Take a look at these examples:

http://www.vtk.org/Wiki/VTK/Examples/Cxx#Surface_reconstruction

Particularly the ones that use:
<http://www.vtk.org/Wiki/VTK/Examples/Cxx#Surface_reconstruction>
vtkSurfaceReconstructionFilter<http://www.vtk.org/doc/nightly/html/classvtkSurfaceReconstructionFilter.html>

Let us know how it goes.
