摘要

Since shadow effects is of importance in 3D Game, this paper mainly works on real-time shadow rendering. Percentage closer filtering is one kind of technique that has proved to be an efficient solution on soft shadow; however, it suffers from aliasing problems. We come up with Gaussian Blur Filtering, which can handle soft shadow edges and solve the problem that Percentage closer filtering makes. Under the satisfaction of visual needs, we use real-time RTT technique to exchange data with GPU. After adding Gaussian Blur Filtering, we can efficiently reduce the computation of CPU and GPU computation; still it produces convincing soft shadow effects.
