Real-Time Line- and Disk-Light Shading with Linearly Transformed Cosines

Eric Heitz and Stephen Hill

ACM SIGGRAPH Courses 2017

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.
