Funny you should mention this, we have a SIGGRAPH 2017 paper on this topic. =)

We just released it online here: http://drz.disneyresearch.com/~jnovak/p ... index.html

As I understand the way you calculate microfacet pdf stays the same, you just call pdf function for light subpath where wi and wo are swapped. Inverse pdf calculation should be same as you do in bdpt so you can take pbrt as reference. https://github.com/mmp/pbrt-v3/blob/master/src/integrators/bdpt....

Recently I decided to implement a simple dielectric microfacet Bsdf in SmallVCM in order to be able to validate something in my own renderer. The microfacet Bsdf I'm implementing is very simple; just a Phong normal distribution for now to keep things simple and the rest based off of Walter's "Microf...

Toxie posted one like this a while ago, I managed to reproduce the same glitch by accident!

In this case it's the photon tracing part of VCM drawing samples from Sobol in a bad way.

If you look on page 96 of Wenzel Jakob's thesis, he talks about randomly classifying glossy surfaces as either non-specular or specular at each scattering event, probably based on the glossiness level. The particular application in Wenzel's thesis is for Manifold Exploration, but I found that a simi...

Wow, very cool! Would love to see more renderings. More coming soon! I have a couple of cool things in the works. In the meantime, there's a lot more images (and also my writeups and stuff) on my development blog: http://blog.yiningkarlli.com/ How do you handle the lackered material on the chair? M...

Hello all, I've been following the ompf2 (and before that, ompf) boards for some time now, but haven't really posted aside from one or two posts a long time ago. I thought for a first "real" post, I'd share some images from my renderer, called Takua Render. I wrote Takua Render from scratch and have...

Ah, my bad, I didn't notice that post.

What friedlinguini means is the caustics in your newer render are more pronounced/brighter than before, which seems more in line with what one would expect from a complex glass model like your elephant. Is your sphere meant to be a perfect mirror though? If it is, I think you may have some weighting...
