osg学习（六十九）进行平移、旋转和缩放操作

 osg::PositionAttitudeTransform* patTransform=new osg::PositionAttitudeTransform();

    
 patTransform->setPosition(l2wMatrix.getTrans());
    
 patTransform->setAttitude(l2wMatrix.getRotate());
    
 patTransform->setScale(osg::Vec3d(200.0,200.0,200.0));
    
 patTransform->addChild(cowModel);
    
 root->addChild(patTransform);
