Hi Paul, Only in git master and recent 3.5.x dev series does ShapeDrawable subclass from osg::Geometry. For older releases (3.4.0 and before) ShapeDrawable computes the coordinates on the fly so there isn't any coords you can get and modify.
As a general note, ShapeDrawable is a convenience class for visualizing shapes in a very basic way, it's not a general purpose tool. Robert.
