for the color palette. That is, first, the pallet number changing unit 192 calculates the distance between itself and the polygon. However, the data of this distance is used as the image supply unit 212.
This data is used in the sorting process performed in step 1. This data is used in this embodiment. Next, it is determined which pallet number of the color pallet to use, that is, which color pallet to use in FIG. 16 according to the distance. Once decided, the palette number and the color number given in advance to each polygon specify the color code used for all the dots in the polygon, and the color corresponding to the color code specifies the color code in the polygon. All dots will be filled.

In the visual field setting unit 190, the color code of the color palette unit 196 is changed by the color code changing unit 194 in accordance with the surface selected by the player to set the visual field. As a specific example, if it is fog, the code of the farthest color palette is set to (1
00, 100, 100), and at night, for example, (0, 0, 0). Also, if it is a sunset (2
00, 50, 30) to slightly enhance the red color. Also,
As for the sea, the deep sea makes blue close to black as (0, 0, 50), and the shallow sea makes blue as (50, 50, 200). Also, for example, if the place where the future tank game is played is a green planet, add a little green to the element of fog,
If it is a sandstorm, add a little yellow.

As described above, according to the embodiment shown in FIG. 15, various visual field conditions can be set.

In the embodiment described above, the marker 3
The image display of 0 and the sight 40 is performed by the frame image forming unit 180.
In 2), a two-dimensional frame image is formed, and this is displayed by being superposed on the pseudo three-dimensional image by the image forming unit 240. However, this display can also be performed by the embodiment having the configuration shown in FIG. 17, for example. In the embodiment shown in FIG. 17, the marker setting unit 150 and the aiming setting unit 170 set the marker 3 in the object information storage unit 104.
By generating the object information of the three-dimensional object corresponding to 0 and the sight 40, the marker 30 and the sight 40 are displayed as an image. In this case, the position information of the marker 30 is set to the position on the pseudo three-dimensional image corresponding to the position of the enemy future tank 22 on the pseudo three-dimensional image, that is, the position of point C in FIG. 11A, by the calculation by the marker position setting unit 154. The position information of the sight 40 is set by setting it in the substantially central portion on the screen. By setting in this way, for example, the marker 30 is displayed at the position of the point C in FIG. 11A by the perspective conversion by the perspective conversion unit 220 when the enemy future tank 22 is in the display area 2. Will be. On the contrary, if the enemy future tank 22 is not in the display area 2,
Clipped out by the clipping processing unit 218,
It will not be displayed. (2) Modification of Marker Shape, etc. In FIG. 18, based on the target state information of the target, the marker 3
A block diagram of an embodiment in which the shape or color of 0 or a combination thereof is displayed is shown.

As shown in the figure, this embodiment has a configuration in which a marker changing unit 156 and a target state information calculating unit 112 are newly added to the embodiment shown in FIG.

Here, the target state information calculation unit 112 is built in, for example, the central processing unit 102, calculates the target state information, and outputs it to the marker changing unit 156. Here, the target state information is, for example, the remaining durability against the attack of the target, whether the target is within the tracking range of the missile, the remaining number of missiles owned by the target, the direction in which the target is facing, the target and the target Information such as the distance to the aircraft can be considered.

The marker changing section 156 changes the shape or color of the marker 30 or the combination thereof according to the target state information.

The operation of this embodiment will be briefly described below with reference to FIG.

First, as in the embodiment shown in FIG. 10, the display area determining unit 110 displays the enemy future tank 22 in the display area 2
It is determined whether or not it exists inside, and based on the result,
The marker display determination unit 152 determines whether or not to display the marker 30. Then, the marker position setting unit 154
At, the position where the marker 30 is displayed is calculated.

Next, the target state information calculation unit 112 provided in the central processing unit 102 calculates the target state information of the target, that is, the enemy future tank 22. Then, the marker changing unit 156 changes the shape of the marker or the like based on the target state information. For example, in FIG. 19A, based on the target state information from the target state information calculation unit 112 that the enemy future tank 22 is within the tracking range of the missile,
The marker changing unit 156 changes the shape of the marker 30 from a square to a diamond. Thus, in this embodiment,
The change in the shape of the marker 30 allows the player to be visually informed of the target state information. As a result, the player can immediately grasp the state of the enemy and immediately take the next action, which is an optimum aiming system in the shooting game in which the situation changes drastically. Also,
The marker 30 is always attached to the enemy future tank 22 as described above. Therefore, by expressing the target state information by using the marker 30 attached to the enemy in this way, the player does not need to move the line of sight in another direction to confirm the target state information. As a result, the player is able to concentrate more on aiming at the enemy, which makes the attack much easier and it is understood that this aiming system is a very good aiming system.

FIG. 19B shows a scene in which a missile 98 fired by its own aircraft hits an enemy and a fire pillar 99 is generated. As a result, as shown in the shield display portion 54 of FIG. 19C, the shield amount of the enemy is greatly reduced, and the enemy is destroyed by another missile attack.

At this time, from the target state information calculation unit 112,
The target state information indicating the durability against the attack of the enemy future tank 22 is input to the marker changing unit 156, and the marker changing unit 15
6 causes the marker 30 to blink in red and white as shown in FIGS. 19 (c) and 19 (d). By making the marker 30 blink in red and white in this way,
The player can visually and simply understand that the enemy future tank 22 can be destroyed by another attack.
You will immediately be attacked by the next attack.

In addition to this, for example, the color of the marker 30 may be sequentially changed from blue to red, for example, in accordance with the remaining durability of the enemy. As a result, the player can visually grasp the state of the enemy immediately and can immediately determine whether it is time to attack or defend.

Further, for example, the shape of the marker 30 may be changed in the marker changing section 156 based on the target state information regarding the direction in which the enemy is facing. In this case, the target state information can be visually represented by representing the shape of the marker 30 with, for example, an arrow indicating the direction in which the enemy is facing. As a result, the player can immediately grasp the direction of the enemy, and if the barrel of the enemy is not facing the direction of the player's plane, the player will immediately attack as an opportunity to attack, and conversely, the barrel of the enemy will be facing this direction. When the aircraft has a small amount of shield, it is possible to immediately take action to escape.

Further, the target state information, which is the remaining number of missiles of the enemy future tank 22 for example, can be visually represented by arranging it around the marker 30 in the form of a figure in the shape of a missile, for example. .

20A and 20B, this marker 3
An example in which the shape of 0 and the display position of the marker 30 are changed based on the enemy position information is shown. This example is shown in FIG.
2 (A) and (B). That is, in FIG. 12B, when the enemy future tank 22 goes out of the display area 2, the marker 30 is no longer displayed, and the player cannot detect the enemy position 52. There was no method other than using the position detection radar 50. On the other hand, in FIG. 20 (B), when the enemy future tank 22 goes out of the display area 2, it is located at the position M corresponding to the existing direction of the enemy future tank 22 on the peripheral portion of the screen. The marker 30 is displayed. Further, in this case, by changing the shape of the marker 30 to a shape that indicates the direction of existence of the enemy future tank 22, the player can visually recognize the direction of existence of the enemy. 11A and 11B schematically show the above marker setting method. With this marker setting, the player can easily grasp the enemy's position regardless of whether or not the enemy future tank 22 is present in the display area 2. In particular, as shown in FIGS. 20A and 20B, the marker 30 is displayed at the point M, which is a position where the enemy is out of the visual field. Therefore, the player who is following the movement of the enemy future tank 22 does not need to move the line of sight to, for example, the position of the enemy position detecting radar 50 in order to confirm the position of the enemy again. As a result, it is possible to continuously chase and attack the enemy future tank 22 without changing the direction of the line of sight.

As shown in FIGS. 19A and 19B, in this embodiment, the missile 98 has a tracking function. Below, the tracking function of this missile is shown in FIG.
The example will be briefly described.

In the embodiment shown in FIG. 21, the terrain information stored in the terrain information storage unit 106 can be reflected in the calculation of the moving position of the bullet in the bullet movement calculation unit 122 and the hit determination in the hit determination unit 126. Has become. In the case where the three-dimensional topographical information can be reflected in the movement position and hit determination of the bullet in this way, there is a problem that the aiming work of the bullet becomes more difficult than in the past. In this way, if the game configuration is such that the attacking player's bullets do not hit easily, the game will not progress and it will not be possible to provide a three-dimensional game full of speed. So, in this example,
A new bullet tracking system has been installed to solve this problem.

FIG. 21 shows a block diagram of an embodiment in which the tracking system is provided for the bullet in this way. Figure 21
The embodiment shown in FIG. 18 is different from the embodiment shown in FIG. 18 in that a trigger determination unit 142 and an ammunition processing unit 120 are newly added.

The trigger determination unit 142 determines whether or not the player has triggered the bullet, and thus a firing signal for the bullet is formed. The bullets referred to here are not limited to machine guns, missiles and the like used in this three-dimensional game, but include all kinds of weapons such as light guns such as lasers, axes and arrows.

The bullet processing unit 120 includes a bullet movement calculation unit 122,
The configuration includes a tracking movement calculation unit 124 and a hit determination unit 126. The bullet movement calculation unit 122 calculates the movement position of the bullet from the object information of the moving body changed by the object information changing unit 108 and the firing signal of the bullet from the trigger determination unit 142. In the tracking movement calculation unit 124,
A calculation is performed to change the moving position of this bullet so as to track the target.

In the hit determination unit 126, the object information of the target, for example, the enemy future tank 22 is read from the object information storage unit 104, and from this object information and the movement position of the bullet changed by the tracking movement calculation unit 124. ,
A hit determination is made. When hit, the hit determination information is reflected in the object information of various three-dimensional objects stored in the object information storage unit 104.

Next, the operation of this embodiment will be described.

First, the object information changing unit 108 uses the terrain data stored in the terrain information storage unit 106 to change the object information of the moving body, that is, the future tank 20.

When the player operates the triggers 16 and 18 connected to the operation section 140 in this state, the trigger operation signal is input to the trigger determination section 142 via the operation section 140. Then, the trigger determination unit 142 determines whether or not the trigger of the machine gun or missile has been pulled, and when it is determined that the trigger has been pulled, a firing signal of the machine gun or missile is formed, and this firing signal is the bullet of the bullet processing unit 120. It is output to the movement calculation unit 122.

By the input of the firing signal, the bullet movement calculation unit 122 causes the object information storage unit 104 to change the object information (X0, Y0, Z0, θ0, φ0) of the changed moving object at the moment when the firing signal is input. , Ρ0) to read.

Next, the bullet movement calculation unit 122 determines that the firing position is (X0, Y0, Z0) and the firing direction is (θ0, φ0).
Then, the moving position of the bullet whose firing time is the time when the firing signal is input is calculated. In this case, the movement of the bullet obtained by calculating the movement position of the bullet is a linear movement in the direction, for example, assuming a future tank game in space. On the other hand, in a future tank game on the earth or the like, if gravity is taken into consideration, it becomes a parabolic movement. Then, if the parabolic movement is performed in this way, the future tank 20
It is possible to hit the bullets even if the barrel of the is not perfectly suitable for the enemy future tank 22. That is, as shown in FIG. 3, the first and second plateaus 76 and 78 are interposed between the future tank 20 and the enemy future tank 22, and even if the enemy cannot see the enemy tank from a long distance, for example, a long distance. It is possible to attack the enemy with the gun. As a result, the enemy can be attacked from a blind spot position that cannot be seen by the enemy due to the three-dimensional terrain, and the game can be made even more interesting.

In this future tank game, the axis of attack is set so as to substantially coincide with the front direction of the moving body. Therefore, the object information of the moving body is set to the initial position of the bullet firing position and the firing direction. The value can be used almost as is.
However, depending on the game, it may be set such that the moving body and the attack direction, that is, the direction of the barrel can be operated individually.
Then, in this case, the bullet movement calculation unit 122 determines the initial values of the firing position and the firing direction of the bullet based on the object information of the moving body and the operation signal of the barrel.

Next, the movement position of the bullet, for example, the missile's bullet, is input from the bullet movement calculation unit 122 to the tracking movement calculation unit 124. As described above, the movement position of the missile's bullet reflects the topographical information. It is calculated as the moving position of the shot.

The tracking movement calculation unit 124 performs a calculation for changing the movement position of the missile bullet based on the object information of the enemy future tank 22 stored in the object information storage unit 104. 22 and 23 show examples of the tracking movement position of the missile changed by the tracking movement calculation unit 124. In FIG. 22, when the missile hits by the tracking, FIG. 23 tracks the missile but hits the missile. If not, it is indicated. The calculation of the tracking movement position will be described below with reference to FIGS. It should be noted that although a two-dimensional case will be described here for the sake of simplicity, this calculation is actually performed in three dimensions.

Now, let the initial position of the missile 98 be M0 (X0
, Y0), the position of the enemy future tank 22 is set to En (XE
n, YEn). In addition, the calculation is performed for each frame (1/6
0 seconds) and the time of one frame is T.

First, the missile initial position M0 (X0, Y0) and the missile velocity V (V
X, VY) is input. As a result, if the change calculation is not performed in the tracking movement calculation unit 124, the movement position M1 (X1, X1) of the next missile is M1 (X1, X1) = M0 (X0, Y0) + V (VX ,
VY) × T = (X0 + VX × T, Y0 + VY × T) =
It is calculated as (X0 + VX * T, Y0 + VY * T). Therefore, with such a calculation method,
In both cases of FIG. 22 and FIG. 23, the missile will not hit the enemy future tank 22.

On the other hand, in the tracking movement calculation unit 124,
First, from the object information storage unit 104, the enemy future tank 2
The initial position E0 (XE0, YE0) of No. 2 is read out, whereby the moving position M1 (X1, Y1) of the next missile is: D0 (DX0, DY0) = E0 (XE0, YE0) -M0 (X0
, Y0) M1 (X1, Y1) = M (X0, Y0) + V (VX, VY)
It is calculated as × T + K × D0 (DX0, DY0). Therefore, X1 and Y1 are calculated as follows: X1 = X0 + VX * T + K * (XE0-X0) Y1 = Y0 + VY * T + K * (YE0-Y0). Here, K is a tracking constant, and the larger K is, the higher the tracking power of the missile can be.

Similarly, the next moving position M of the missile
2 (X2, Y2), M3 (X3, Y3), ------, Mn
(Xn, Yn) is calculated as follows.

X2 = X1 + VX * T + K * (XE1-X1) Y2 = Y1 + VY * T + K * (YE1-Y1) X3 = X2 + VX * T + K * (XE2-X2) Y3 = Y2 + VY * T + K * (Y2 + T + K * (E2) ) Xn = Xn-1 + VX * T + K * (XE (n-1) -X (n-1)) Yn = Yn-1 + VY * T + K * (YE (n-1) -Y (n-1)) In this way, the movement position of the bullet is tracked by the movement calculation unit 124.
When the enemy future tank 22 is finally positioned in the traveling direction of the missile 98 as a result of the change calculation by, the missile 98 hits the enemy future tank 22 as shown in FIG. On the contrary, if the enemy future tank 22 is not located in the traveling direction, the missile 9
8 will not hit the enemy future tank 22. Further, as can be seen from the above formula, if the enemy future tank 22 escapes faster than the tracking force of the missile, the enemy future tank 22 can escape from the missile attack. Therefore, by appropriately selecting the value of the tracking constant K in consideration of the speed of the enemy future tank 22 and the like, it is possible to adjust the hit range, thereby adjusting the difficulty level of the game. Becomes

The change calculation of the missile tracking is not limited to the above formula, and various formulas can be used.
For example, by using the angle θ between the advancing direction of the missile and the direction of the enemy future tank 22 shown in FIGS. 22 and 23, Xn = Xn-1 + VX * T + K * [theta] Xn-1 Yn = Yn-1 + VY * It can also be calculated as T + K × θYn−1.

In the hit judging section 126, the bullet movement calculating section 12
2 and the enemy future tank 22 or the obstacle 8 at the movement position of the bullet changed by the tracking movement calculation unit 124.
Whether or not there is no topographical information such as 0 or the second and third plateaus 76 is checked by referring to the respective object information in the object information storage unit 104, and a hit determination signal according to the situation is output.

For example, if the enemy future tank 22 is located at the movement position of the bullet, the enemy future tank 2 is determined by the hit determination signal.
A three-dimensional object that represents hitting position 2
For example, a three-dimensional object of a pillar of fire is formed. Specifically, in the object information storage unit 104, new object information of a pillar of fire whose object information (X, Y, Z) is the same as the position of the enemy future tank 22 is newly formed. Also,
At the same time, the damage given to the enemy future tank 22 by this hit bullet is calculated. When it is determined that the enemy future tank 22 is destroyed by the calculation of this damage,
Processing such as deleting the object information of the enemy future tank 22 stored in the object information storage unit 104 is performed. If it is determined that the enemy future tank 22 has been deformed due to the damage of the bullet, although it was not destroyed, the enemy future tank 22
The index of the object information indicating the is changed to the index of the object information indicating the transformed enemy future tank. As a result, the image combining unit 200 can display the deformed enemy future tank.

If, for example, the obstacle 80 is located at the moving position of the bullet, the object information of the obstacle 80 in the object information storage unit 104 is deleted. This makes it possible to destroy the obstacle 80 with a bullet.

Further, for example, when there is a terrain such as a second plateau at the moving position of the bullet, the bullet becomes invalid and the object information of the bullet in the object information storage unit 104 is erased.

After changing the object information as described above, the image synthesizing section 200 synthesizes a pseudo three-dimensional image according to the changed object information.

The missile 98 is shown in FIGS.
Shows an example of a pseudo three-dimensional image until the player tracks the enemy future tank 22 and hits. The figure (a) is a state when the future tank 20 launches the missile 98. As shown in the figure, the future tank 20 of the player's aircraft is located on the slope 75. Therefore, the barrel of the future tank 20 does not face the enemy future tank 22. For this reason, if the missile 98 does not have a tracking system, the future tank 20 of its own cannot hit the enemy with the missile 98. FIGS. 7B and 7C show how the missile 98 follows the enemy future tank 22 after the launch. At this point, if the enemy future tank 22 escapes and the escape speed is high, the missile 98 cannot be tracked and the missile 98 does not hit. FIG. 3D shows a pseudo three-dimensional image when the missile 98 hits the enemy future tank 22 by tracking. In this case, as shown in FIG.
However, the mark of the hit on the position of the enemy future tank 22, that is, the pillar of fire 9
I'm ordering to give a 9.

As described above, according to the present embodiment, even in the case where the terrain information is reflected in the movement position and the hit judgment of the bullet in the three-dimensional terrain, the tracking system is used to detect the enemy. You can set the game so that you can easily attack. Then, in this case, by appropriately adjusting the tracking constant K according to the speed of the enemy and the like, it is possible to set the game of various difficulty levels, and realize a very flexible three-dimensional game device. You can do it. (3) Setting of Aim Displaying Display of Own Device Status Information FIG. 25 shows a block diagram of an embodiment in which the own device status information indicating the condition of the own device is intensively displayed in the vicinity of the aim 40. .

As shown in the figure, this embodiment is different from the embodiment shown in FIG.
4. It has a configuration including the own device status information display setting unit 172.

The own machine status information calculation unit 114 is built in, for example, the central processing unit 102, calculates own machine status information, and outputs it to the own machine status information display setting unit 172. Here, the own-machine state information means, for example, information such as the number of remaining missiles of the own-machine, the durability against the attack of the own-machine, the direction of the own-machine, the fuel of the own-machine, and the like.

The own-machine status information display setting section 172 is set to display these own-machine status information near the sight 40. Then, the setting information for the display of the own-machine state information is output to the frame image forming unit 180 together with the setting information for the display of the sight 40, and is displayed as a two-dimensional frame image so as to be superimposed on the pseudo three-dimensional image.

For example, in FIGS. 20 (a) and 20 (b), the missile remaining number 43 is displayed just above the aim 40 based on the own state information. In this way, by displaying the missile remaining number display 43 just above the aim 40, the player can know the number of missile remaining of his / her own without moving the line of sight. As a result, for example, it is possible to effectively prevent a situation in which the enemy is approached, but the number of missiles remaining is not enough to cause damage.

FIG. 26 shows another example of the own-machine status information to be displayed.

FIGS. 26A to 26C show the case where the shield amount 44 of the player's aircraft is displayed just above the aim 40 and the shield amount 45 of the enemy is displayed just below the aim 40. In this case, the missile remaining number 43 of the own aircraft is also displayed immediately to the left of the aim 40.

Then, the shield amount 44 of the own machine is shown in FIG.
When the number decreases as shown in (a) to (c) and the state is destroyed by another missile attack, FIG.
The warning 46 blinks as shown in (c). This allows the player to take action to avoid a battle with the enemy in order to obtain an item that restores the shield. In addition, in FIGS. 26A to 26C, since the shield amount 44 of the player's aircraft and the shield amount 45 of the enemy can be seen at the same time, it is possible to immediately judge whether the attack or the defense. Furthermore, since these displays are centrally arranged near the aim, the player can confirm the information without moving the line of sight from the aim so much.
It is understood to be a good aiming system. In this respect,
For example, in the display screen shown in FIG. 20A, the shield display unit 54 is arranged in the left corner of the screen, so that almost no player can see it during the battle, and the display method of the present embodiment is more preferable. It is clear that this is a good display method.

26 (d) and 26 (e), a compass 47 indicating the state of the aircraft in which the aircraft is facing north, south, east, west is displayed near the sight. There is. As a result, the player can immediately check in which direction of north, south, east, and west the player is heading. That is,
With the enemy position detection radar 50 shown in FIG. 20A, only the relative positional relationship between the own aircraft and the enemy could be grasped. On the other hand, by displaying the compass 47, the player can immediately check the absolute direction of the player's own machine without shifting the line of sight.

As described above, according to this embodiment, it is possible to concentrate and display various kinds of own-machine state information in the vicinity of the sight. Then, as described above, the target state information of the enemy can be displayed also on the marker 30 which is always attached to the enemy future tank 22. As a result, with these combinations, the player aims at the enemy future tank 22 while aiming at
It is possible to intensively see all of the self-opportunity state information and the target state information without changing the line of sight. As a result, it is understood that the aiming system based on these combinations is the optimum aiming system in the three-dimensional game device that freely moves around in the virtual three-dimensional space to attack the enemy. (4) Multi-player type game FIG. 27 shows an example of a block diagram in the case where the three-dimensional game device according to the present invention has a person-to-person multi-player type game configuration.

As shown in the figure, in this case, two or more operation units 140, the game space calculation unit 100, the object information storage unit 104, the image composition unit 200, and the CRT having the same configuration are prepared. Then, as shown in the figure, the object information stored in the object information storage unit 104, the machine state information calculated by the machine state information calculation unit 114, and the target state information calculated by the target state information calculation unit 112. The three-dimensional game device can have the multi-player type game configuration shown in FIG. Further, in the case of a game configuration in which a missile, a machine gun or the like is used to attack, the object information regarding this bullet is also made common. The common method may be communication or the like, or the boards on which the object information storage units 104 and 104 are installed may be standardized and connected.

In the case of the multi-player type as described above, it is not necessary to make all the three-dimensional objects forming the virtual three-dimensional common, and for example, the virtual three-dimensional space which the player 302 and the player 303 can see. By making the composition slightly different, it is possible to configure a game space that is rich in variety.

Further, the configuration of the present three-dimensional game device as a multiplayer game is not limited to that shown in FIG. For example, during (1/60) second which is one frame,
It is set so that there can exist a plurality of data groups including frame data shown in FIG. 7A, object data continuous with the frame data, and polygon data. By doing this, each frame data of a plurality of existing data groups
It is possible to set different viewpoint positions and viewpoint directions. By setting in this way, one game space computing unit 10 can be used within the range permitted by the speed of hardware.
0, the image composition unit 200 can form a plurality of pseudo three-dimensional images having different viewpoint positions and viewpoint directions. Then, by displaying the pseudo three-dimensional images viewed from different viewpoint positions and viewpoint directions on the CRT of each player, it is possible to eliminate the need for providing a plurality of image composition units and game space calculation units as shown in FIG. Also, a multi-player type three-dimensional game device can be realized.

The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the gist of the present invention.

For example, the three-dimensional game device according to the present invention can be applied to devices having various hardware configurations. That is, the invention can be applied to, for example, a video game device for business use, a game device for attraction as described above, or a driving simulation for a driving school. Also,
For example, it can be applied to a home video game device having a configuration as shown in FIG.

This household video game device comprises a game cartridge 401 and a game machine main body 400.
Connected by a connector 498. The game cartridge 401 includes an auxiliary calculation processing unit 410 and a first storage unit 48.
0, a second storage unit 490 is included. The first storage unit 480 is formed of, for example, a nonvolatile memory, and has the object information storage unit 104 and the three-dimensional image information storage unit 20.
4 is included. In addition, the auxiliary processing calculation unit 410
Includes an image supply unit 212, an image forming unit 240, a marker setting unit 150, an aiming setting unit 170, and a control unit 214. Further, the second storage unit 490 is composed of a rewritable memory.

This home video game device operates almost in the same manner as the embodiment shown in FIG. That is, the object information stored in the first storage unit 480 and the operation unit 40
Using the operation signal from 8, the central processing unit 102 and the auxiliary arithmetic processing unit 410 set the game space, that is, set the object information. Next, using this object information and the three-dimensional image information stored in the first storage unit 480, the auxiliary processing calculation unit 410 and the central processing unit 1
A pseudo three-dimensional image is calculated by 02, and the result is stored in the second storage unit 490. Thereafter, the stored image information is output as an image via the image processing unit 404 and, if necessary, the video RAM 406.

Further, the marker setting unit 150 and the aiming setting unit 1
70, the marker 30 and the aim 40 on the pseudo three-dimensional image.
Can also be displayed.

According to the home-use video game having this structure,
For example, when changing the image synthesizing method, there is almost no need to change the expensive game machine main body 400, and it suffices to simply change the arithmetic processing of the auxiliary arithmetic processing unit 410 of the game cartridge 401.
