[Insight-users] Skeleton or medial axis transform of 3D Mesh

[Karthik Krishnan]

No, there isn't.

However you may wish to check out VMTK (www.vmtk.org). Its based on VTK and
ITK and you should be able to generate the medial axis of a 3D point set
using this. Now, the method is restricted to applications in vascular
analysis etc, in that its restricted to single branch of a vessel, since it
requires you to define the starting and ending point of the medial line. It
then runs fast marching on the voronoi faces of the delaunay 3D tessellation
of your point set to generate the medial line. The mesh connectivity/
topology is ignored. For a dense enough mesh, this should not matter.

You'll need python and linux.
