Hi Robert,
Before trying --samples 16,already tried --samples 4,and the result is the
same,and when double GTX 760 SLI the up limited anti alias level is SLI 64X,so
is not exceeded,the current NV driver version is 320.49 WHQL,The NV driver's
quality is very good,so we never used any ati cards!
thanks

Hi Zhuwan,
I don't user Windows so can't comment on the specifics of this platform, for
this I will have to defer to other Windows users.
The one thing I would add is that you --samples value is excessive, try
reducing it down. Also with the driver try setting it so it allows the
application to set the anti-aliasing setting rather than override it, then run
osgviewer with the command line I suggested.
Robert.

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

主题: Re: [osg-users] This is a new BUG which is introduced by OSG3.2?
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.

Hi all,
I boughted two NV GTX760 4G DDR5 3D cards,and make them SLI
successfully,and also tested many other type 3d cards,seems in OSG 3.2's viewer
window can't do any antalis,the attached snap shot is the NV display set,and
the runtime snap of "osgviewer.exe cow.osg"!
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?
Thanks
