Hi Gianni, I never used PositionAttitudeTransform. Try MatrixTransform instead. You can combine different transformation in the final Matrix. Something like:
osg::MatrixTransform* mxt = new osg::MatrixTransform; mxt->setMatrix(osg::Matrix::scale(x,y,z)*osg::Matrix::translate(x,y,z)) Nick On Tue, Oct 29, 2013 at 3:50 PM, Gianni Ambrosio <[email protected]> wrote: > Here I am again ... > > Every moving object is something like this: > > osg::PositionAttitudeTransform (for trasnformations wrt global) > osg::PositionAttitudeTransform (for scaling underlying graphics, not > transformations) > osg::Group (that contains real graphics) > > As suggested, the track map is basically an osgViewer::View with a > osg::PositionAttitudeTransform as scene data.
