| Abstract: | The paper presents the simulation technology of cloth modeling based on mass spring model. A new method on deformation constraint to avoid super-elastic effect is proposed. A cloth object is approximated to a deformable surface composed of a network of masses and springs, the movement of which is evaluated using the numerical integration of the fundamental law of dynamics. The equation results are obtained using Runge-Kutta algorithm with strain restriction condition. The paper shows good simulation result with little run-time and the good practicability of mass spring model. |
