In this paper, a new method is described for rendering convincing soft shadows from area light source at interactive frame rates. The method is based on the shadow map algorithm and it fully exploits the parallelism of the programmable graphics pipeline. In the method we sample the area light source using parallel linear segments and compute the light contribution of each segment using a completely new method which gives reasonable simulation for soft shadow generated by tiny scene object. We demonstrate that it can generate detailed soft shadow, while achieving the high frame rates. And our approach offers a number of benefits. E.g., it's easy to be adopted by the projects using shadowing map and there is no extra overhead while the c...
