Abstract: A method for implementing a graphics pipeline. The method includes determining a plurality of light sources affecting a virtual scene. Geometries of objects of an image of the scene is projected onto a plurality of pixels of a display from a first point-of-view. The pixels are partitioned into a plurality of tiles. A foveal region of highest resolution is defined for the image as displayed, wherein a first subset of pixels is assigned to the foveal region, and wherein a second subset of pixels is assigned to a peripheral region that is outside of the foveal region. A first set of light sources is determined from the plurality of light sources that affect one or more objects displayed in a first tile that is in the peripheral region. At least two light sources from the first set is clustered into a first aggregated light source affecting the first tile when rendering the image in pixels of the first tile.

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 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: 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 generating a system of particles creating an effect in a virtual scene, the system of particles comprising a plurality of particle geometries. The method includes determining a subsystem of particles from the system of particles, the subsystem of particles comprising a subset of particle geometries taken from the plurality of particle geometries. The method includes determining a foveal region when rendering an image of the virtual scene, 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 effect is located in the peripheral region for the image. The method includes rendering the subsystem of particles to generate the effect.
