Fast Polygon Lights (would include Area)

Description of the problem

Some new SIGGRAPH research results. A fast way to do polygonal lights, which would be a generalization of area lights. I find the results compelling. We should have area light support in ThreeJS and this would be an effective way of doing it:

  1. Hey @bhouston, fyi, I’m back from some traveling and jumping into this full-tilt. I have a pretty good sense for the steps to get this implemented.

    Sometime in between now and my last comment, it seems the authors of the paper did a significant, and much needed cleanup pass on their sample code, removing a number of confusing and unused methods and structs.

    Let me know if you’d like to sync up on this, but I’ll be cranking on getting an example page for AreaLights setup. Will try to get my repo deployed to the web so I can post links for work in progress.
