代码实现如下：

void COSGObject::addAirport()
{
    csn = new osg::CoordinateSystemNode;
    csn->setEllipsoidModel(new osg::EllipsoidModel());

    airport = osgDB::readNodeFile("D:/Project/OSG/bili35/builder/data/Module/airport.ive");

	airport->getOrCreateStateSet()->setMode(GL_RESCALE_NORMAL, osg::StateAttribute::ON);//给obj增加法线 不加就黑色物体
	airport->getOrCreateStateSet()->setMode(GL_LIGHTING, osg::StateAttribute::ON);
	airport->getOrCreateStateSet()->setMode(GL_LIGHT0, osg::StateAttribute::ON);
	airport->getOrCreateStateSet()->setMode(GL_LIGHT1, osg::StateAttribute::ON);

    mtAirport = new osg::MatrixTransform;
    mtAirport->addChild(airport);
    mRoot->addChild(mtAirport);

    osg::Matrixd mtT
