Abstract: A display device, such as a head mounted device (HMD), displays a virtual scene. The display device includes a motion tracker for detecting rotation and/or translation of the display device. The display device also includes a processor that is configured to determine, in response to the detected, an orientation of the display device relative to a plurality of world-aligned viewing frustums that are stationary relative to the virtual scene. The processor is also configured to identify a set of those world-aligned viewing frustums that overlap with an output field of view. The processor is further configured to render pixels of the set of those world-aligned viewing frustums that overlap with an output field of view and upsample the rendered pixels to generate values of display pixels for presentation by the display device.

Abstract: Systems and methods for performing foveated rendering are provided. An example system and method may warp a 3D scene based on a fixation point. The system and method may also render the warped 3D scene to generate a first image. The system and method may also unwarp the first image to generate a second image. For example, the first image may have fewer pixels than the second image.
