Abstract
In one embodiment, a computing system may receive a focal surface map, which may be specified by an application. The system may determine an orientation in a 3D space based on sensor data generated by a virtual reality device. The system may generate first coordinates in the 3D space based on the determined orientation and generate second coordinates using the first coordinates and the focal surface map. Each of the first coordinates is associated with one of the second coordinates. For each of the first coordinates, the system may determine visibility of one or more objects defined within the 3D space by projecting a ray from the first coordinate through the associated second coordinate 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.
