Does anybody know what is meant here by Universal Photon-Mapping: http://forums.cgsociety.org/showthread.php?t=1471054
Any known references?

Hm... why to ratrace the PCBs at all? who needs that? Sorry for that kind of question, but that's really exotic application of RT. Just curious.

Hi Josh,
you simply taking wrong integral. Your PDF have to normalize to one over hemisphere.
You are right saying that but the integral you need have to be this one:

For out of core scenes performance improvement can be quite significant. Have a look here https://disney-animation.s3.amazonaws.c ... racing.pdf

Thank's for the link, I plan to implement some microfacet BRDFs as well as a next step. I thought of Phong as about quite simple model to implement for test purposes. But surprisingly it is not so simple. However, I don't understand what you mean by "You don't have to guess/hack about sampling direc...

Hi all! I'm trying to sample modified Phong BRDF with cosine lobe distribution. I have no issues with generation of directions on spherical digon around perfect specular direction, but I have doubts on PDF instead. What I see in the Arvo's thesis in section 4.6.4 tells me I need to use O(n) (where n...

That's a lot of inspiration )) from just a hundred lines of code!
I'v been in Tbilisi in October, it's a pity I didn't know such enthusiasts like you are their )
Keep posting on the progress!

Looks very nice!
And that is just one year of development? Do you write entire renderer from scratch or you base on some other open code?

Hm... looks really nice. Where are you going to use that code, any plans?

Define "hopeless". I've heard that all adaptive MC is biased, but not an actual explanation for the claim. Heck, even non-adaptive MC renderers become biased and inconsistent as soon as tone mapping comes into the picture, especially if there are fireflies. I'm pretty sure adaptive MC is at least c...
