Look at depth of field, it works very well for underwater scene, going some way to spoof the blurring in the distance caused by water. I believe there's a nice implementation in the book ShaderX3 As for sun-beams or god-rays check out the book ShaderX5 there's a good article on a multipass technique there A great text on ocean simulation/rendering is Tessendorf's "Simulating Ocean Water" (http://www.finelightvisualtechnology.com/docs/coursenotes2004.pdf <http://www.finelightvisualtechnology.com/docs/coursenotes2004.pdf> ). And this one is good for over/underwater lighting simulations: http://www.cs.utah.edu/vissim/papers/water/ <http://www.cs.utah.edu/vissim/papers/water/> None of these are specific to osg of course but from personal experience I've found the techiques are easily implementable with the OSG. I'd be very interested to see any work you do in this area as it's of particular interest to me. Regards, Kim.

How can I create on OSG? I want to learn more than using a Fog, plankton or bubbles effects. For example, waves, multi-pass particle effect or sun-beam effects? Where should I start? Thanks so much. Best Regards. Ümit Uzun
