Abstract: Methods, systems, computer-readable media, and apparatuses for radiance transfer sampling for augmented reality are presented. In some embodiments, a method includes receiving at least one video frame of an environment. The method further includes generating a surface reconstruction of the environment. The method additionally includes projecting a plurality of rays within the surface reconstruction of the environment. Upon projecting a plurality of rays within the surface reconstruction of the environment, the method includes generating illumination data of the environment from the at least one video frame. The method also includes determining a subset of rays from the plurality of rays in the environment based on areas within the environment needing refinement. The method further includes rendering the virtual object over the video frames based on the plurality of rays excluding the subset of rays.
