[vtkusers] Computational Geometry - user equations?

This is my own opinion but in the long run it is probably better to move to
VTK 6.3 at least.
However, having said this you need to evaluate your own code in the light
of: http://www.vtk.org/Wiki/VTK/VTK_6_Migration_Guide and
http://www.vtk.org/Wiki/VTK/VTK_6_Migration/Overview in order to see how
much work will be involved.
VTK 6. was a big change from VTK 5 but there are lots of nice extras in VTK
6.3, such as OpenGL2, QT 5 and VTk 7 (the master) is taking things even
further with Python 3 support, vtkFlyingEdges etc. Also there has been a
lot of work done for other platforms such as Android and IOS.
These links may help:
