   Caustics Mapping [in OpenGL, CG]
  HiJust wanted to see if anyone had implemented the caustics rendering technique described here:http://graphics.cs.ucf.edu/caustics/They produce some really nice results and achieve very high framerates (pictures and video on their website). It looks like it is conceptually somewhat similar to the shadow mapping technique.I am going to try to implement this using OpenGL and CG, but the paper doesn't really go into implementation details so there are a lot of gaps to fill in. Haven't seen any tutorials for it so far which surprises me.Anyone done this, found tutorials, or come across hurdles in the implementation?-Sveinnp.s. my first post on gamedev .. woohoo :)[Edited by - sveinn on June 1, 2009 2:38:33 AM]
