Abstract
(EN)
A first computing device determines a scene graph that is representative of a three-dimensional scene that includes objects to be viewed from a specified virtual camera location. The scene graph is processed locally by the first computing device to generate a raster image. The scene graph is sent to a second computing device, such as a server, that processes the scene graph and generates illumination data. The illumination data may be indicative of a brightness value for a given pixel that is representative of optical effects such as reflection, refraction, and so forth. The illumination data is received by the first computing device. The first computing device combines the raster image and the illumination data to produce an output image. The output image may then be presented using a display device.

Un premier dispositif informatique détermine un graphe de scène qui est représentatif d'une scène tridimensionnelle qui comprend des objets à visualiser à partir d'un emplacement de caméra virtuelle spécifié. Le graphe de scène est traité localement par le premier dispositif informatique pour générer une image matricielle. Le graphe de scène est envoyé à un second dispositif informatique, tel qu'un serveur, qui traite le graphe de scène et génère des données d'éclairage. Les données d'éclairage peuvent être indicatives d'une valeur de luminosité pour un pixel donné qui est représentatif d'effets optiques tels que la réflexion, la réfraction, etc. Les données d'éclairage sont reçues par le premier dispositif informatique. Le premier dispositif informatique combine l'image matricielle et les données d'éclairage pour produire une image de sortie. L'image de sortie peut alors être présentée à l'aide d'un dispositif d'affichage.
