[vtkusers] Problems using VTK on different graphic boards

[Michael Aschke]

Hi all.

We use VTK for stereoscopic visualization. The stereoscopic images are 
displayed using a TFT-Monitor each. In this setup we use a GeForce 4 
Ti46000 dual graphics board. In order to make changes to the software it 
is planned to  edit the source code of our project on a third monitor 
(via a PCI graphics board (GeForce4)).
We want the PCI graphics board just for the Windows Desktop and leave 
the GeForce 4Ti dual board for VTK.

The graphic boards are configured, so that we have a single Windows 
desktop  including the areas which are displayed by the monitors.

Our Problem is now:
If we start the software on the monitors attached to the dual graphics 
board, the RenderWindow is blank (nothing is visualized), but 
Interactor-Events work fine.
If we start the software on the monitor attached to the PCI graphics 
board (which is the primary monitor), everything works fine.

We suppose this is an OpenGL Problem, because our GUI-Application (Qt) 
is displayed correctly.

Is there any way to tell VTK to run on a specific graphics board if 
there are more than one available?

I hope, someone can help me with this.

best regards,
Michael
