<p>Hi,<br>
<br>
i would like to compute the concave (not convex!) hull of a vtk polydata surface.<br>
I have a brain model and would like to get a flat surface without furrows.<br>
<br>
I tried <span>vtkDelaunay3D</span> with some values for alpha and subsequently a geometry filter to get the surface, but
<br>
the result is not that good. (the surface isn't closed and i think that there are some triangles inside the surface).<br>
</p>
<p><br>
Is there another method to compute the concave hull?<br>
<br>
Thank you!<br>
