Research of non-linear subdivision of triangular mesh model based on VRML

In order to solve the problem of real-time collaborative mutual, a method which utilizing CAD software's interface to realize product model visualization is proposed in paper. The problem of triangular surface with G1 continuous construction, non-linear interpolation and subdivision of triangular mesh, data structure which the algorithm needed and data access method are mainly researched in paper. According to research motioned above, triangular mesh model visualization software based on VRML is developed.
