摘　　要：为提高三维场景实时阴影渲染性能,通过图形硬件编程方法,采用HLSL实现Shadow Map。实验表明,GPU的渲染速度远远大于CPU,在计算负载由传统的CPU转移到GPU处理之后,算法的运行效率得到明显提升。Based on graphics hardware programming method, HLSL is used to realize Shadow Map with a view to improving 3d scene real-time shadow rendering performance.Experiments show that rendering speed of GPU is far higher than that of CPU. The algorithm working efficiency is sharply improved after calculated load transfer from the traditional CPU to the GPU processing.
