Detailed Description

Summary class collecting together index data source information.

Constructor & Destructor Documentation

IndexData()

Ogre::IndexData::IndexData

(

)

~IndexData()

Ogre::IndexData::~IndexData

(

)

Member Function Documentation

clone()

IndexData* Ogre::IndexData::clone	(	bool	copyData = true,
		HardwareBufferManagerBase *	mgr = 0
	)		const

Clones this index data, potentially including replicating the index buffer.

Parameters

copyData	Whether to create new buffers too or just reference the existing ones
mgr	If supplied, the buffer manager through which copies should be made

Remarks

The caller is expected to delete the returned pointer when finished

optimiseVertexCacheTriList()

void Ogre::IndexData::optimiseVertexCacheTriList

(

void

)

Re-order the indexes in this index data structure to be more vertex cache friendly; that is to re-use the same vertices as close together as possible.

Remarks

Can only be used for index data which consists of triangle lists. It would in fact be pointless to use it on triangle strips or fans in any case.
