Re-usable component design for supporting 3D modeling and simulation

A component level designing method based on object-orientation is presented in this paper, which supports re-usable 3D graphics. The performance, the designing method and primitive growing algorithms are analyzed. A component is realized which supports the 3D virtual scene, modeling, and motion simulation. The athletic hierarchical linkage relation and data structure are described. Under the virtual environment, numerical control milling machine modeling and motion process simulation are applied successfully.
