As for 3D visual clothing simulations, the primary problems are the sense of the reality of fabric and the efficiency for collision operation. For these reasons, we simulate the sense of reality of the fabric using an approximate implicit integration and the texture mapping technique. Besides, we improve the efficiency for collision operation using the vector and voxel model.
