Abstract: A set of planes is determined based on the vertices of a three-dimensional scene. The set of planes is determined independent of any particular orientation with respect to a reference viewpoint of the three-dimensional scene. The vertices are associated with the set of planes and respective textures are associated with the set of planes based on the associated vertices.

Abstract: Aspects of the subject technology provide efficient rendering of three-dimensional scenes, including static or mostly static three-dimensional scenes. The efficient rendering may be achieved by providing a mesh atlas that helps to reduce the number of transparent pixels in a scene that are rendered, facilitate use of GPU depth testing to avoid rendering occluded pixels that are later replaced by opaque foreground pixels, and/or facilitate compact packing of image objects into an atlas. The mesh atlas can be generated in advance, and used at rendering time, for efficient rendering of a three-dimensional scene from a current point of view of a user.
