Hi Anthony, ShapeDrawable supports the Drawable::accept(PrimitiveFunctor&) interface so you can implement your own custom PrimitiveFunctor to get access to the vertex and primitive data. You can even use the TriangleFunctor that subclasses from PrimitiveFunctor and breaks the primitives all down into triangles. The src/osgUtil/LineSegmentIntersector.cpp is a example of this in action.
However, I'm not sure why you don't just access the heightfield directly and infer your own triangles from it. You don't say anything about what you want to do with the triangles so I really can't say much about what route would be best. Robert.
