| Abstract: | 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. |
