Re: Bidirectional related question

It's a matter of mathematical frameworks and playing with units, really. To me, the cleanest framework of all is Veach's path integral formulation of light transport, which only ever deals with radiance. And for this reason I do not recommend the Advanced Global Illumination book. The concepts ther...
