Example image reprojection methods are disclosed. In one example, a depth buffer of depth values corresponding to an image produced based on a predicted pose is divided into a plurality of tiles. For each tile of the plurality of tiles, a planar deviation error value that estimates a geometric complexity of the tile and penalizes the tile in proportion to an extent to which a geometry of the tile deviates from a plane is calculated. A tessellated mesh of the plurality of tiles is produced based on the planar deviation error values calculated for the plurality of tiles. An updated pose is received. The tessellated mesh is rendered based on the updated pose to output a reprojected image.

Planar deviation based image reprojection

Examples are disclosed that relate to culling of polygons for efficient rendering of a high-density polygon mesh using one or more compute shaders. Examples include monoscopic and stereoscopic rendering, foveated and non-foveated rendering, and selectively utilizing one or more computer shaders to rasterize very small triangles instead of using a regular rendering pipeline for increased performance.
