More specifically root->getOrCreateStateSet()->setMode(GL_MULTISAMPLE_ARB, osg::StateAttribute::OFF | osg::StateAttribute::PROTECTED | osg::StateAttribute::OVERRIDE); after the viewer has been realized. > 2) I think that number of sample is define when the OpenGL context is > created > so recreate a context on each switch of the number os sample you want. > Why should I recreate a context? I think I should be able to enable/disable Multisampling with setting the state mode ON/OFF. > How did you know that multisample is enabling/disabling. > Did you look the render ? Yep, that is the case.
