Hi, I am not sure what OpenGL method to use for this project that I am involved with. I have created an ocean with waves and need to demonstrate the change of the water levels in different areas in the ocean. If I am given data in meters what do I use? I already have points along the sine graph to show the waves how do I show the water levels increase and decrease? Do I increase the z-coordinates that are the points on the sine graph? Do I use control points with bezier patches? I need help? Laura
