Implemented a proper brdf (Cook-Torrance + GGX) and vndf sampling, now I can do some nicer materials! Here's a shiny ball and a golden dragon:

@lisyarus nice! Is there something like a standard set of validation images? I’ve heard of people going years not realizing they’ve violated energy conservation or something.

@rreusser Hmm, I don't know of any!

@lisyarus Very nice!
Do you have plans for loading significantly larger scenes? Are you anticipating issues there?

@llemarie Thanks! Well it's already using a BVH and it's capable of fairly large scenes, but it will be a bit slow on very large ones. I don't think I'm gonna do anything about it, though. Do you have some particular optimization in mind?

@lisyarus one significant concern is memory. Will you manage to load the new Sponza scene?
I’ve played with the Moana Island scene, that’s a challenge I’ve not conquered yet (: The best I’ve done so far is untextured with missing instances, and that was still 100GB of memory. Lots of optimizations required.

@llemarie Oh, my raytracer runs on GPU so I'll definitely not be able to load 100Gb scenes, haha
