一种基于GPU的柔和阴影实现方法研究
Research on Realizing Method of Soft Shadow Based on GPU
摘要
Abstract
The shadow is the important characteristics of reality in the virtual environment. Because of the universal and efficiency,parallel split shadow maps algorithm plays an important role to the real-time shadow rendering in the large scale and complicated virtual environ-ment. But to tower simulation system which is large-scale dynamic scene,alias is still happened,using such as variance shadow maps to improve its effect,and using the powerful floating-point operation ability and parallel processing ability of GPU to accelerate the realiza-tion of shadow,so it can effectively guarantee the authenticity and real-time of the shadow. The experimental results show that the shad-ow generated has soft edge,well anti-aliasing effect,and solving the problem of shadow biasing and light bleeding,achieving the require-ments of real-time simulation.关键词
