I should clarify; the problem isn't energy conservation. It's finding a balance between specular and diffuse reflection. I realize that the Phong model isn't exactly physically based, but what's a good balance between them? Isn't it angle-dependent? Also, I'm trying to premultiply any Fresnel coeff...

Secret sources tell me that the first author is in league with dark forces and that the algorithm might be verbal inspiration by Satan himself :twisted: But that's surely no excuse for a badly written paper. Let's try an exorcism. The idea behind the algorithm is to only create starting points for t...

it's still in the process of being put together, but I would guess you should see things appearing there in the next two weeks

yeah, clouds! this is far more on the physical side than the stuff I do for clouds (I basically only create "artistic" procedural volume data that is evaluated on the fly in my volume path tracer). Thanks for sharing, it gave me a few interesting pointers to more material on the topic!! Clouds are a...

Compare it to other sources. b) In general I recommend "Wyszecki & Stiles - Color science", if you can gain acces to that book. For the ...
