Abstract
In this article the different connectivity and geometry compression algorithms of 3D objects were analyzed and compared. Mesh connectivity is completely unknown to the encoder before the compression. Face Fixer, Edgebreaker and Valence-based approach as well as a Huffman code and an arithmetic code was applied to encode connectivity information and compare experimental results. In geometry, compression typical and non-typical methods of encoding meshes, images, and video were applied. Elias gamma code, Even-Rodeh code, Rice code, Gray code (or RBC), and Fibonacci sequence were among them. Furthermore, the stage of pre-processing coding geometry of mesh models was suggested. Additionally, the use of a Residue numeral system in pre-processing stage was offered.
