Research on Reverse Engineering System Model Based on Partial Surface Reconstructing

This paper explains general system model of reverse engineering, and a new reverse engineering system model of mechanical product 3D modeling based on partial surface reconstructing is presented.In this system,the 3D model can be reconstructed directly based on volume data.This method makes the realization of reverse engineering more simple and efficient.Moreover, this paper analyses the basic principle and the key technology of the direct volume rendering based on ray tracing method,and also, a new intersecting algorithm in ray tracing method to realize volume rendering is given. The result shows that this algorithm is superior in efficiency and it is import to push ahead with the research on reverse engineering.
