high i want to create water for a strategy game how ever this game can zoom in alot.. I know bf2 uses vertex shaders for the water and i wanted 2 know if any1 knows of an article or tutorial on this verything... thanks Regards Dawid Joubert

The water in bf2 is more likely made with fragment shaders(but vertex shaders where used to).

this place contains basic tutorials on how to use glsl shaders
http://www.clockworkcoders.com/oglsl/index.html
then go to nvidias developer pages, there are some papers there that could make things more clear.
Finaly google everything(i know this one is a bit clishé) related to this, you might not find actual code, but it will help you on the way.
When this is done, it shouldn't be too hard to work out how to do realisticish water.
