Traditional plane based modeling and rendering of ocean wave lacks in consider ations on the effect of globe curvature in detail

thus fais to realistically simulate the change of shape

color of the ocean waves on sphere. In this paper

considering sphere shapes influence and free viewpoint

a new method of modeling and rendering of ocean wave is presented. Its kernel is the modeling of ocean waves on sphere and the screen-subdivision algorithm. The ocean wave model based on the knowledge of ocean

analytic geometry and the characters of digital globe is set up first. It reduces the computation obviously and resolves the “compress phenomenon” at high latitude. Then

relying on a procedural ocean wave model

the method restricts computations to the visible part of the ocean surface using the screen-subdivision algorithm and adapts the geometric resolution depending on the viewing distance. The “border slit” on screen can be removed by the “Clamp Sphere”. Finally

the realistic scenes are real-time rendered based on GPU. It allows the user to interactively fly over an unbounded animated ocean.
