-Combines a Mesh with a Technique to give it an appearance.  The Technique will

+Combines a Mesh with a Technique for a complete model.
 
-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.
+An object does not have a model matrix and will be rendered at origin if used
+by itself.  The ObjectInstance class provides a way to position objects in a
+scene and customize them in other ways.
 
-Objects can have multiple levels of detail.  The most detailed level has index
-0, with increasing indices having less detail.  When rendering an instance, the
-instance's get_level_of_detail method is called to determine which LoD to use.

+rendering an instance, the instance's get_level_of_detail method is called to
+determine which LoD to use.
+
+An Object can be rendered with any tag its Technique supports.  Unknown tags
+are silently ignored.
