[osg-users] Trying To obtain all statsets in a Graph

[Ragnar Hammarqvist]

Hi All osg Users

I'm using a visitor to obtain all Statsets in a graph. But the visitor dose not 
collects all statsets, why?

Code im using is simply this:

        class GetStatsetsVissitor : public osg::NodeVisitor
        {
                
                public:
                        GetStatsetsVissitor(){
                                
setTraversalMode(osg::NodeVisitor::TRAVERSE_ALL_CHILDREN);
                        };
                        ~GetStatsetsVissitor(){};
                        typedef std::set<osg::ref_ptr<osg::StateSet>> 
StatsetSet;
                        StatsetSet& GetStatset(void){return m_Statsets;};
                        
                protected:
                        void apply(osg::Node &n)
                        {
                                if(n.getStateSet())
                                {
                                        m_Statsets.insert(n.getStateSet());
                                }
                                traverse(n);
                        };
                        StatsetSet m_Statsets;
        };
