[osg-users] Setting my ZNear and ZFar clipping planes?
Hi, I'm trying to set up my system so that I can manually specify the clipping planes. In past projects I would use the SceneView object and the SetComputeNearFarMode method. This project I'm not using a SceneView (Just a viewer) and I have no idea how to get at this functionality. (I'm also looking for a way to override the code that creates the left-eye,right-eye matrices.) Thank you!

All the functionality is still there, you just have to follow the composition and inheritance hierarchy. Viewer is-a ViewerBase and an osgViewer::View osgViewer::View is-a osg::View osg::View has-a Camera Camera is-a CullSettings The setComputeNearFar() method is now a part of CullSettings, so: viewer-getCamera()-setComputeNearFar(...) It's a long (and fairly winding) road to travel, but it makes sense once you get there :-) (I'm also looking for a way to override the code that creates the left-eye,right-eye matrices.) A ComputeStereoMatricesCallback in osgUtil::SceneView is probably what you're looking for. You can get to the SceneView object through osgViewer::Renderer (just a different inheritance road to travel). --J ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Robert has indicated that he intends to replace it at some point. This is the only way I could find to handle it right now (though I could certainly be missing something). If you're worried about it going away, you could just create the split view manually using slave cameras. Are you sure you can't get the results you want by using the controls in osg::DisplaySettings and/or osgViewer::View? --J ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
