I have generated an Organic mesh from an Archimedean solid using tOpos plug-in.
Now, I am trying to extract a simplified polyline (like a Wireframe) from the Organic mesh to use it in Multipipe component for further remodelling.
Thanks in advance for your time and assistance.
In grasshopper: Mesh edges
In Rhino: Dupedge
Are you looking for the mesh skeleton? There are various methods for this, (eg GCAL have this CGAL 5.2.2 - Triangulated Surface Mesh Skeletonization: User Manual ) however I’m not aware of any implented in grasshopper. One actually involves voronoi I’ve only ever done it in 2D, but it should also work in 3D. In 2D to get the Centerline of a polygon, you sample the perimeter at high density and use these points to create a voronoi diagram. The Centerline will become visible, however you’ll need to remove a lot of extra lines. Most can be filtered by removing duplicated, and checking containment and line|line intersections with the perimeter.
Thank you for your suggestions.
I have tried them, but not really getting what I want.
I will post once I find the solution.
Thank you very much for your suggestion: Mesh Skeleton and introducing me to CGAL.
This is exactly what I was looking for. But still could not figure out how to use it in GH.
The 2nd method you mentioned, can you be more specific? So that I can try it out.
Thank you very much for your suggestion.
Just what I needed.
