[vtkusers] How to get the updated value of a vtkAssembly's position?

[Di Wang]

Dear Users,

I am trying to model a robot arm using vtkAssembly and by which, I could easily simulate the arm motion using AddOrientation(x,y,z). However, one problem is the global coordinates of each part of the arm still keep unchanged (the original value) through the motion. So, are there some easy ways to return the new position & orientation of each part of the arm?

Any suggestion is highly appreciated!
