[osg-users] Antialising

[Voerman, L.]

You still need to enable anti-aliasing for your scenegraph:

if (osg::GraphicsContext* context = camera->getGraphicsContext() {
  unsigned int contextID = context->getState()->getContextID();
  if (osg::isGLExtensionOrVersionSupported(contextID ,
"GL_ARB_multisample",1.3)){
    osg::ref_ptr<osg::StateSet> stateSet =
_sceneGroup->getOrCreateStateSet();
    stateSet->setMode(GL_MULTISAMPLE_ARB, osg::StateAttribute::ON);
  }
}
Regards, Laurens Voerman.
