struct MyCullCallback : public osg::NodeCallback
{
void operator()(osg::Node* node, osg::NodeVisitor* nv)
{
osgUtil::CullVisitor* cv = nv->asCullVisitor();
//osgUtil::CullVisitor* cv =
dynamic_cast<osgUtil::CullVisitor*>(nv);
if (cv && cv->isCulled(node))
{
}
}
};
node->setCullCallback(new MyCullCallback);
