What are caustics? A caustic is a beautiful phenomenon in nature where curved surfaces reflect or refract light, thereby concentrating it to a relatively small area. This technique makes it possible to essentially imagine any kind of caustic pattern, for instance, this brain pattern, and it will create the model that will cast caustics that look exactly like that. It also works with sunlight, and you can also choose different colors for your caustics. The authors found their simulations to be in good agreement with reality, therefore the desired caustic patterns can be fabricated faithfully. ___________________________ The paper "High-contrast Computational Caustic Design" is available here: http://chateaunoir.net/caustics.html The full Rendering course at the TU Wien is available here: https://www.youtube.com/playlist?list=PLujxSBD-JXgnGmsn7gEyN28P1DnRZG7qi More results from this project are available here: http://rayform.ch/ Subscribe if you would like to see more of these! - http://www.youtube.com/subscription_center?add_user=keeroyz Image credits (all CC-BY): https://en.wikipedia.org/wiki/Caustic_(optics) https://www.flickr.com/photos/fdecomite/2486275725 https://flic.kr/p/pamCiP https://flic.kr/p/nD7Ex https://flic.kr/p/iJUi3 https://flic.kr/p/8DvPiz Splash screen/thumbnail design: Felícia Fehér - http://felicia.hu Károly Zsolnai-Fehér's links: Patreon → https://www.patreon.com/TwoMinutePapers Facebook → https://www.facebook.com/TwoMinutePapers/ Twitter → https://twitter.com/karoly_zsolnai Web → https://cg.tuwien.ac.at/~zsolnai/
