| 摘 要： | 通过几何着色器生成Shadow Volume实时阴影。利用几何着色器能生成新顶点与输出流的特性,将以往由CPU完成的产生封闭阴影体的计算转移到图形处理器中实现。该实现能提高算法渲染效率,可以进一步解放CPU的处理时间。比传统先由CPU生成阴影体雏形的方法更简单,性能更优秀。

| Abstract: | Uses geometry shader to generate shadow volume real-time shadows.The shadow volume is implemented in the CPU in the past,according to generate new vertex and output stream of geometry shader,it is completely transferred to the GPU.The implementation method can improve rendering performance of the algorithm,liberate CPU processing time.It is easier and performance better than traditional methods of CPU first generated shadow volume prototype. |
