Hello Heiko,
When I call:
Code:
_viewer.setUpViewInWindow( 100, 100, 1024, 768 );
osg::DisplaySettings::instance()->setNumMultiSamples(4);
it don't works. But if I use
Code:
osg::DisplaySettings::instance()->setNumMultiSamples(4);
_viewer.setUpViewInWindow( 100, 100, 1024, 768 );
it works. But why? Or is it a bug?
It's not a bug. Look at the code to
osgViewer::View::setUpViewInWindow(...) and think about it. That method
uses the osg::DisplaySettings to do its setup. But once the
GraphicsContext is created using those settings, it won't take into
account the fact that you've changed the settings... So if you set the
multisampling before the creation of the GraphicsContext, it takes
effect, but if you set it after, it doesn't.
If you want it to be visible whenever you set the multisampling on
DisplaySettings, you'll have to manually recreate your GraphicsContexts
(you can call setUpViewInWindow(...) again). This may have some other
effects though (your models may lose their textures if you had enabled
autoUnRefAfterApply, for example - search the archives for solutions to
that).
Hope this helps,
J-S
