In the pvx file, I put the CAVE coordinates in the tracker space, because
TrackerTransform of vtkVRPNConnection did not work properly (strange
behaviour). Maybe the matrix I put in it was wrong...

Thanks for the link to the article. I already (quikcly) read it, but I
missed some things. These day I'm working hard trying to understand how to
extend ParaView, and today an other fight was to dynamically create a slice
cut of an object by plug-in code, still trying hehe... (I think I will soon
post an other thread with that subject :p)

Thanks for your answer !

All the best,

Jean-Noël
