Abstract(ENG)

The Bezier surface are the one of primitives of the real-time rendering library like OpenGL. But subdivision surfaces are not supported in these libraries so efficient replacement is needed. In this paper we have introduced a new approximation scheme converting from Catmull-Clark surfaces to bi-cubic Bezier surfaces. This method can be utilized in the area of games and graphics simulations. While minimum error in approximation, smaller data is produced comparing to the old schemes
