Robert,
I figure what I just did by using horizontal span was similar to
TwinView in Linux. At least I got it to work with the application I
wrote. When I have time, I'll try to find out why osgviewer with
a cfg file that contains one render surface across the two displays
in horizontal span doesn't work on my computer. I'd also like to
find out if Producer::Camera indeed automatically takes into
consideration the situation of a graphics context that spans two
displays, when setLensPerspective(horizAOV, vertAOV, clipNear,
clipFar) is called. Seems like it does.
Cheers,
Yefei
