Hello, I'm not sure about the problem you are talking about, but just give a suggestion that might help. Maybe the slave camera cache its size, the cache does not update with the Viewport change, and then the intersection takes the data from the cache? You could try to clear the cache and see if the problem continues. And of course maybe it has nothing to do with it, and then I apologize for wasting your time.

In my case, I was not getting correct results from computeIntersections() whenever CompositeViewer was using a single view with slave cameras - no resizing at all involved, just using setUpViewAcrossAllScreens(). You'll have to dig further. I suggest you try starting with a breakpoint in Viewer/CompositeViewer::eventTraversal() (depending on the viewer type you use) and compare the behavior before and after resizing the viewport. Good luck, J-S -- ______________________________________________________ Jean-Sebastien Guay [EMAIL PROTECTED] http://www.cm-labs.com/ http://whitestar02.webhop.org/ _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.or g _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
