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.

在3D虚拟服装的模拟过程中,主要的问题为服装布料的真实性与碰撞运算的效率,透过利用近似隐含法、材质贴图与光学法则达到布料模拟的真实性,并利用向量运算与体素法增加模拟过程中碰撞运算的效率。
