Thanks for the suggestion Sebastien, but I did try looking at both the
UserMatrix and the UserTransform but they both seem to be NULL:

I just added this code to the original link for verification:

	vtkMatrix4x4* userMatrix = this->CubeActor->GetUserMatrix();
	if(userMatrix)
	  {
	  std::cout << "Has userMatrix" << std::endl;
	  }
	else
	  {
	  std::cout << "No userMatrix!" << std::endl;
	  }
	
	vtkLinearTransform* userTransform =
           this->CubeActor->GetUserTransform();
	if(userTransform)
	  {
	  std::cout << "Has userTransform" << std::endl;
	  }
	else
	  {
	  std::cout << "No userTransform!" << std::endl;
	  }

It outputs:

No userMatrix!
No userTransform!

Any other thoughts?
