Well, I’m not sure if this should go in the advanced section or not, but I feel like I’m a beginner to opengl.
I’m trying to render an underwater scene, I currently have a terrain - using a heightmap, particles in the water - GL_POINTS, and a pipe with a leak and bubbles coming out of it.
It is written in C++ using MFC and I’m using Visual Studio .Net Environment. I’m hoping to implement Caustics, I found this http://www.opengl.org/developers/code/mjktips/caustics/ on your website but can’t quite get my head around the code. I was wondering/hoping that somebody might help me with this, by explainig the code found on the website mentioned. Or if someone has done this already then could they let me know how.
