Took more than a month of reading and still this video does the better job of explaining GI techniques! Really appreciate all the effort that goes into making these videos.
As someone who recently implemented DDGI, this would have been extremely useful a year ago ahaha Thank you very much for making these freely available, and for your enthusiasm!
I try to implement virtual lights in Touchdesigner, from the screenSpace normal pass. Not sure if is good practice what i am doing… (for loop of 100 positions, dot(pos,normals) and for each iteration random color based on a color analysis of scene and materials, than avereage the result)… but i now have color bleeding and the whole scene looks really less CG!! Thanks for what u teach me. I will share the knowledge amoung my small comunity!! ❤
Thanks for the good explanation. Even if all the occlusion techniques are being considered part of the Global illumination domain they are not, strictly speaking. AO is used for shadowing, to let the shadow casting among the environment/scene objects behave much "smoothly" / to let objects near each other block lightning with a certain amount of accuracy. For Global illumination instead we do refer to low radiance and high radiance techniques which do affect how light bounces among objects and then interacts back.
I really love your videos. If it's not too much work, could you give me a pointer on how light maps would be generated? Would you just raytrace the scene from each texel?
