Maybe the viewer is automatically finding your model, so it "looks" like
the model did not move.
Try adding the model twice, once with and once without transform. You
should see two models separated.

Hi:
I try to transform osg::Node by MatrixTransform,but failed .Could
anybody tell me what is the matter.
Here is my code:
osgViewer::Viewer viewer;
osg::Node* node = osgDB::readNodeFile("car/car.osg");
osg::Group* rootNode = new osg::Group;
osg::MatrixTransform* mt1=new osg::MatrixTransform;
mt1->setMatrix(osg::Matrix::translate(osg::Vec3(0.0,0.0f,2.0f)));
mt1->addChild(node);
rootNode->addChild(mt1);
viewer.setSceneData(rootNode);
viewer.realize();
viewer.run();
another problem: can I add matrixtransform to another matrixtransfrom in
order to get the total effect the two matrixtransforms?Should I use
nodevisitor to implement this idea?
