I am trying to achieve an eccentric grid shell geometry. The idea was applying the component MagnetSnap.
The component affects, but somehow doesn’t works smoothly. As shown they kinks out on surface.
What I am expecting should looks like Fig below: An eccentric dome, where has the most of density, and then it decreases to outside. The it is still able to shift this center to anywhere.
Basically, like tree ring.
Do you want to change the actual shape of the surface, or only of the grid on it (while keeping the underlying surface fixed)?
If the latter, I recommend form finding the dome, then use the output mesh from that in a separate process as the target for an OnMesh goal with a new grid.
I wouldn’t recommend using MagnetSnap here, since that increases sharply in strength closer to the target point.
What could be better would be to assign spring strengths based on a smooth field.
Pulling part of the grid tighter during the catenary form-finding will result in that part of the shape being less free to move upwards so you’ll get a big dip there like this:
