Simulating Inextensible Cloth Using Impulses

Computer simulation of cloth is often plagued by springs being over-stretched. The evaluation of impulses to prevent over-stretching is explained step-by-step. Our impulse approach controls the length of springs by a nonlinear system and then a novel linearization of it into a symmetric positive definite system. The cloth/solid collision handling is integrated into the linearized system seamlessly. Some results based on this method are also presented.
