Design and Implementation of Cloth Simulation Using GLSL 4.3

摘要

Physically based simulation with 3D objects should provide a realistic expression of object behaviors under various external environments. However, physically based simulation inherently requires a large amount of computational cost in order to estimate the next states of 3D simulatedobjects. Thus it hinders the real-time dynamic simulation with general CPU based computation. In this paper, we designed and implemented the cloth simulation using GPU based parallel processing with GLSL 4.3. The spring forces between connected nodes are calculated and the next positions ofnodes are estimated with simple Euler integration method. In this paper, we provide the results of performance comparison for cloth simulation based on CPU and GPU. The experimental results show that GPU based parallel cloth simulation is about 292 times faster than CPU based cloth simulation.
