Abstract
(EN)
Techniques for distributed foveated rendering based on user gaze are described. In an example, an end user device is communicatively coupled with a remote computer and presents images on a display based on gaze data. The user device receives a low resolution background image and high resolution foreground image from the remote computer based on the gaze data. The foreground image is constrained to a foveated region according to the gaze data. The end user device generates a composite image by scaling up the background image and overlaying the foreground image. The composite image is then presented on the display.

L'invention concerne des techniques de rendu fovéal distribué basées sur le regard de l'utilisateur. Dans un exemple, un dispositif d'utilisateur final est couplé en communication à un ordinateur distant et présente des images sur un dispositif d'affichage sur la base de données de regard. Le dispositif d'utilisateur reçoit une image d'arrière-plan à basse résolution et une image d'avant-plan à haute résolution à partir de l'ordinateur situé à distance sur la base des données de regard. L'image d'avant-plan est contrainte vers une région fovéale selon les données de regard. Le dispositif d'utilisateur final génère une image composite par mise à l'échelle de l'image d'arrière-plan et superposition de l'image d'avant-plan. L'image composite est ensuite présentée sur le dispositif d'affichage.
