[vtkusers] Compute Concave Hull in VTK

[M. Jordan]

Hi,

i would like to compute the concave (not convex!) hull of a vtk polydata surface.
I have a brain model and would like to get a flat surface without furrows.

I tried vtkDelaunay3D with some values for alpha and subsequently a geometry filter to get the surface, but
the result is not that good. (the surface isn't closed and i think that there are some triangles inside the surface).

Is there another method to compute the concave hull?

Thank you!
