Member Function Documentation

tU64 GetHash	(	tFVF	aFVF,
		tU32	anChunk
	)		const

Hash for FVF|Chunk set.

tVBHMap::iterator GetVB	(	tFVF	anFVF,
		tU32	anChunk
	)

Get the vertex buffer of the specified FVF|Chunk pair.

tU32 GetNextChunk	(	tFVF	aFVF,
		tU32	anNumVerts
	)

Get a new chunk. The number of vertices should be smaller than the number of vertices per VA allowed.

Remarks

anNumVerts is an estimate of the max number of vertices that will go into the chunk. PushVertex will do the actual vertex adding.

tU32 PushVertex	(	tFVF	anFVF,
		tU32	anChunk,
		tU32	anIndex,
		tFVF	aSrcFVF,
		tPtr	apVert
	)

Add a vertex to the specified FVF|Chunk|Index.

Remarks

Will convert the FVF from srcFVF to the FVF of the chunk.

Returns

The index of the pushed vertex.

tU32 GetVertexIndex	(	tFVF	anFVF,
		tU32	anChunk,
		tU32	anIndex
	)		const

Get the index of the specified vertex in the final VA.

const tU8* GetVerts	(	tFVF	anFVF,
		tU32	anChunk
	)		const

Get all vertices of the specified FVF|Chunk.

tU32 GetNumVerts	(	tFVF	anFVF,
		tU32	anChunk
	)		const

Get the number of vertices of the specified FVF|Chunk.

iVertexArray* GetVA	(	iGraphics *	apGraphics,
		tFVF	anFVF,
		tU32	anChunk,
		eArrayUsage	aUsage
	)

Get the vertex array of the specified FVF|Chunk.

iVertexArray* GetVA	(	iGraphics *	apGraphics,
		tVBHMap::iterator	itVB,
		eArrayUsage	aUsage
	)

tVBHMap::iterator GetVBBeginIt

(

)

Get the first VB iterator.

tVBHMap::iterator GetVBEndIt

(

)

Get the end VB iterator.

tU32 GetTotalNumVerts

(

)

const

Get the total number of vertices.

Remarks

This is initialized by GetVA

tU64 GetTotalMemory

(

)

const

Get the total memory in bytes.

Remarks

This is initialized by GetVA
