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...
