[Chris Volpe ARA/SED]

Thanks for confirming the issue, Mathieu. Unfortunately, setting the orientation type doesn't work for me (see error below).

I have seen that issue too:

http://www.vtk.org/pipermail/vtk-developers/2008-June/005232.html

This appears after VTK 5.0, so I am using the following trick:

#if VTK_MAJOR_VERSION >= 5 && VTK_MINOR_VERSION > 0
      reader->SetOrientationType( ORIENTATION_BOTLEFT );
#endif
