Water Ripples

What is the most realistic way to make ripples in a pool? (I want ripples to start when the player gets in the water and to spread out.) Note that the ripples will be in a really big pool.

Note that vertex manipulation is SLOOOWW , espacially on larger meshes.

Thanks Stevie! Does anyone know how some of our favorite games do water ripples?

Well, I'm pretty sure oblivion does it with vertex manipulation aswell, but they have a round circle of polygons that go around the player when hes in water so it doesnt have to manipulate a big mesh.

Its pretty obvious as well that they simply use vertex shader which means nearly realtime at no / low cost.

Thanks for your help!
