[Paraview] paraview transformation filter

[haiyan]

Hi,

I'm new to paraview. I'm trying to display two surfaces in 3D view in 
paraview GUI. Two surfaces (.vtk file) are intersected with each other 
and can be displayed correctly using vtk-python script. I put the 
orientation, translation, scale, which are extracted from the 4x4 
transformation matrix, in the 'transformation' window under 'display' in 
'object inspector', and set the origin in the header of the vtk files of 
the two surfaces to '0, 0, 0'. But no luck.

So do I need to construct a pipeline instead? or, paraview calculates 
the orientation and translation from the matrix in a different way 
comparing to vtk (I used the same matrix in vtk.DeepCopy)?

Regards
Helen
