Abstract
In one embodiment, a computing system may access surfaces and texel data of an artificial reality scene. The surfaces may be generated based on a first viewing position of a viewer. The system may determine tiles on a display to test for a visibility of the surfaces from a second viewing position. The tiles may include first tiles that need more computational resources and second tiles that need less computational resources. The system may determine a tile order which interleaves the first and second tiles. The system may generate rays based on the tile order. The system may determine the visibility of the surfaces from the second viewing position based on the ray-surface intersections. The system may generate color values of a subframe based on the surface visibility and the texel data. The system may provide the color values to the display.
