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
copyDataWhether to create new buffers too or just reference the existing ones
mgrIf 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.
