Deform with control points

Hi there

I tried to find a way to deform a surface by moving control points in grasshopper.

Like the picture below, I scaled up the control points at the top line of the surface toward X, Y axis.

I have no idea how to do it in grasshopper

You’ll need to provide motion vectors for deformation… (14.6 KB)


Thanks a lot!
