[vtkusers] wxVTKWindow: controlling events.

[David Gobbi]

Hi Stefano,

Neither VTK/Wrapping/Python/wxVTKRenderWindow.py (the one I wrote) or
wxPython/lib/vtk.py (the one Robin/Prabhu/Sebastien wrote) has any
binding for the "3" key.

Did you connect a vtkRenderWindowInteractor to your vtkRenderWindow?
If so, then that is what is causing your problems.

As for 3D stereo rendering, every video card and every driver acts
slightly different.  A good driver can render a 3D stereo window and
2D windows at the same time without problems.  With other drivers it
is necessary to convert all windows/renderers to 3D stereo but just
set the EyeAngle to zero in the ones that you want to be 2D.  Some
drivers can only handle a single 3D stereo context.  Some drivers
require the machine to be rebooted every time you switch from stereo
to non-stereo.  And then sometimes the batteries in those stupid
3D goggles go dead, and your client has been politely "ooing" and "aahing"
even though he's seeing double instead of seeing stereo.  Stereo is the
bane of my existence...
