3D Grid Distortion

Hello people...

I have a 2d Grid that its been manipulated by some attractor points, however this is happening both in x and y direction. How Can I make the distortion to happen in the Z direcction as well, As if my attractors points were bubles rather than circles and my grid lines would move around them in all 3 directions.... X,Y,Z

Take a look at the jpeg and the gh definition. Any ideas for it to become a rd grid....?

Thanks

hi igor,

is it possible to create a similiar parametric attractor for a cylinder?
i try something, but it is not so good.

thanks

fantastic work igor!

thank you very much. one question more!
is it also possible, that the deformation happen just to the face normals.
so that the shape of the cylinder does not change,
but the isocurve on the surfaces-normal become deformed.

i think that the deformation could be (maybe) similar to michael works:

but for the cylinder.
i think you can do it. ;-)

thanks

so similar to the possibility in maya,

to move vertex along the u or v direction.
