| Abstract: | The method and step of physical movement simulation of rigid body in real time are stated with geostatics and computer technology.Based on the member function and operating symbol about vector operation that vector class encapsulate,the collision detection of two kinds of contact style named vertex and vertex,vertex and edge are researched.Actual impulse formula of rigid bodies with collision is calculated by momentum and angular momentum theorem, and response model is built.Finally,the collision of 2D rigid bodies is simulated really based on it. |
