Abstract
Methods and systems for geometry compression. In an embodiment, the present invention compresses three dimensional geometry by (1) extracting at least one primitive from the three dimensional geometry, where each extracted primitive includes vertices and property indices that associate properties with the vertices; (2) quantizing, for each extracted primitive, the properties to a fixed grid; (3) converting, for each extracted primitive, the properties from a first data type to a second data type; and (4) encoding property indices, where the encoded property indices and quantized and converted properties are transmitted via a communication network in order to display the three dimensional geometry.
