thanks drew & francois for the reply...
i had installed evolver earlier, however, i'm quite weak in scripting & vop, 
guess the problem can't be resolved by sop alone.

cheers herman

Just an idea but to avoid any deformation artefact you could use a Vop
Sop and deform your points either with a function based on height if
it's a flat grid or with a Volume Sample and Gradient if it's an
animated geometry.
