DATA STRUCTURE OF TRIANGLE MESH INCLUDING WIRE FRAME, METHOD FOR COMPRESSING AND EXPANDING THE TRIANGLE MESH, PROGRAM, AND SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a data structure wherein processings such as compression, storage, transfer or expansion to a triangle mesh including a wire frame are applied without lowering the space efficiency of a storage device, a display speed, and a transfer speed even when a data size increases. SOLUTION: The data structure 1 of the triangle mesh (including a wire frame) in an n-th dimensional space consists of a coordinates table 10 for indicating vertex coordinates in the n-th dimensional space, a triangle mesh table 20 for indicating a triangle mesh (polygon mesh), and a wire frame table 30 for indicating a wire frame allocated to an area from an independent wire frame by discriminating them from each other.
