Abstract: In one embodiment, a method includes accessing a surface representing represents one or more virtual objects. The surface is associated with a heightmap and a texture, each of which is generated based on rendered information that was generated at a first frame rate. A set of subframes are then rendered at a second frame rate higher than the first frame rate. Each subframe is generated by determining a current viewpoint of a user, determining visibility information of the surface by casting rays against the heightmap from the current viewpoint, and generating the subframe depicting the surface from the current viewpoint based on the visibility information of the surface and the texture. The set of subframes are then displayed to the user.

Abstract: Multiple data permutation operations in respective different dimensions are used to provide an overall effective data permutation using smaller blocks of data in each permutation than would be used in directly implementing the overall permutation in a single permutation operation. Data that has been permuted in one permutation operation is block interleaved, and the interleaved data is then permuted in a subsequent permutation operation. A matrix transpose is one example of block interleaving that could be applied between permutation operations.

Abstract: 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 select an operation mode from a first operation mode and a second operation mode based on the determination whether the change of the user viewpoint satisfies the 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.

Abstract: 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.
