High Performance Virtual Clothing Dynamics: High Performance Collision Detection, Response and Dynamics for Virtual Clothing Simulation Sai Keung Wong

There are three major problems in modeling the natural motion of virtual clothing in a 3D environment: (1) a large number of contact points, (2) the computations of collision information in the presence of numerical errors, and (3) interactions with objects having sharp features. We proposes new techniques that successfully address the three problems. The experimental results show that the proposed techniques can be applied on virtual garments with complex geometry and on unique interactions between continuous and non-smooth surfaces. Our techniques are classified into four categories: (1) culling non-colliding subsurfaces in collision detection, (2) intrinsic collision detection, (3) collision response, and (4) the editing and simulation of special virtual garments. The techniques have been integrated into a high performance system for virtual clothing dynamics.
