[vtkusers] Multiple renderers in the same top window??? Help!!!

[Yang Wang]

Dear all,

Currently I am using vtkImagePlaneWidget in order to show three 
orthogonal planes
that probing a 3D image dataset.

However, meantime, I need to show these three planes in 2D mode side by 
side below
the 3D view for segmentation operation purposes. So my question is:

(1) How am I being able to do that?
(2) Is it possible to have multiple renderers in the same toplevel 
window or should I use two windows?

Any suggestions or help is welcome.

Thank you.
