I have made a paraboloid in a plane:

enter image description here

enter image description here

I would like to control the shape of the top half of the paraboloid (diameter and steepness to the plane), where the paraboloid becomes a sphere and the gap in the plane closes, just like the grey line in this figure:

The movement is similar to blowing a bubble. Is it possible to model this with geometry nodes?

  • $\begingroup$ Tnx for your reply. I've been considering using metaballs, but first I have a plane as base object and not a sphere. Second, GN gives me more control and options than particles. $\endgroup$

Since no one, here is something ...
But no control and you don't need Geometry nodes for such thing at all ...

A trick here here is ...

  • Solidify modifier > Thickness 0.1
  • Remesh modifier > Voxel Size 0.08
