Abstract
A decoding computing device determines a focus area of a view of volumetric visual content, such as a three-dimensional (3D) object or scene, and indicates the focus area in a request for compressed volumetric visual content. A server provides a depth map and an attribute atlas that includes attribute and/or texture information for the focus area that is signaled at a higher resolution than other portions of the volumetric visual content. The decoding device also applies one or more mesh simplification techniques, wherein a higher resolution mesh is used for the focus area. The textures/attributes are projected onto the mesh representations, wherein the mesh representations and projected textures are used to reconstruct the volumetric visual content. Hole filling techniques are then applied, wherein a more sophisticated hole filling technique is used in the focus area.
