Abstract
A method for coding three-dimensional (3D) content includes: extracting a video frame from a video, where the video frame includes connectivity information associated with the 3D content; and reconstructing the 3D content based on the connectivity information, where the connectivity information includes: segments representing the 3D content; and sorted faces and vertex indices within each segment.
Claims17
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:
- segmenting a mesh representative of the 3D content into segments;
- processing each segment to sort faces and vertex indices within each segment;
- generating a connectivity information frame for each processed segment;
- and
- encoding the connectivity information frames based on a video codec;
- wherein generating the connectivity information frame comprises:
- transforming one-dimensional (1D) connectivity components associated with each processed segment to two-dimensional (2D) connectivity coding sample arrays.
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 comprises:
- segments representing the 3D content;
- and
- sorted faces and vertex indices within each segment;
- wherein the connectivity information comprises two-dimensional (2D) connectivity coding sample arrays based on one-dimensional (1D) components of mesh frames associated with the 3D content.
