Abstract:
    This invention relates to a compression code/decode method for three-dimension models based on Octree, which redivides the Octree space of the peak information of a three-dimension lattice model to calculate and analyze different kinds of nodes in them to find out one or several with the maximum number of total nodes and carries out less bit coding, re-arranging the topological information and attribute information and code based on the transmission sequence of geometrical information separately and sets separate ascending files to control transmission and display of geometrical information and the synchronous mapping of the topological and attribute information.
