I felt bad for myself for not being able to find this channel in the first place

[@mohitsethi99]

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.

[@chadyonfire7878]

whoah this is the best overview of the subject, i had a headache exploring all these methods without getting a good overview

[@ruslankudriachenko5673]

Love your lectures. You are doing a great job.

[@MaximoComperatore]

this is a treasure trove, thanks cem

[@Pepe-yn9pf]

Really good lecture, keep it up!

[@Deescacha]

Love your videos! Thank you so much, Cem!

[@mohitsethi99]

Also check out Surfels based GI computation and STBN. The later is denoising technique, it's pretty new and seems to work really well.

[@ExplorerSpace]

i found all your videos are very helpful. thanks a lot

[@michalturlik7309]

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.

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!

[@TheRealJerseyJoe]

Really enjoyed this lecture.... Thanks Cem !!! (BTW - hope you will continue to make more in future). Thumbs-up and sub'd.

[@konstantinbondarenko5235]

Thank you very much

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!! ❤

[@choi9973]

This is totally better than reading about GI, very useful, well explained. Thank you for creating this contents.

[@theburnner1187]

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?

[@paulomarangoni5566]

amazing, well explained!, is there any possibility of the raytrace course you mentioned going to KZbin in the future?

[@chucktrier]

Wow you are awesome !! Had a blast watching this.

[@Mr4NiceOne]

Oh woow, I started learning about GI like two days ago... what a timing, thanks!

[@LUN-bo2fb]

at 11:59. should direct illumination include reflection and refraction?

[@wmka]

I'm currently doing lightmap in unity right now and found this. thank you and have a good one

[@gokalpates1567]

Dersler için çok teşekkürler.

[@MrMariozzz78]

4x 4090 nvidia is enough for REAL global illunimation or i need a render-farm of pixal o walt disney studio? :=)

[@HylianEvil]

Yess!!

[@acho8387]

at 200 spp (35:00) looks like film grain effect
