Simulation of shallow water based on shader

We introduce a method for simulate and render of ocean wave by vertex and fragment processing. The method is divided into four stages: wave generation, surface tessellation, optical simulation, and water surface rendering. Our implement not only is a simple wave by influence of terrain like previous work, but also a manipulative model by influence of the wind that are well suited for simulate all kinds of wave in shallow water. Rendering makes use of Cg shading language on consumer-level GPU to allow for a representation of reflection, refraction of light. We are satisfied with the result from implementing the respective stage's shader.
