Replacing coordinate values of points to make a warped surface

[René_Corella]

You probably want to study a couple of different things like deformations of the surface via points or using objects. @flokart’s advice is also on point.

For example, look at this discussion. I adjusted an example shared there to exclude the border points as you’re trying to do:

The graph mapper then simply helps with those gradual transitions.

Select the points in grasshopper then manipulate them manually in Rhino via their individual gumballs - alternatively, right-click the point component and establish new attractor points.

Other related examples using curves and grids and stuff - many things out there:

Deform surface with attractor curve, making a surface from points

Hello there, I’m trying to deform a surface with an attractor curve. For that purpose I projected a curve onto the surface and then moved this projected curve away from the surface. I internalized the base surface, the attractor curve and the vector (direction in which I moved the projected curve). Now, for some reason many of the points which result from divide surface are Null. Can someone explain to me why that’s the case? In the end I wanna make a surface out of the attracted points. Bu…
