   About Realistic Water Rendering
  I'm beginner of shading language.I started learning CG several weeks ago.And the biggest motive I have is the disire to render the realistic water surface,the kind with both relection and refraction,u know~In fact I am working on an assignment,in which I've already successfully simulated ripples and droplets.But it looks really lame cuz my surface is rendered with a common plane with blue-colored lighting..no any Shader is used..So I really wanna improve that surface..I've done some research and now I have the basic idea of using the reflection map and refraction map.I saw the nVidia SDK samples too(which I think is very cool).But I still find it a little hard for me to understand.....Can u guys help me,give me some tutorials with detailed notation,if there are.Or help me with some suggestion,any website,resource,or sample or tremendously help...Thanks a lot!!!   
This one got me started :)
