| Abstract: | Based on the member function and operating symbol about vector operation that vector class encapsulation,the paper makes an inquiry into the collision detection completely of four kinds of contact styles;namely,vertex and vertex,vertex and edge,vertex and face and edge and edge.It provides the method and program code to calculate the minimum distance between collision objects,collision normal vector,relative normal velocity and to detect the contact style. |

| Keywords: | vector class collision detection contact style collision normal vector |
