Detailed Description

Visitor object that can be used to iterate over a collection of Renderable instances abstractly.

Remarks:: Different scene objects use Renderable differently; some will have a single Renderable, others will have many. This visitor interface allows classes using Renderable to expose a clean way for external code to get access to the contained Renderable instance(s) that it will eventually add to the render queue.

: To actually have this method called, you have to call a method on the class containing the Renderable instances. One example is MovableObject::visitRenderables.

virtual Ogre::Renderable::Visitor::~Visitor ( ) [virtual]

Virtual destructor needed as class has virtual methods.

virtual void Ogre::Renderable::Visitor::visit	(	Renderable *	rend,
		ushort	lodIndex,
		bool	isDebug,
		Any *	pAny = `0`
	)			`[pure virtual]`

Generic visitor method.

Parameters:

	rend	The Renderable instance being visited
	lodIndex	The LOD index to which this Renderable belongs. Some objects support LOD and this will tell you whether the Renderable you're looking at is from the top LOD (0) or otherwise
	isDebug	Whether this is a debug renderable or not.
	pAny	Optional pointer to some additional data that the class calling the visitor may populate if it chooses to.
