Classic triangular mesh subdivision algorithm

This paper makes a concise introduction to seven classic algorithms of triangular mesh subdivision, and makes a classification and comparison between them according to their continuity, own advantage and application status. In order to improve the visualization of triangular mesh subdivision, interactive display control is implemented by using MFC and OpenGL while state machine model based on functional class is used as the software operating pattern. On the basis of this, the prototype implementation of Loop algorithm is performed. The improved method of solving existing problematic issues from prototype implementation is presented.
