Summary0001629: vtkOBBTree Inside
Descriptionhttp://public.kitware.com/pipermail/vtkusers/2003-May/067563.html [^]
import vtk.*;

// Program to test that vtkOBBTree.InserOrOutside has a bug, because when I create
// some points and test if they are inside a surface, sometimes it says that it is
// true, but if you draw the points then it seems not is true.

 Does the problem still occur with VTK 5.10 ? VTK 6 ?
