Motion Simulation Of Knitted Cloth Based On CUDA

In recent years, because cloth motion simulation is very useful of games, movies and design of costume design, so it is a hot topic of virtual reality and computer graphics. Although the motion simulation of woven cloth is studied for years, but, because knitted cloth has complex structure, so few people research on it.Computer hardware technology get rapid development , and the graphics programming has become one important part of the computer sciences , with the releasing of CUDA(Compute Unified Device Architecture),which is a common architecture of parallel compute introduced by NVIDA. In this article, we use CUDA to simulate the motion of knitted cloth.At first, I use knit model to simulate the knitted cloth, and I present how to construct the knit model by the NURBS curves. Second, I analyze the force which is on the knit model, optimize that model, and compute the result of position and the velocity of the knit. Finally, I introduce the parallel computing base on CUDA, and compute the result by CUDA. We can see the advantage of CUDA through the experiment result.So far, I optimized the knit model, I get the acceptable results by using the newly developed CUDA programming language to perform high immensity computation tasks such as integration and force analysis ,and using c++ to perform the cloth configuration.
