 ===== Project graph visitation =====
-To be displayed in the 3d scene, the project graph is visited by a DisplayVisitor (whose most common implementations are WFVisitor for the Wireframe view, and GLVisitor for the OpenGL 1 view). From the root, each Node with a **Successor** or **Branch** edge is visited. All nodes connected with other types of edges are ignored.
+To be displayed in the 3d scene, the project graph is visited by a **DisplayVisitor** (whose most common implementations are WFVisitor for the Wireframe view, and GLVisitor for the OpenGL 1 view). From the root, each Node with a **Successor** or **Branch** edge is visited. All nodes connected with other types of edges are ignored.
 Additionally, to impact the 3d display nodes needs to extends **Null** (de.grogra.imp3d.objects.Null), which represent the Nodes with 3d transformation. Each **Null** object have its own local transformation (could be null).
 The DisplayVisitor goes through Nodes stacking their local transformation. Thus, the global transformation of an Object in the 3d scene, is the combination of all local transformations of all its parents (in the successor/branch sense).
+All GroIMP **module** extends **Null**.
