Fast 3D Mesh Compression Using Shared Vertex Analysis

A trend in 3D mesh compression is codec design with low computational complexity which preserves the input vertex and face order. However, this added information increases the complexity.

Zusammenfassung:A trend in 3D mesh compression is codec design with low computational complexity which preserves the input vertex and face order. However, this added information increases the complexity. We present a fast 3D mesh compression method that compresses the redundant shared vertex information between neighboring faces using simple first‐order differential coding followed by fast entropy coding with a fixed length prefix. Our algorithm is feasible for low complexity designs and maintains the order, which is now part of the MPEG‐4 scalable complexity 3D mesh compression standard. The proposed algorithm is 30 times faster than MPEG‐4 3D mesh coding extension.
