 /**
-Stores data for a complete 3D object.  This includes a mesh, a shader and data
-for it and a number of textures.  Only the mesh is mandatory, other components
-are optional.
+Combines a Mesh with a Technique to give it an appearance.  The Technique will
+define which render passes the Object supports.
 
-See also class ObjectInstance.
+In many cases, it's desirable to include multiple copies of an Object in a
+Scene, with different model matrices.  ObjectInstances can be used to alter the
+rendering of an object on a per-instance basis.
