Re: [osg-users] You have three guess...

That's my question too. Such capabilities are quite cool but seems far away from the name OpenSceneGraph... Are we going to see OSG based operation system eventually? On Mon, Nov 17, 2008 at 1:03 PM, Ed [EMAIL PROTECTED] wrote: I may sound ignorant by asking this, but it won't be the first

[osg-users] OSG on overlapping screen wall

Hello, I am using OSG with a overlapping screen wall (two projecters overlapped to create a large display). A problem is that osgViewer won't use all display area: Two projectors display two sub-screens overlapping together for a large screen. But osgViewer only use one sub-screen. I have tried to

[osg-users] scene update

Hi, just a simple question. Is there any pre-draw-callback function in osgViewer available so that I can update my scene at the beginning of each frame? Is the setPreDrawCallback in osg::Camera the right place to do scene update? What if I have multiple cameras but just want to udpate scene only

Re: [osg-users] How to integrate osg and VTK?

If you could get current GL content then you could just call VTK rendering modules to draw on screen. Or you could extract geometry information from vtkPolyData and draw it use OSG. On Tue, Apr 15, 2008 at 9:25 PM, playzj [EMAIL PROTECTED] wrote: hi All, Who can tell me how to

[osg-users] OSG-2.2 osgViewer-frame() access violation

Hello, don't know whether this has been reported or not. In OSG-2.2, osgViewer-frame() get access violation if there is no data in scene (didn't call setSceneData()). This doesn't happen in OSG-2.0. Do I must give something to osgViewer, even an empty Geode, before I can call osgViewer-frame()?
