In this paper, a compression method of encoding/decoding 3D mesh based on octree is proposed. Vertices of the 3D mesh are reclassified according to the octree rule. We analyse all the nodes of the octree statistically to identify the type of nodes which accounts for the max proportion and encode them with fewer bits. According to the transmission sequence of geometric information, we rearrange topology and attribute information and encode them. Progressive strategies adopted by the single model and the scene are different in order to maximize the use of network bandwidth and computational performance of local machines. This method has high compression rate, is adapt to network transmission with short response time at the client and can control the level of detail of the model decoding.
