Hi Antoine, osg::ShapeDrawable was only ever intended for very light usage, quick looks on the shapes, rather than an efficient and flexible basis for rendering geometry. I now regret every writing ShapeDrawable as I have to recommend so often not to use it.
osg::Geometry is not quite so straight forward to use as you'll need to compute the geometry data yourself but it'll be far more flexible and efficient. Cheers, Robert.
