You're mixing up osg::Drawable::CullCallback and osg::NodeCallback and
consequently
osg::Node::setCullCallback and osg::Drawable::setCullCallback.
osg::Drawable::CullCallback has a virtual cull() function that tells if the
Drawable
*should* be culled by returning true or false.
osg::NodeCallback has a virtual operator() that does what you want.
You need to derive your callback from osg::NodeCallback, implement operator()
(as you
already do), and call:
_mainChild->setCullCallback(...)
instead of
_mainChild->getDrawable(0)->setCullCallback(...)
Hope this helps,
