This covers only the rendering of the shadow maps (actual use still needs to be implemented). Working with orthographic projection matrices is surprisingly difficult, partly because creating one includes the translations needed to get the scene into the view (and depth range), which means care needs to be taken with the view (camera) matrix in order to avoid double-translating depending on just how the orthographic matrix is set up (if it's set up to focus on the origin, then the camera matrix will need translation, otherwise the camera matrix needs to avoid translation).
