More Information
Summary:A rendering workload for an individual frame can be split between a head-mounted display (HMD) and a host computer that is executing an application. To split a rendering workload for a frame, the HMD may send head tracking data to the host computer, and the head tracking data may be used by the host computer to generate pixel data associated with the frame and extra data in addition to the pixel data. The extra data can include, without limitation, pose data, depth data, motion vector data, and/or extra pixel data. The HMD may receive the pixel data and at least some of the extra data, determine an updated pose for the HMD, and apply re-projection adjustments to the pixel data based on the updated pose and the received extra data to obtain modified pixel data, which is used to present an image on the display panel(s) of the HMD.
