Re: [osg-users] 3D Scene emulating a 2D environment

theoribeiro: Just set your ortho projection values to your screen size: (0, 1024, 0, 768) or whatever. Also set your camera viewport: camera-setViewport(0, 0, 1024, 768). Now the OSG units correspond to pixels on your screen. -- Read this topic online here:

Hi Vincent osg::nofify is a simple log system with only one logger. So you can't expect have many logger or one logger per thread. To do this, you need a strongest log library like log4cpphttp://log4cpp.sourceforge.net/, or the incoming Boost.Log http://sourceforge.net/projects/boost-log/.

Re: [osg-users] Intersection with a boundingBox

Hi Aerkis, There is a osgUtil::PlaneIntersector that gives you the intersection polygon between a plane and a scene, there is also the PolytopIntersector but this tells you whether the scene contains any geometry that has at least part of it in the polytop - it doesn't give the intersection.

Re: [osg-users] Intersection with a boundingBox

Hi Aerkis, all the intersection routines you find under osgUtil are meant just to find intersection (picking being the most common usage), not to clip polygons. For that purpose you should instead look at osg::ClipPlane/ClipNode which implement GL clipping. I don't think there's a routine which
