COMPARISON OF SEVERAL PARADIGMS FOR ACCELERATING PHYSICAL SIMULATION ON A PC

This paper proposes three paradigms for accelerating physical cloth simulation with cloth-object and cloth-cloth collision detection for dressing virtual bodies. The first one uses parallel threads on the CPU and an image-space based collision detection accelerated on the GPU. In the second the simulation runs entirely on the GPU with compute shaders and the third uses NVidia CUDA for the cloth simulation and NVidia OptiX ray-tracing engine for collision detection. Results of the experiments, comparing the performance and advantages of the three techniques, are presented at the end of the paper.
