hm, ok, thank you Robert.. but that leads me to another problem:
When I try to link ANY osg-Application against libosgViewer (and that's where StatsHandler is located, isn't it?) the program hangs at start. I can't even produce any output with printf() as the first command in main(). The applicattion simply doesn't start. (I think thats a problem with conflicting libraries.) This ist - as I can see - true for every application linked against libosgViewer even for the OpenSceneGraph/examples. System is: Gentoo Linux 2.6.16, Xorg 7.1 AMD64 (running in 32 bit mode) nVidia 6800 OpenSceneGraph-1.2 CVS version (updated every now and then) I link following libraries against my app: QtCore QtOpenGL osg osgGA osgProducer osgViewer does anyone experience similar problems with osgViewer? thx Frans 2007/2/8, Robert Osfield <[EMAIL PROTECTED]>:
Hi Frans, It doesn't look like anything in your scene will push the cpu usage up when zooming out, its a tiny scene so should tax the system very little. Is vysnc on? I believe this should be on by default for OSX, perhaps Stephan Huber can clarify. The other things you could look at is adding the StatsHandler to your scene to see what is consuming the time. See the application/osgvierwer/osgviewer.cpp to see how it adds the various event handlers to add capabilities to your viewer. Robert.
