Cloth Simulation Using Hardware Tessellation


Cloth simulation has long been a topic of interest in computer graphics since the early works of Terzopoulos et al.. Over the years many techniques have been developed to simulate cloth, though the general concern has been on the physical accuracy of the simulation. As the simulation gets closer to computational sciences the complexity also increases which at times may come at the cost of real-time performance. With newer and more powerful graphics hardware coming out each year, researchers are starting to shy away from the traditional CPU implementation and turning towards the GPU to offload work. As the parallel nature of the graphics hardware offers much better performance, researcher can process many tasks, originally sequential tasks, simultaneously on the GPU. I propose a solution that will map current industry standard's position-based dynamics on to the new graphics pipeline. The focus is on performance and visual realism rather than physical accuracy. By implementing such solutions on the graphics hardware, more detailed cloth behavior can be simulated with real-time performance. In this paper, the described cloth simulation solution will be done completely on the GPU through the use of hardware tessellation on the new DirectX 11 graphics pipeline. The solution though originally designed specifically for cloth may also be adapted for generic deformable object (soft body dynamics).
