Re: [osg-users] Hi, Robert, Already find the reason of why OSG3.2 not anti aliased in win7 x64 && GTX 760 4G DDR5 SLI
Hello, Zhuwan, I believe that FXAA is a "quick-and-dirty" antialiasing method used by the Nvidia driver to provide something like antialiasing for less computational cost. See here: http://www.kotaku.com.au/2011/12/what-is-fxaa/ Quote: "FXAA stands for Fast Approximate Anti-Aliasing, and it’s an even more clever hack than MSAA, because it *ignores polygons and line edges*, and simply analyses the pixels on the screen" (emphasis mine) Regards, Jan On Thu, Sep 12, 2013 at 3:23 PM, webmaster wrote: >After many times testing and trying,finally find in GTX760 Nvidia's > driver just like other previouse hardware versions,in the hardware driver's > early version the FXAA option conflicted with normal anti alias settings,if > FXAA is on,and the normal anti alias is also set on,then in fact not anti > alias is doing,so only turn off fever FXAA,then all is OK,and in SLI MODE > the 64x anti alias is very very beautiful! > In other conditions will also caused the anti alias is not working,but we > have no time to deep explore the reasons! > > zhuwan > > > ___ > osg-users mailing list > osg-users@lists.openscenegraph.org > http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org > ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] Hi, Robert, Already find the reason of why OSG3.2 not anti aliased in win7 x64 && GTX 760 4G DDR5 SLI
After many times testing and trying,finally find in GTX760 Nvidia's driver just like other previouse hardware versions,in the hardware driver's early version the FXAA option conflicted with normal anti alias settings,if FXAA is on,and the normal anti alias is also set on,then in fact not anti alias is doing,so only turn off fever FXAA,then all is OK,and in SLI MODE the 64x anti alias is very very beautiful! In other conditions will also caused the anti alias is not working,but we have no time to deep explore the reasons! zhuwan ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
