Method and apparatus for receiving a volumetric video stream

A system for receiving and rendering volumetric video, comprising:

• a memory for temporarily storing a plurality of quantized points in 3D space;
• one or more processing units being configured to:
• receive and decode a first video track carrying geometry information;
• receive and decode a second video track carrying occupancy information;
• receive and decode an auxiliary metadata description;
• receive and decode a third video track carrying texture information;
• combine the first video track and the second video track with the auxiliary metadata description to perform three dimensional geometry reconstruction to produce one or more geometry positions;
• combine the fourth video track with at least one or more of the first video track, the second video track, the auxiliary metadata description or the third video track to reconstruct one or more color attributes corresponding to the one or more geometry positions;
• combine the one or more geometry positions and the one or more color attributes into a plurality of colored 3D points;
• and
• render the plurality of colored 3D points as a volumetric video using a presentation or projection device.

A computer program product, comprising:

• a nontransitive storage medium, where the computer program product defines processing instructions for decoding a plurality of points in 3D Space, the computer program product, when executed by processing circuitry of a computer, performs a method, the method comprising:
• receiving and decoding a first video track of a volumetric video carrying geometry information;
• receiving and decoding a second video track carrying occupancy information;
• receiving and decoding an auxiliary metadata description from the volumetric video;
• receiving and decoding a third video track carrying texture information;
• combining the first video track and the second video track with the auxiliary metadata description to perform three dimensional geometry reconstruction to produce one or more geometry positions;
• combining the fourth video track with at least one or more of the first video track, the second video track, the auxiliary metadata description or the third video track to reconstruct one or more color attributes corresponding to the one or more geometry positions;
• combining the one or more geometry positions and the one or more color attributes into a plurality of colored 3D points;
• and
• rendering the plurality of colored 3D points as a volumetric video using a presentation or projection device.
