[Camino-users] PARAVIEW visualization issue

[Alessandro Calamuneri]

Hi Michael,
thanks a lot for replaying soon!
I am a bit into troubles for applying the trasformation, because in the
header information I get a 4x4 matrix with the spatial information,
something like
-2 0 0 90
0 2 0 -126
0 0 2 -72

When I get into the transform function within paraview I am asked 3 values
for translation, 3 for rotation and 3 for scaling.
How should I correctly fill out those parameters? To me it is not that clear
Best,
Alessandro
