Deformation constraints in the draping of cloth-like objects

摘要

Techniques animating a kind of cloth-like objects based on mass-spring (MS) model are widely used in the real-time simulation systems. A velocity modification algorithm based on the explicit Euler integration method is firstly proposed to overcome the super-elasticity of the MS model, which effectively improves the accuracy and reality without adding extra computational complexity. Both theoretical and experimental analyses prove that the modification algorithm effectively recuperate the stability of the simple Euler method. The new technique, which blends the integration method and modification algorithm for simulating the draping behavior of a kind of flexible objects, is fast, stable accurate, and suitable for the development of 3D garment CAD system.
