Abstract
There is disclosed a system and method for encoding and decoding a geometry sequence. The method includes performing intraframe and interframe comparisons of geometry within the geometry sequence, selecting one or more faces as index faces and encoding only the index faces, and the differences relative to those index faces as a bit stream for transmission. The method further includes enabling decoding of the faces based upon the prediction type and encoding method selected during the encoding process.
