Correct, it works more like the first type of displace warp (which 
actually may be a more efficient way of doing it...), pushing the 
surface in a direction depending only on it's position.
I'm not sure what you mean by "displacing a surface by a specific and 
detailed 3D solid pattern", could you explain what you want?

Maybe another type of displace warp, using the gradient to determine the 
direction of displacement, and another pattern to define the amount of 
displacement. Also, the ability to use a spline as a "float_map" instead 
of a pigment.
