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.
