摘要

针对骨骼动画中阴影计算耗费时间较大的问题,提出基于CUDA平台的阴影实时仿真方法.利用OPENGL的扩展特性和硬件的图形处理单元GPU的并行计算能力,对大量图形数据进行并行计算,可以加速膏骼动画顶点的矩阵变换以及阴影体的计算.实验结果表明.该方法可以获得很好的加速比,效率提高明显.%There is a real-time shadow simulation method based on CUD A, which is brought up to solve the problem of huge time cost to render the shadow of skeletal animation. It can accelerate the conversion of vertex and the calculation of shadow volume through Data-Parallel processing. The experiment shows, using the powerful GPU capacity of parallel processing and some OPENGL extensions on, that GPU can get much better efficiency, it is obvious that it can speed up the rendering of shadow.
