Public Methods

Method	Description
AddMovableObjectFactory ( MovableObjectFactory fact, bool overrideExisting ) : void	Register a new MovableObjectFactory which will create new MovableObject instances of a particular type, as identified by the Type property. Plugin creators can create subclasses of MovableObjectFactory which construct custom subclasses of MovableObject for insertion in the scene. This is the primary way that plugins can make custom objects available.
AddSceneManagerFactory ( SceneManagerFactory factory ) : void	Registers a new SceneManagerFactory, a factory object for creating instances of specific SceneManagers. Plugins should call this to register as new SceneManager providers.
ConvertColor ( ColorEx color ) : int	Asks the current API to convert an instance of ColorEx to a 4 byte packed int value the way it would expect it.
CreateRenderWindow ( string name, int width, int height, bool isFullScreen ) : Axiom.Graphics.RenderWindow	Overloaded method.
CreateRenderWindow ( string name, int width, int height, bool isFullscreen, NamedParameterList miscParams ) : Axiom.Graphics.RenderWindow	A collection of addition render system specific options.
CreateSceneManager ( SceneType sceneType ) : SceneManager	Creates a SceneManager instance based on scene type support. Creates an instance of a SceneManager which supports the scene types identified in the parameter. If more than one type of SceneManager has been registered as handling that combination of scene types, in instance of the last one registered is returned.
CreateSceneManager ( SceneType sceneType, string instanceName ) : SceneManager	Creates a SceneManager instance based on scene type support. Creates an instance of a SceneManager which supports the scene types identified in the parameter. If more than one type of SceneManager has been registered as handling that combination of scene types, in instance of the last one registered is returned.
CreateSceneManager ( string typeName ) : SceneManager	Creates a SceneManager instance of a given type. You can use this method to create a SceneManager instance of a given specific type. You may know this type already, or you may have discovered it by looking at the results from Root.GetSceneManagerMetaData.
CreateSceneManager ( string typeName, string instanceName ) : SceneManager	Creates a SceneManager instance of a given type. You can use this method to create a SceneManager instance of a given specific type. You may know this type already, or you may have discovered it by looking at the results from Root.GetSceneManagerMetaData.
DestroySceneManager ( SceneManager instance ) : void	Destroys an instance of a SceneManager.
DetachRenderTarget ( RenderTarget target ) : void
Dispose ( ) : void	Called to shutdown the engine and dispose of all it's resources.

GetSceneManager ( string instanceName ) : SceneManager	Gets an existing SceneManager instance that has already been created, identified by the instance name.
GetSceneManagerMetaData ( string typeName ) : SceneManagerMetaData	Gets more information about a given type of SceneManager. The metadata returned tells you a few things about a given type of SceneManager, which can be created using a factory that has been registered already.
HasMovableObjectFactory ( string typeName ) : bool	Checks whether a factory is registered for a given MovableObject type
Initialize ( bool autoCreateWindow ) : Axiom.Graphics.RenderWindow	Initializes the renderer. This method can only be called after a renderer has been selected with Root.RenderSystem, and it will initialize the selected rendering system ready for use.
Initialize ( bool autoCreateWindow, string windowTitle ) : Axiom.Graphics.RenderWindow	Initializes the renderer. This method can only be called after a renderer has been selected with Root.RenderSystem, and it will initialize the selected rendering system ready for use.

OnFrameEnded ( ) : bool	Method for raising frame ended events. This method is only for internal use when you use the built-in rendering loop (Root.StartRendering). However, if you run your own rendering loop then you should call this method to ensure that FrameEvent handlers are notified of frame events; processes like texture animation and particle systems rely on this. This method calculates the frame timing information for you based on the elapsed time. If you want to specify elapsed times yourself you should call the other version of this method which takes event details as a parameter.
OnFrameEnded ( FrameEventArgs e ) : bool	Method for raising frame ended events. This method is only for internal use when you use the built-in rendering loop (Root.StartRendering). However, if you run your own rendering loop then you should call this method to ensure that FrameEvent handlers are notified of frame events; processes like texture animation and particle systems rely on this. This method takes an event object as a parameter, so you can specify the times yourself. If you are happy for the engine to automatically calculate the frame time for you, then call the other version of this method with no parameters.
OnFrameRenderingQueued ( ) : bool	Method for raising frame rendering queued events. This method is only for internal use when you use the built-in rendering loop (Root.StartRendering). However, if you run your own rendering loop then you you may want to call this method too, although nothing in Axiom relies on this particular event. Really if you're running your own rendering loop at this level of detail then you can get the same effect as doing your updates in a OnFrameRenderingQueued event by just calling with the 'swapBuffers' option set to false.
OnFrameRenderingQueued ( FrameEventArgs e ) : bool	Method for raising frame rendering queued events. This method is only for internal use when you use the built-in rendering loop (Root.StartRendering). However, if you run your own rendering loop then you you may want to call this method too, although nothing in Axiom relies on this particular event. Really if you're running your own rendering loop at this level of detail then you can get the same effect as doing your updates in a OnFrameRenderingQueued event by just calling with the 'swapBuffers' option set to false.
OnFrameStarted ( ) : bool	Method for raising frame started events. This method is only for internal use when you use the built-in rendering loop (Root.StartRendering). However, if you run your own rendering loop then you should call this method to ensure that FrameEvent handlers are notified of frame events; processes like texture animation and particle systems rely on this. This method calculates the frame timing information for you based on the elapsed time. If you want to specify elapsed times yourself you should call the other version of this method which takes event details as a parameter.

QueueEndRendering ( ) : void	Requests that the rendering engine shutdown at the beginning of the next frame.
RemoveMovableObjectFactory ( MovableObjectFactory fact ) : void	Removes a previously registered MovableObjectFactory. All instances of objects created by this factory will be destroyed before removing the factory (by calling back the factories 'DestroyInstance' method). The plugin writer is responsible for actually destroying the factory.
RemoveSceneManagerFactory ( SceneManagerFactory factory ) : void	Unregisters a SceneManagerFactory.
RenderOneFrame ( ) : bool	Renders one frame. Updates all the render targets automatically and then returns, raising frame events before and after.
Root ( ) : System	Constructor. This public contructor is intended for the user to decide when the Root object gets instantiated. This is a critical step in preparing the engine for use.
Root ( string logFilename ) : System	Constructor. This public contructor is intended for the user to decide when the Root object gets instantiated. This is a critical step in preparing the engine for use.
Shutdown ( ) : void	Shuts down the engine and unloads plugins.
StartRendering ( ) : void	Starts the default rendering loop.
UpdateAllRenderTargets ( ) : bool	Internal method used for updating all RenderTarget objects (windows, renderable textures etc) which are set to auto-update. You don't need to use this method if you're using Axiom's own internal rendering loop (Root.StartRendering). If you're running your own loop you may wish to call it to update all the render targets which are set to auto update (RenderTarget.IsAutoUpdated).
