I'm a huge fan of caustics and weird light setups. I'm loving that slab that polarizes out a painting, that's incredible.
My tool of choice is luxrender. ( https://luxcorerender.org/ https://luxcorerender.org/ ) can anyone explain how this is different?
I used it recently to make a chandalier's caustics for a realtime game. https://twitter.com/LeapJosh/status/1328520959968632833 https://twitter.com/LeapJosh/status/1328520959968632833
- magicalhippo 6y agoSo the biggest difference by far is the "inverse" bit. Instead of taking a set of parameters, reflection coefficients, material colors etc, and generating an image, the inverse renderer takes an image and tries to derive the parameters. As they mention in the video, this allows for a lot of interesting usages which you cannot really do in a forward renderer except by brute force.
- jcims 6y agoI wish they tried to make that slab in reality to see if it works.
- CyberDildonics 6y agoThe original paper on computed caustics used a CNC to make acrylic that had the right shapes to create caustic designs in real life. https://chateaunoir.net/caustics.html https://chateaunoir.net/caustics.html https://www.youtube.com/embed/R00IvqcI9jU https://www.youtube.com/embed/R00IvqcI9jU
