hello robert, Before snapped the picture and run "osgviewer cow.osg ", already set the NV driver to force antialias and replace all the programm setting,and now just tried following .bat file: cd ./bin osgviewer --window 600 15 800 800 cow.osg --samples 16 pause this is according your suggestion,and the result is still no anti alias effects. we running in windows 7 ultimate x64 version so in these days we tried many different NV 3d cards and different version drivers,and the problem is still! This problem confused us many days,so psot it to maillist! Thanks

Hi Zhuwan, I am not aware of any changes that would introduce a regression in anti-aliasing, perhaps rather than a bug you have confused the set up of aliasing. The OSG by default does not enable anti-aliasing, this applies to 3.2 the same with all previous OSG releases. So running the osgviewer with cow.osg and without the OpenGL driver overrding to switch on anti-aliasing you should see no anti-aliasing in any OSG version. To enable antialising you have to set the Traits::samples and sampleBuffers values when setting up the GraphicsContext. You can set the default via the OSG_MULTI_SAMPLES env var, or via the command line i.e. osgviewer cow.osg --samples 4 I have just tried this on my OSG svn/trunk + Linux/NVidia system and it works just fine. If there has been a difference in behaviour then it'll likely be down to the OpenGL driver playing games with auto-detecting the software that is running and choosing defaults. This does happen, but I haven't heard this happening to osgviewer yet. Robert.

Even in single 3d card mode,and tried many NV 3d display card,still is zigzaged,and the previouse version of osg which is before 3.2 can do anti alias correctly! anyone know why?
