Abstract
(EN)
The present disclosure relates to methods and apparatus for graphics processing. In some aspects, the apparatus may receive, by a first device from a second device, first position information corresponding to a first orientation of the second device. The apparatus can also generate, by the first device, first graphical content based on the first position information. Further, the apparatus can also generate, by the first device, motion information for warping the first graphical content. The apparatus can also encode, by the first device, the first graphical content. Additionally, the apparatus can provide, by the first device to the second device, the motion information and the encoded first graphical content.

La présente invention concerne des procédés et un appareil de traitement graphique. Selon certains aspects, au moyen d'un premier dispositif, l'appareil peut : recevoir d'un second dispositif des premières informations de position correspondant à une première orientation du second dispositif ; générer un premier contenu graphique sur la base des premières informations de position ; générer des informations de mouvement permettant de déformer le premier contenu graphique ; coder le premier contenu graphique ; et communiquer au second dispositif les informations de mouvement et le premier contenu graphique codé.
