Abstract: This paper introduces how to simulate the behavior of cloth using a spring-mass system. The method runs efficiently, but has mathematical instability. Combined with shadow volume algorithm, this paper proposes an implicit Euler method, overcomes the problem of real-time shadow for soft object. The method runs very fast, the edge of the generated shadow is very smooth, and visual effect is perfect.

Key words: physical-based simulation, spring-mass system, real-time shadow, shadow volume method
