One solution is to generate a height field with superimposed sine waves. I
made some include files in the past, and found that the absence of arrays in
POV was quite a nuisance. Now 3.1 is alive, and my example is somewhat
obsolete.

Applied theory comes from ocean engineering. What you  need to specify fro
the sea is the significant wave height and wave period, and some wave
spreading figure. This in formation is used to generate a Bretschneider
energy density spectrum. The latter is used to generate a 20 component wave
height spectrum. These wavelets are then aggregated into the final height
field.  Wave spreading is not developed completely. Now, with arrays, this
could, and will, time permitting, be done.

When you are interested, let me know, and I can mail you the as-is right
away.
