Abstract:
Methods and systems are provided for enabling foveal adaption of temporal anti-aliasing within a foveated rendering presentation. A method for rendering a multi-resolution scene with anti-aliasing within a head mounted display (HMD) is provided. The method includes an operation for rendering a scene that includes a series of video frames. The method also includes operations for applying anti-aliasing to a first region of the scene using a first jitter offset and applying anti-aliasing to a second region of the scene using a second jitter offset. Further, the method provides for generating a foveated scene that includes the first region and the second region and for sending the foveated scene to be displayed on a display associated with the HMD, wherein the first region is associated with a higher resolution than the second scene and the first jitter offset is smaller than the second jitter offset, according to certain embodiments.
