xx-area-lights - Real-Time Polygonal-Light Shading with Linearly Transformed Cosines #1609

Open bkaradzic opened 5 years ago

bkaradzic commented 5 years ago

Simplify and move area lights example (no Sponza) from SIGGRAPH 2016 talk into bgfx example:

https://github.com/bkaradzic/bgfx#real-time-polygonal-light-shading-with-linearly-transformed-cosines

This code is already compatible with older version of bgfx, it just need updating in case of API changes, and scene simplification so it doesn't require Sponza.
