Tensile membrane with in and outwards alternating pressure points

Grasshopper Kangaroo

I’m looking into creating something like this picture right here using kangaroo to apply pressure points going outwards and inwards

However, for some reason all my attempts, though very initial, result in a messy and kinda collapsed mesh
I’m attempting to apply the logic in an ellipsoid shape and

I tried to use intercalated points to pull the mesh to towards them using SolidPointCollide while they’re kept fixed using Anchor.

If someone has an idea on how to solve this, any help would be much appreciated

Hi! think you should be able to just use the anchors for this without the SolidPointCollide constraint.

You can keep the target positions for the anchors the way you set it up but set the inital anchor location to some of your mesh’s vertices (e.g. the closest to the anchor’s target) to pull them in/out towards the anchors.

I think with some more tweaking to the anchor spacing and mesh resolution you could get pretty close to what you want:

Here’s the modified skript. I hope that helps!
