Re: [osg-users] OpenSceneGraph with Qt multiple windowing problem

Hi Robert, thanks for the information about the contexts. Now my task seems to me easier that I thought. I'm subclassing from osgViewer::GraphicsWindow, so I think I'll have to take account for the context IDs and the osg::State, as the osgwxviewer does (though only for one view). Anyways, I

Re: [osg-users] OpenSceneGraph with Qt multiple windowing problem

Hi Arnaud, Viewer and CompositeViewer can both share scenes between them. What you are trying to do is supported, and already works well see the osgcompsiteviewer. The complication in your case is that QT is quite up to scratch for this type of work makes it more awkward - its OpenGL support

Re: [osg-users] OpenSceneGraph with Qt multiple windowing problem

Hi Arnaud, My guess is the context ID's are overlapping for the separate windows, resulting in sharing of texture objects and display lists. I'm not sure though, as I haven't tried this type of thing with QT. Could you modify the osgviewerQT example so that it creates windows/viewers in the

Re: [osg-users] OpenSceneGraph with Qt multiple windowing problem

Hi Arnaud, I'm afraid I like others are very busy so if you can help by providing a modified osgviewerQT that we can easily compile and reproduce the problem then this will really help. Just post source to the osg-users list. Cheers, Robert. On 9/18/07, arnaud houegbelo [EMAIL PROTECTED]
