Sorry, Robert. I had found a solution.  It's a shame for me not to find it. http://forum.openscenegraph.org/viewtopic.php?t=1380&highlight=

There is an another problem. When a group has been added into osgFX::Outline, how to remove outline effect from it's specific child.


Code:

osgFX::Outline *outline = new osgFX::Outline;

osg::Group *group = new osg::Group;
osg::Geode *geode_1 = osg::Geode;
group->addChild(geode_1);
// add more osg::Geode and init drawable for this node.
// ....

// How to remove Outline effect from this node.
// I had tried to remove stencil test. But it failed.
osg::Geode *geode_no_outline = osg::Geode;
// geode_no_outline->getOrCreateStateSet()->setMode(GL_STENCIL_TEST, osg::StateAttribute::OFF);
group->addChild(geode_no_outline);
// init drawable
// ...

outline->addChild(group);


[/code]
