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.
