[vtkusers] Transformations

[Sean Richards]

Hello all,

I am trying to use ICP in my program and I have run into a little glitch.

I create some polydata, then put it through a mapper and then into an actor. The user then manipulates the actor. At this point I want to be able to use ICP to register 2 actors with each other. In order to do this I need to

actor->GetMapper()->GetInput()

the problem is the original input does not move when I move the actor. Does anyone know how to propogate the transformation done with the actor into the original input?
