[vtkusers] vtk and coordinates

[Jean-Baptiste Estival]

Hello,

I have an actor A in an assembly AA. Its position (Set/GetPosition) is 
given in the assemby AA x,y,z axis (not world coord).
I have antoher actor b in another assembly BB. Its position 
(Set/GetPosition) is given in the assembly BB x,y,z axis (not world coord).
Now I need to make some computations like outdistance between 
A.GetPosition and B.GetPosition. I just need to have A and B positions 
in the same x,y,z axis : world coordinate.
Can I do this using VTK ? Does anyone know another way to do that ?

Thanks.
Regards

JB
