High level overview
The class diagram shows the Root class of OGRE and all of the Manager classes that gives access to the different subsystems.
- The Root holds a reference to the current SceneManager and to an enumerator that allows other types of scene graphs to be loaded.
- The RenderSystem is an abstract class that separates the Root from the specific implemention of the RenderSystem, OpenGL or Direct3D.
- The ResourceManager is an abstract class that is subclassed by a number of managers that handles resources such as textures, materials and fonts.
- All of the classes in the diagram except for RenderSystem, SceneManager and RenderWindow are using a singleton template to ensure that there is only one instance of each class.
