Multiplying microfacets/GGX
Does anyone know if the product of two microfacet distributions (specifically GGX) is also a microfacet distribution and how to compute the alpha of the new distribution? I found some conversion from alpha to standard deviation and used that along with the product of two gaussian distributions to de...

Re: Insights into random number generator
Fantastic, then I have an idea about what to expect from it.
And thanks for opening up your renderer.

Insights into random number generator
Could you elaborate a bit on the RNG used? In preperation for denoising in my own renderer I'm looking into different random number generators to get a decent set of samples pr pixel and ideally different samples for neighbouring pixels. I see that yours uses what looks like several sets of blue noi...

Re: My little path tracer
If you already have the VNDF sampling from the 2014 paper then implementing the new is trivial. It's the same set of samples with the same PDF, so you just have to copy paste the reference sample method and then you'll have faster GGX sampling

Looks like a made up term that he doesn't bother to define.

Re: Quick Question
Alright. That's basically what I want to do at some point for my own path tracer as well in interactive scenarios. I don't think I've ever read anything about it, since it should be fairly trivial, but http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.155.326&rep=rep1&type=pdf and https://gra...

Re: Quick Question
Yea, that really doesn't explain it. Now it sounds a bit more like (path) filtering, but a bounce count in the range of thousands (at least per individual path) is generally a bit silly.
If it's filtering, then there' been a ton of work done in that field.

Re: Quick Question
What exactly do you mean by progressive depth? Render one bounce at a time and defer the next bounces (if any) to the next render call / frame? If so then I haven't seen anything directly related to that, but there are papers that sort the rays pr bounce, so visualizing them as well is fairly trivia...
