Abstract
In one embodiment, a computer system may determine an orientation in a 3D space based on sensor data generated by a virtual reality device. The system may generate ray footprints in the 3D space based on the determined orientation. For at least one of the ray footprints, the system may identify a corresponding number of subsamples to generate for that ray footprint and generate one or more coordinates in the ray footprint based on the corresponding number of subsamples. The system may determine visibility of one or more objects defined within the 3D space by projecting a ray from each of the one or more coordinates to test for intersection with the one or more objects. The system may generate an image of the one or more objected based on the determined visibility of the one or more objects.
