Overview
This repository contains an (evolving) reference implementation for the following publications: * Real-Time Polygonal-Light Shading with Linearly Transformed Cosines (2016) * Real-Time Area Lighting: a Journey From Research to Production (2016) * Linear-Light Shading with Linearly Transformed Cosines (2017) * Real-Time Line- and Disk-Light Shading (2017)
Notes:
- The Linearly Transformed Cosine (LTC) tables in this implementation differ in their parameterisation and storage compared to the original paper. See fitting code and WebGL demos for details.
