[vtkusers] How to manipulate planes in VTK without using a planeWidget

[Michael Hanley]

Hi all,

First time poster and still a novice with vtk, so excuse my terminology.

Basically, I have two cutting planes acting on a 3d object. One plane is 
linked to a planewidget, so moving the widget moves this cutter plane 
along the object in sagittal/axial/Coronal planes. The other cutterplane 
is a parallel plane to the first cutter plane, any instance of this 
plane is simply called to the current location of the first cutter 
plane, it is not movable with the widget.

So, what i want to do is to be able to call these planes to specific 
locations in space, namely discrete points along the 3d actors surface 
without using the planewidget. So is there a command in VTK (i use Tcl) 
that will let me do this? AddPosition was recommended by a friend, but 
this only moves the actor, the plane still acts on the same point on the 
3d object.

Thanks
