Original Abstract Submitted
An apparatus includes at least one processor; and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to: receive mesh data; determine a number of subdivisions for the mesh data, wherein a subdivision of the subdivisions comprises a level of detail level, wherein the number of subdivisions comprises a subdivision count; calculate displacement values for the subdivisions; pack the displacement values for the subdivisions in a rectangular region of a video frame; encode the video frame; and signal in or along a video-based dynamic mesh coding bitstream mapping information indicating a relation between displacement values for level of detail levels and regions of the video frame.
