Real-Time Line- and Disk-Light Shading with Linearly Transformed Cosines
Eric Heitz (Unity Technologies) and Stephen Hill (Lucasfilm)
ACM SIGGRAPH Courses 2017
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.
- The slides with notes.
- The code of the WebGL demos and the LUT fitting code.
- WebGL demos for quad, line and disk lights.
- The part of the talk dedicated to line lights is available as a free chapter in the GPU Zen book.
