Abstract

Des procédés de détermination de paramètres d'éclairage pour des environnements virtuels et des environnements physiques sont divulgués. Un premier procédé consiste à obtenir une première caractéristique contextuelle d'un environnement virtuel, à accéder à une mémoire d'un système d'éclairage, le système d'éclairage comprenant un ou plusieurs dispositifs d'éclairage installés dans un environnement physique, la mémoire stockant un ou plusieurs paramètres d'éclairage associés à des secondes caractéristiques contextuelles de l'environnement physique, à obtenir, à partir du ou des paramètres d'éclairage, un paramètre d'éclairage associé à une seconde caractéristique contextuelle de l'environnement physique qui correspond à la première caractéristique contextuelle de l'environnement virtuel, et à rendre l'environnement virtuel sur l'écran et à appliquer le paramètre d'éclairage sélectionné à l'environnement virtuel. Un second procédé comprend : à obtenir une première caractéristique contextuelle d'un environnement physique, à accéder à une mémoire d'un système de réalité virtuelle ou d'un système de réalité augmentée, la mémoire stockant un ou plusieurs paramètres d'éclairage associés à des secondes caractéristiques contextuelles d'un environnement virtuel à rendre sur un écran d'un dispositif de réalité virtuelle ou d'un dispositif de réalité augmentée, à obtenir, à partir du ou des paramètres d'éclairage, un paramètre d'éclairage associé à une seconde caractéristique contextuelle de l'environnement virtuel qui correspond à la première caractéristique contextuelle de l'environnement physique, et à commander un ou plusieurs dispositifs d'éclairage pour appliquer le paramètre d'éclairage sélectionné dans l'environnement physique.
