   finding water rendering articles or demos
I want to study how to render water in 3d scene, but i have find less material on this topic.like this: http://www.ogre3d.org/tikiwiki/Hydrax is there any another useful articles or demos?
This is probably overkill for what you want to do, but I'll mention it anyway:http://mmacklin.com/pbf_sig_preprint.pdf;I used this when I was in high school for my water rendering project. It's pretty decent, and has sample code along with the paper. http://fileadmin.cs.lth.se/graphics/theses/projects/projgrid/;What specifically are you interested in? Reflections? Water optics? Wave simulations? I have some articles on my blog:http://mtnphil.wordpress.com/category/water/ Currently I'm working on an article about height field water simulation (waves). This page has links to a lot of articles:http://vterrain.org/Water/;I have a demo that demonstrates water that goes a little bit behind the basics (with that I mean refraction/reflection/fresnel), which you can find it here. I also have a very simple implementation that is just a plane with a color and some scrolling normal maps, which you can find here. You can download the source and/or the demo on the pages. I don't claim these are the best ways to do it (they were made with some tight time constraints), but it got the job done. Hope it's helpfull in some way.
