Abstract: Methods and systems are provided for using temporal supersampling to increase a displayed resolution associated with peripheral region of a foveated rendering view. A method for enabling reconstitution of higher resolution pixels from a low resolution sampling region for fragment data is provided. The method includes an operation for receiving a fragment from a rasterizer of a GPU and for applying temporal supersampling to the fragment with the low resolution sampling region over a plurality of prior frames to obtain a plurality of color values. The method further includes an operation for reconstituting a plurality of high resolution pixels in a buffer that is based on the plurality of color values obtained via the temporal supersampling. Moreover, the method includes an operation for sending the plurality of high resolution pixels for display.

Abstract: A method for implementing a graphics pipeline. The method includes generating a plurality of bones for an object defining positioning relationships between the bones. The method includes determining a subsystem of bones from the plurality of bones for the object. The method includes determining a foveal region when rendering an image of the virtual scene including the object, wherein the foveal region corresponds to where an attention of a user is directed. The method includes determining that at least one portion of the object is located in a peripheral region for the image. The method includes animating the object by applying a transformation to the subsystem of bones.

Abstract: A method for implementing a graphics pipeline. The method includes building a first shadow map of high resolution, and building a second shadow map based on the first shadow map of lower resolution. The method includes determining a light source affecting a virtual scene, and projecting geometries of objects of an image of the virtual scene onto a plurality of pixels of a display from a first point-of-view. The method includes determining a foveal region when rendering the image, wherein the foveal region corresponds to where an attention of a user is directed. The method includes determining a first set of geometries is drawn to a first pixel, determining the first set of geometries is in shadow based on the light source, and determining the first set of geometries is outside of the foveal region. The method includes rendering the first set of geometries using the second shadow map.

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.
