%X As hard shadows grow unsuitable for reality shading, soft shadows have become popular. But soft shadows need more time to sample the density of the area light source. To save the cost and not influence the sense of reality, this article introduced a method to render fake soft shadow. First, it gave a new method to construct the smooth edges for the penumbra texture, and talked about how to create soft shadows with these smooth edges. The results prove the correctness and real-time of soft shadow.
