[vtkusers] Interact with one of the actors

[Jim]

Hi Goodwin,
 
Thanks for your advice. I added these two lines of code to the TCL example 
VTK\Rendering\Testing\Tcl\pickCells.tcl
 
vtkInteractorStyleTrackballActor irenstyle
  iren SetInteractorStyle irenstyle

It worked great! I can control each actor independently. The only problem is that all 
manipulation is limited inside the same Z depth buffer. It seems to me that I can not change 
the depth order of the actors. Thank you.
 
Jim

Hi Jim,

To drag vtkActors around (independently of each other) use
vtkInteractorStyleTrackballActor as the interactor style.

Dear vtkusers,

To make my question clearer, I found an example which is similar to my
request:

VTK\Rendering\Testing\Tcl\pickCells.tcl

It seems to me that picking a cell is not a problem. How can I pick and then
drag a cell
around? Thanks. Jim.

Dear VTKUSERS,

I have multiple actors added to the same renderer. Is is possilbe to pick or
select any of the
actors AND drag it around with VTK? The default behavior is to
rotate/zoom/pan all actors
at the same time, but I want to interact with only one of the actors.
Someone please point me
to the right direction or a link to an example? Thanks a bunch.

Jim
