I concur with Bryan. You appear to be confused by the fact that the osgGA camera manipulators center on the bounding box of the scene graph, and you mistakenly believe that your scene is getting translated instead.
To demonstrate what's happening, I suggest you run the following: osgviewer axes.osg <yourmodel> axes.osg shows the location of the world coordinate origin. If I've misunderstood you, please clarify.

Hi, Lets say I have a MatrixTransform like: Code: osg::MatrixTransform* sceneTransform = new osg::MatrixTransform(); and I apply this matrix to it: Code: osg::Matrix zScale = osg::Matrix::scale(0.5f, 1.0f, 1.0f); sceneTransform->setMatrix(zScale); If I add another MatrixTransform to this first MatrixTransform: Code: osg::MatrixTransform* panel = new osg::MatrixTransform(); sceneTransform->addChild(panel); and apply this matrix to this second MatrixTransform: Code: osg::Matrix zTrans = osg::Matrix::translate(2.0f, 0.0f, 0.0f); panel->setMatrix(zTrans); because the second matrixTransform has been translated beyond the boundaries(scale) of the first MatrixTransform as in the scale is 0.5f and the translate is 2.0f, they both automatically gets translated so the 2 matrixTransforms are centered between the first matrixTransforms parent(what ever that is.) Is there a way so if the second matrixTransform is beyond the boundaries of the first MatrixTransform no automatic translation to center happens? I hope you understand what I am after? Cheers...
