Physical model and numerical solver are the basis of current cloth simulation engines. Currently, research in cloth animation has focused on improving realism as well as computation speed. In this paper we present an improved Verlet algorithm which enhances the capabilities of initial one in three aspects. The first one is using 2-level Taylor series as the startup method. The second one is using a more simplified way to obtain the velocity of the particle through approximate substitution. The third one is using Beeman algorithm when the change of force is greater than the threshold value. The experiment results indicate that this approach is efficient and accurate, and can be used in real-time cloth simulation system.
