Abstract
Systems and methods of the present disclosure provide solutions that address technological challenges related to 3D content. These solutions include a computer-implemented method for encoding three-dimensional (3D) content comprising: determining connectivity information of a mesh frame; packing the connectivity information of the mesh frame into coding blocks; dividing the coding blocks into connectivity coding units (CCUs) comprising connectivity coding samples; and encoding a video connectivity frame associated with the mesh frame based on the coding blocks and the connectivity coding units.
Claims20
An encoder for encoding three-dimensional (3D) content comprising:
- at least one processor;
- and
- a memory storing instructions that, when executed by the at least one processor, cause the encoder to perform:
- determining connectivity information of a mesh frame;
- packing the connectivity information of the mesh frame into coding blocks;
- dividing the coding blocks into connectivity coding units (CCUs) comprising connectivity coding samples;
- generating a video connectivity frame associated with the mesh frame based on the coding blocks and the connectivity coding units;
- and
- encoding the video connectivity frame based on a video codec.
A decoder for decoding three-dimensional (3D) content comprising:
- at least one processor;
- and
- a memory storing instructions that, when executed by the at least one processor, cause the decoder to perform:
- extracting a video frame from a video, wherein the video frame includes connectivity information associated with the 3D content;
- and
- reconstructing the 3D content based on the connectivity information, wherein the connectivity information is stored in video connectivity frames comprising coding blocks divided into connectivity coding units (CCUs) comprising connectivity coding samples.
