Re: Importance Sampling of Many Lights with Adaptive Tree Splitting

We certainly saw your post before getting into this topic (hence the citation :)). I have to admit we didn't look at your code in detail though (or the appleseed gsoc project, which was started after we had been using ours in production for a while).
