That looks gorgeous. I'm wondering what would be a memory requirements of those additional data for more or less realistic production scene.
Did you also implemented sample weighting described in that paper?

https://www.youtube.com/watch?v=oktNku6gFkM Here is my path traced table pool game: https://www.shadertoy.com/view/MttfW It's pure path tracing with NEE and MIS. Uses simple material(lambert+microfacet with fresnel), simple shapes(spheres, cone, rectangle), single rectangular light and thin lens ca...

Hello world!! It is really interesting Demo. I liked that a lot! I know that it's running on super expensive hardware, not suited for average gamer but still very interesting. As I guess main reason why it uses Volta GPUs is denoising. also seams like it has separate networks for shadow/glossy refle...

Really good results

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.c...

Thanks

ah, Thanks

Great results as always :) Thing which is strange for me in "vcm gpu" video is that photons are very noticeable. Directly visible photons correspond to CD.*L path which should have much lower MIS weight then BPT paths. Am I right? Also in last two videos "BDPT with directional regularization" and "d...

You can directly calculate solid angle of spherical rectangle without triangulation.
