Abstract:  VRML is the main file format transmitting the 3D model on the Internet,but the complicated scene model contains a large amount of information. Though traditional VRML file has already adopted the compression of a certain form to deal with, the file is still relatively huge. A binary compression algorithm based on VRML file was proposed in this paper. The files were compressed with binary compression, which was suitable for transmitting in the network without causing the congestion of network. At the same time, the data information did not influence visual display quality after compressing.
