Detailed Description

Cache of 3D models (avoids re-loading the same 3D model files).

Since a 3D model may be cached, its osg::Node may be shared by multiple parents. The reason a 3D model can exist in multiple locations is because its shared node is placed under separate transform nodes.

)

Flush the cache of 3D models. Cache should be flushed before reloading the scene when any 3D models were modified externally.

shptr< Graph > graph::ModelCache::LoadModel	(	const string &	modelFilename,
		const fp	scale = 1.0f,
		const bool	loadCopy = false
	)

Directly load a cached 3D model else THROW EXCEPTION.
