US 2025/0157147 A1 · ATLASED COVERAGE MESH FOR THREE-DIMENSIONAL RENDERING

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.

Dependent claims

A method, comprising:

obtaining a representation of a three-dimensional scene, the representation comprising a plurality of discrete layers of scene content that are spatially distributed across the three-dimensional scene;
generating, from the representation comprising the plurality of discrete layers and for a plurality of objects represented in the three-dimensional scene, one or more coverage meshes corresponding to the plurality of objects;
storing a mesh atlas, the mesh atlas comprising the one or more coverage meshes corresponding to the plurality of objects, in association with a two-dimensional image containing representations of the plurality of objects;
and
providing the two-dimensional image and the mesh atlas for rendering of the three-dimensional scene.
