Summary: 
Shadow is an important effect that makes virtual 3D scenes more realistic. In this paper, we propose a fast and correct soft shadow generation method for area lights of various shapes and colors. To conduct efficient as well as accurate visibility tests, we exploit the complexity of shadow and area light color.
