I’m looking for a grasshopper plugin that has a pathfinding algorithms that works in 3d. For instance, it should allow me to find the shortest path between 2 points in a solid object, through the object.

I was checking Galapagos but apparently its pathfinding only works on a surface.

I’m also open to any other ways of doing aside grasshopper if that’s the case, like coding it in.

Hello
I am quite sure part of the solution is some geodesic path. Some others part must be straight line inside the solid.
I made a tool with Geodesic paths on mesh in Nautilus plugin.
But perhaps it could involve Kangaroo. with a curve made with strings.

Hi @Roberto_Neto,
That was a really fun problem thank you for sharing it.
Let me know if the plugin works as intended.

It will find the shortest path inside a solid, the depth of the GRID can be increased. ShortestPath.rhp (11 KB)
In case you need a more advanced version you can always reach out to me via email at farouk.serragedine@gmail.com
Hope this helps,
