Mike ive just finished an animation of a cup of cofffee with the surface
of the coffee rippling. I tryed both displacement map and a bump map
together and seperatly. for my use the diplacment map seemed to take longer
although i didnt watch the render time exactly., but the edges of my coffee
surface seemed to eb and flow (very strange). Both bump and displacement
did take longer to render but acheived an very fifferent effect. But in
the end i opted for straight bump mapped ripples which looked like real
coffee in a cup. I hope this thought helps.
