Abstract: The browsing of 3D models can be realized by parsing the 3DS format file based on OpenGL. The significant innovation of this paper is to do the point selection of 3D models through high accuracy interactive operation. On the basis of these, the operation of measure and management can be completed. The expressive ability and applicable value of 3D models are greatly improved by using these techniques.
