Abstract
A decoding computing device receives a bit stream for compressed 3D volumetric content. The bit stream includes video encoded image frames comprising packed attribute patch images and depth maps for the 3D volumetric content. Instead of generating a mesh having a vertex for each depth value signaled in the depth map, the decoder performs a real-time mesh simplification process to reduce a resolution of the mesh, such that the mesh resolution is reduced without exceeding an error threshold, which may be dynamically determined. Additionally, the decoder may perform a re-meshing of particular regions of the mesh for the 3D volumetric content to avoid cracks or gaps.
