抽象 (Abstract)
We recently introduced a new real-time area-light shading technique dedicated to lights with polygonal shapes. In this talk, we extend this area-lighting framework to support lights shaped as lines, spheres and disks in addition to polygons.
最近,我们推出了一种新的实时区域灯光着色技术,该技术专门用于具有多边形形状的灯光 。 在本次演讲中,我们扩展了该区域照明框架,以支持除多边形外还形状为线,球和圆盘的光源。
