[vtkusers] vtkActor - difference between user transform, user matrix, position, and orientation

[Serena Wong]

Hi,

I'm a beginniner at vtk and I wanted to understand the difference between
setting the user transform, the user matrix, and then using the SetPosition
and SetOrientation commands for the vtkActor.  I notice that they all
multiply by each other to achieve a particular result.  Can someone point
me at the right documentation for understanding this better?  What I want
to do is basically I have a number of points or poses and I want to show a
cone an the position and orientation of that particular pose.

Thanks,
Serena
