[Paraview] Different Coordinate systems!

[Jérôme]

Hi,

Concerning coordinate systems, the visualization pipeline is what is of
interest for you. You won't find useful stuff in ParaView sources (well,
except for some helper classes or wrap-around VTK) but instead you should
take a look at VTK sources. There, you will find a vtkCamera class and
vtkTransform filters, but also coordinate systems correspondances in
vtkRenderer, vtkMapper, ... ie everything that has role in the visualization
pipeline.

Sorry for the lack of precisions, but I hope that'll help...
