Point cloud compression using non-orthogonal projection

An encoding device for point cloud encoding, the encoding device comprising:

• a processor configured to:
• determine, for points of an object represented by a three dimensional (3-D) point cloud, a point size value and a point shape identifier to indicate adjustment of a size and shape of the points of the object for rendering;
• generate a compressed bitstream including two-dimensional (2-D) frames, that represent the 3-D point cloud, each of the 2-D frames including a set of patches, the set of patches including the points of the object represented by the 3-D point cloud;
• and
• generate information for processing the 3-D point cloud, the information including the determined point size value and point shape identifier;
• and
• a communication interface operably connected to the processor, the communication interface configured to transmit, to a decoding device, the compressed bitstream for the 3-D point cloud and the information for processing the 3-D point cloud.

A method for point cloud decoding, the method comprising:

• receiving a compressed bitstream for a three-dimensional (3-D) point cloud;
• receiving information for processing the 3-D point cloud;
• decoding the compressed bitstream into two-dimensional (2-D) frames, that represent the 3-D point cloud, each of the 2-D frames including a set of patches, the set of patches including points of an object represented by the 3-D point cloud;
• decoding the information for processing the 3-D point cloud to identify a point size value and a point shape identifier for the points of the object represented by the 3-D point cloud;
• determining, based on the identified point size value and point shape identifier, a size and shape of the points of the object for rendering;
• and
• rendering, using the determined size and shape, the 3-D point cloud including the object.
