+- expression_blendshapes_3448.bin:
+	6 expression blendshapes for the sfm_shape_3448 model. Contains the expressions angry,

+- model_contours.json:
+	Definition of the model's contour vertices of the right and left side of the face.
 
 - reference.obj:
 	The reference 3D shape used to built the model. We make it available so 
 	that new user-defined landmark points can be marked in this lowest-resolution
 	model, if the points exist here.
+	
+- reference_annotated.obj:
+	Visualisation of the landmark points defined in the ibug2did.txt mapping file.
+	* Red: Annotated ibug points that are defined on the reference shape.
+	* Green: Contour vertices from the file model_contours.json.
+	The file ibug2did.txt contains a few more mappings of landmarks that are not present
+	in the reference, for example the middle-inner eyebrow points - they are not visualised.
 
 - reference_symmetry.txt:
 	Contains a list of vertex symmetries of the reference shape, i.e. each
