   Rendering ship's wake effect
  Hi,we have a scenario simulating large water bodies (ocean). We modeled  the ocean surface using FFT. We want the water surface to be interactive, mainly by adding wake effects to the vessel (ship) floating(moving) in the water.We have tried particles systems to simulate wake, but it does not look good. Please sugget us some methods to render such effects. Is there any articles, tutorials related to this.Thanks
