Thanks, that worked OK. I still have one problem. I see drawing only when drawn straight ahead. If I draw on other locations, I don't see any drawing. It seems that drawing and field of view are somehow out of sync??

Its not too hard to do, the way I have do this is to derive my own node from osg::Drawable and the main function to them create is virtual void drawImplementation( osg::State& state ) const ( there are a few others ) But you do all your opengl in drawImplementation(...) make sure you leave Opengl in the same state you entered otherwise you will screw OSG's state management And in your osg::Drawable constructor call setUseDisplayList(false) otherwise you will only get called once, also you will have to see the bounding box up.. See the OSG examples on creating nodes and simply replace drawable with your custom drawable Works well for us....

The point is, I don't have static geometry, so I would like to render it on my own. thanks _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
