26 Stores a Mesh together with a Technique to determine its appearance.
28 It is possible to use a single Object for rendering multiple identical or
29 similar objects. See class ObjectInstance.

61 Renders the object. A tag can be provided to render a non-default pass.
63 virtual void render(const Tag &tag=Tag()) const;
66 Renders the object with an instance. The instance's hook functions are
67 called before and after drawing the mesh. A tag may also be given to render
70 virtual void render(const ObjectInstance &, const Tag &tag=Tag()) const;
73 Renders multiple instances of the object in one go. This may improve
74 performance, as the object-specific render setup only has to be done once.
75 Each instance's hook functions will be called before and after drawing the
78 template<typename Iter>
79 void render(Iter begin, Iter end, const Tag &tag=Tag()) const
