Abstract
The connectivity information and mapping information of a mesh surface patch are able to be encoded after projection to 2D. Regarding the connectivity information, the projection operation does not change the connection between vertices, so the same list of connected vertices are able to be carried in the atlas data. Similarly, the mapping information does not change after projection and is able to be carried in the atlas data. Two methods are disclosed for encoding the connectivity and mapping information. For the connectivity information, a video-based method uses neighboring color coding. For mapping coordinates, a method uses the projected vertex position. The connectivity and mapping are also able to be processed by an external mesh encoder. Newly proposed mapping information is able to be taken advantage of to perform temporal compression.
