osg fbx 绘制坐标轴、控制模型影藏与显示

int main()

{

    osg::ref_ptr<osgViewer::Viewer> viewer1 = new osgViewer::Viewer;

    osg::ref_ptr<osg::Group> group1 = new osg::Group;

    osg::ref_ptr<osg::Group> group2 = new osg::Group;

    //osg::ref_ptr<osg::Node> node1 = osgDB::readNodeFile("I:\\BIM\\fbx\\jiaoxuelou20190304.fbx");

    //osg::ref_ptr<osg::Node> node1 = osgDB::readNodeFile("I:\\BIM\\fbx\\Worker201907.fbx");

    //osg::ref_ptr<osg::Node> node1 = osgDB::readNodeFile("I:\\BIM\\fbx\\buildings6.fbx");

    //osg::ref_ptr<osg::Node> node1 = osgDB::readNodeFile("I:\\BIM\\fbx\\wdq.fbx");

    osg::ref_ptr<osg::Node> node1 = osgDB::readNodeFile("I:\\BIM\\fbx\\wall20190707.fbx");

    group1->addChild(node1.get());

    group2->addChild(makeCoordinate(10.0, 10.0, 10.0, ));

    group2->addChild(group1.get());

    //viewer1->setSceneData(group1.get());

    viewer1->setSceneData(group2.get());

    viewer1->setUpViewInWindow(, , , , );

    //遍历节点

    std::cout << "--------------------------------" << std::endl;

    printOsgGroup(group1);

    //BoundVisitor boundVisitor1;

    //group1->accept(boundVisitor1);

    //int nodeChildCount = node1->getNumChildrenRequiringEventTraversal();

    //std::cout << "----count:" <<nodeChildCount<< std::endl;

    viewer1->addEventHandler(new CPickHandler(viewer1));

    return viewer1->run();

}

模型节点控制隐藏于显示，只需要调用  节点的  setNodeMask(1);即可，0：隐藏    1：显示

node->setNodeMask();

//node->setNodeMask(1);
