In this paper, we propose a new generation method of control meshes for subdivision surfaces by using a model simplification. In recent years, opportunity for the use of the three-dimensional model technology called Web3D has increased. However, a refined model representation requires an immense number of polygons, which is inefficient to network transmission. Therefore, much research that aims at efficient network transmission by using model simplification methods and subdivision surface methods is being studied. The previous works are roughly divided into global and local approaches. In some local approaches, although a decompressed object is almost equal to the original object, there is a tendency for the amount of data to increase. We have proposed a new method to convert coarse control meshes for subdivision surfaces from the original object by using a global model simplification scheme. And, we have made sure of the effectiveness of our method through experimentation.
