Hi! This is indeed very impressive, XMAMan! Say, have you tried to render the atmosphere/cloud scene with UPBP? I have to wonder though how well the algorithm copes with "nature" scenes. Btw, @ ultimatemau, thanks for the tip regarding "Path Guiding in Production". I found it's really a great overvi...

Nice progress!

Thanks, knightcrawler! :-) Here is a another 24 h rendering. I had this fun idea to make a flat earth version of the globe figure. :lol: glossytransmissiveflatearth.jpg The dome is filled with a thin, scattering medium. This creates the glow effect around the sun. The image has other details which I...

Hi Charles, thank you. The link has a typo, but it's clear which paper you mean: "Microfacet-based Normal Mapping for Robust Monte Carlo Path Tracing". The results look really nice. One thing bugs me though. In Figure 18th's caption, the authors state "Our normal-mapping model ... fails the white fu...

@XMAMan you're welcome. Meanwhile, I rendered variations of the Buddha. This time with the new glossy transmissive material. I also added a switch in the material to force a path tracing step instead of getting Li from photons, essentially treating the BSDF as if it was a delta function. No NEE yet....

We know since VCM that photon mapping can be seen as a path sampling method. Therefore, I want to first refer to Raab et al. (2008) "Unbiased Global Illumination with Participating Media" for the concise path integral formulation of volume rendering. I use the stochastic progressive variant of photo...

Hi. Thank you both. Glad you like it. :) Btw., I forgot to say, I rendered the media with "The Beam Radiance Estimate" by Jarosz (2008). I use Embree to do the beam-point query. This is possible since fairly recent support for ray-aligned-disc intersections! So, if you happen read this, Embree devel...

Oh, forgive me, I missed the motion blur on the fireball even! Now I understand. Nice!

No offense, but how is it different from regular area lights?
Anyway, I really like the renderings in your first post. They look good and they are so clean. Good job. Oh and the scene with the crystal man is very cute

Here are some new results from my renderer. I've been messing with photon mapping ... Check if physics are working as intended. The beam is supposed to be focused like that. I let the construction of the scene be guided by the so called Lensmaker's equation https://en.wikipedia.org/wiki/Lens_(optics...
