There is no "easy" way to do interactive oceans and splashing effects, which is
why there's the need for 3rd party specifics such as Arete and Real Wave. If
you intend to do interaction with your surface, then you'll need your vertex
points to move in order to give you reference from which to deform for wakes
and emit particles for splashing.
You can move the points using the waves operators, but they are not well suited
for the amount of randomness you need for an ocean. If you want to go the rout
of generating your waves via textures, you'll need to convert the displacement
maps to shpe animation. There are plugins out there you can find on the various
XSI site that will convert grayscale to vertex v-values, but I'm not sure about
animated ones.
Then you are dealing with an enormous data set, so much of your time will be
spent figuring out ways to cheat the ocean grid resolution into something
manageable. This fact holds true for the third party apps as well, so you'd be
stuck doing this regardless.
Once you have moving points for your wave action, you can use lattice deforms,
and particle effects to get all the interaction you need... displacements,
wakes, foam, etc.

Based on Brads techniques and the ones that i have here, if Iwanted to create a
wake or swell, or even a splash?
