Re: [osg-users] Using osgViewer::Viewer with independant slave cameras
Thanks for pointing me to the example, Robert. That helped. Obviously, I was too blind to see the part in the example.

[osg-users] Using osgViewer::Viewer with independant slave cameras
Hi! I've search the archives, but could not find any posts on this topic. I want to setup a osgViewer::Viewer with 4 cameras, which can be controlled independently from the master camera, if the user click-drags in the corresponding viewport. Creating the viewer and 4 slaves is not a problem, but to manipulate each cam separately. I have an implementation of my project with the composite viewer, which works, but due to some technical implications, I want to switch to a single viewer. I tried to set setAllowEventFocus(true) to the master and slave cams, but that did not work. Can anybody give me a hint on how to setup the viewer correctly or point me to an example where this is done?

Hi Casten, If you have 4 independent views then you should use the CompositeViewer class. osgViewer::Viewer is for a single View. See the osgcomposite viewer example. Robert.

Re: [osg-users] Using osgViewer::Viewer with independant slave cameras
Hi Robert, Yes, that's what I did first. But unfortunately my 4 views have to be embededded in windows (derived from CDocuemntView on Windows). Creating a view for each window also creates a new graphics context, since each view has its own window handle. Therefore much memory is consumed, which blows my app, if I load a bigger scene (~250k polys, on a Quadro 580FX). Any idea on how I could convince each view of a composite viewer to share the graphics context?
