generative modeling for Rhino
When I take a mesh sphere (sphere meshed by making it in rhino as surface then meshed with rhino command "mesh" without welding etc.) and triangulate it with "triangulate" component, there are some unused vertices - checked with "mesh.vertices.cull unused . This doesnt happen when using "mesh sphere" component only when taking mesh sphere from rhino.
well, this is not really a bug. Every mesh is allowed to take up the vertices it sees fit. However, you can remove the vertices that are unlinked the way you mention. Sometimes unlinked vertices are there for optimization purposes.
I hope this helps,
