hi all,
How to make a solid model by a surface mesh?

I use vtkSurfaceReconstructionFilter and some related filters to generate surface from point cloud, the result looks like a crust, now i want t add a bottom to the crust to construct a solid model.

one purpose  of doing this is to compute the volume of convave polyhedra, i try alpha shapes by delaunay triangulation ( the vtkDelaunay3D output is convex hull if not assign an alpha value), but  vtkMassProperties can't get the precise volume.
