Well, i agree to disagree on one thing, caustics are everywhere, from ocean waves, heat, reflections, water, glass, gold, metals, etc.,etcâŚ
Yes, NOW many dont do caustics, it ist true, but once somebody SEES what a good full caustics render looks like, nobody wants to go back.
Seeing the difference between a LuxMLT/PrmanVCM and pathtracing like Arnold/Cycles, and i have to say that once you get good caustics, its really a feeling of âOMG!â, you see all other images like âdry cat foodâ.
And i am not even talking spectral here (MLT), only good RGB caustics.
So, of course i want caustics, they are THE main part of energy transfer over any energy re/de/flecting/fracting surface, and the results are insanely great.
@lukas
wow, thanks for the overview!
i just read this paper: https://mediatech.aalto.fi/publications/graphics/GPT/kettunen2015siggraph_paper.pdf
the MSE is⌠just WOW
Do you thing GPT would be easy to implement, like, is it a big thing (deep rewrite), or only a render kernel âexpansionâ of the existing cycles ?
