A first portion of the planar representation that is closer than a first portion of a virtual object to a viewpoint and a second portion of the planar representation that is farther than a second portion of the virtual object from the viewpoint is determined based on the height map and the virtual object. A display image is rendered from the viewpoint for display, the display image comprising a first set of pixels corresponding to the first portion of the planar representation and a second set of pixels corresponding to the second portion of the virtual object.

Multi-channel ray casting with distortion meshes to address chromatic aberration

A system for content upsampling comprises a console and a head-mounted display (HMD). The console can select content for presentation and provide the content at a first frame rate. The HMD outputs fast calibration data comprising one or more intermediate estimated positions of a reference point on the HMD. The HMD estimates future positions of the HMD using the fast calibration data, and generates synthetic frames using frames from the content and the future positions of the HMD. The HMD then upsamples the content from the first frame rate to a second frame using the synthetic frames to generate augmented content, wherein the second frame rate is faster than the first frame rate. The HMD presents the augmented content at the second frame rate via an electronic display.

Upsampling content for head-mounted displays

In one embodiment, a computing system may access a first image that is generated at a first frame rate. The system may determine whether a change of a user viewpoint with respect to one or more display contents satisfies a threshold criterion.

The system may generate a number of second images at a second frame rate higher than the first frame rate. When the selected operation mode is the first operation mode, the second images may be generated using a resampling process. When the selected operation mode is the second operation mode, the second images may be generated by transforming one or more previously generated second images that are generated based on the first image.
