GPU-accelerated method for real-time shadow generation (IEEE)
A shadow generation method using GPU features is presented. It is based on shadow volumes and it use z-fail to get the real-time shadow. It can ease the contradiction between improving the accuracy of image and limited memory space. It use OpenGL to program for verification. The result is that it use less time and less cost, but get a more accurate and better real-time map of the shadow.
