I appreciate your courses so much, I've been bingeing them like a TV show. Thank you so much for publishing them, you're a true lifesaver and your lectures are by far the best resource for rendering fundamentals I've ever come across!

[@irtberry]

Exactly, I keep watching them as TV show.

I’m a graphic programmer and I’m impress by the quality and the simplicity to explain this equation that is be difficult to understand. I have found many ways to explain it to technical artists but never in a such good and easy way. It is really a great work, thanks for sharing. This lesson is awesome!

I am 18 years old and very interested in Computer Graphics, I just discovered you and those incredible series thanks to Jendrik Illner. I was trying to understand SebH - Atmospheric scattering paper, and this video gave me more information about those complicated equations. You are a legend and just got a new subscriber, teşekkürler :)

[@jonisilva123]

This is such a complex concept and yet you are able to explain it in such a clear way! What a great video, wonderful job, I wish I was one of your students!

[@mohamedmoudene-n5i]

perfect explanation, thank you so much!

If all 3d models of people had Cem's haircut, we'd need no subsurface scattering for the ears!

[@michelangelowebb4362]

Thank you ! I really appreciate your work. It helps me a lot.

[@domdom_hello]

it's perfectly explained.. Thank you sir

What a beautiful lecture, I really enjoyed it. I kind of want to do a graduate in Computer Graphics, should I go to Utah, I wanted to appy to Stanford or Berkley and maybe even CMU.

38:11 I don't think this is necessarily true. Imagine a point light source placed between the teapot and another object. You would get both direct and indirect light from the same direction. The presented assumption breaks down with "non-physical" lights, like they are used in CGI.

[@vishaltewari4357]

For Direct light say, the value of brdf is > 1 for some Wo and Wi, then the outgoing light becomes > incoming light?

[@peterSobieraj]

Mathematically if function is 1 for single point, and 0 everywhere else, then integral is 0.

[@elronnd_9515]

hmmmm ... so, since the rendering equation does not account for the speed of light, that means that it's defined recursively? Does that restrict the range of potential definitions of f_r, then--you have to pick an f_r that makes the whole thing have a stable value? (I guess any f_r that accounts for materials absorbing at least some light will probably satisfy this?)
