[Insight-users] check is point inside a closed surface or not

[Cagatay Bilgin]

I remember using vtkImplicitPolyDataDistance for a similar task
http://www.cmake.org/Wiki/VTK/Examples/Cxx/PolyData/ImplicitPolyDataDistance
but if all you care is IsInside rather than the signed distance, there
might be a faster
way. Perhaps someone from the vtk mailing list could provide some help.

Cheers,
Cagatay
