COMPRESSING THREE-DIMENSIONAL MESH - A simplified explanation of the abstract

This abstract first appeared for US patent application 18417962 titled 'COMPRESSING THREE-DIMENSIONAL MESH

The technique described in this patent application involves compressing a 3D mesh using a computing system.

  • The computing system accesses a topology-coding list and a vertex list representing the 3D mesh.
  • The vertex list contains X, Y, and Z coordinates for ordered vertices in the mesh.
  • A predicted vertex list is constructed based on the vertex list.
  • X, Y, and Z coordinate bit streams are generated, each containing ordered coordinate values.
  • Each coordinate value is represented in a corresponding number of bits.
  • The number of bits for each coordinate value is stored in a memory-size list.
  • The computing system encodes the topology-coding list and memory-size lists using Zstandard coder.

Original Abstract Submitted

Particular embodiments described herein present a technique for compressing a 3D mesh. A computing system may access a topology-coding list and a vertex list representing a 3D mesh. The vertex list may comprise X, Y, and Z coordinates for ordered vertices in the 3D mesh. The computing system may construct a predicted vertex list based on the vertex list. The computing system may generate X, Y, and Z coordinate bit streams. Each coordinate bit stream may comprise ordered coordinate values for a corresponding coordinate in the predicted vertex list. Each coordinate value in a coordinate bit stream may be represented in a corresponding number of bits. The corresponding number of bits may be stored in a memory-size list corresponding to the coordinate bit stream. The computing system may encode the topology-coding list and memory-size lists corresponding to the X, Y, and Z coordinate bit streams using Zstandard coder.
