[vtkusers] Rendering on very large screens

[Joe Ping-Lin Hsiao]

Hi,

I have tested my VTK program in a room surrounded by eight connected
projectors, which all driven by a Nvidia Quadro card. From Windows 7's
Screen Resolution panel, I see four 3072x768 monitors. My program runs
fine except that if I expand my program window to exceed certain size,
like more than two walls, those parts will get garbage rendering, like
the frame buffer doesn't update.

Another person also having this issue before told me he had to create
two windows and share graphics context between them. He was using
OpenGL and WxWidgets.
I was wondering how I am going to do that with Qt and QVTKWidget.

I also checked the VTK code of sharing camera between QVTKWidgets on
VTK wiki, but the mouse only works on one of the widgets. So rendering
into two separate windows might not be best cause I have mouse
interaction setup. Any suggestion?

Thanks,
Joe
