	~FPositionVertexBuffer()	Destructor.

Functions

	Name	Description
void	AppendVertices ( const FStaticMeshBuildVertex* ..., const uint32 NumVerticesToAppend )	Appends the specified vertices to the end of the buffer
void	BindPositionVertexBuffer ( const FVertexFactory* VertexFa..., FStaticMeshDataType& Data )
void	CleanUp()	Delete existing resources
void	ClearMetaData()
void	CopyRHIForStreaming ( const FPositionVertexBuffer& Other, bool InAllowCPUAccess )	Copy everything, keeping reference to the same RHI resources.
FVertexBuffe...	CreateRHIBuffer_Async()
FVertexBuffe...	CreateRHIBuffer_RenderThread()	Create an RHI vertex buffer with CPU data.
uint32	GetNumVertices()
FRHIShaderRe...	GetSRV()
uint32	GetStride()	Other accessors.
const void &...	GetVertexData()
void *	GetVertexData()
void	Init ( const TArray< FVector >& InPositio..., bool bInNeedsCPUAccess )
void	Init ( const FPositionVertexBuffer& InVer..., bool bInNeedsCPUAccess )	Initializes this vertex buffer with the contents of the given vertex buffer.
void	Init ( const TArray< FStaticMeshBuildVerte..., bool bInNeedsCPUAccess )	Initializes the buffer with the given vertices, used to convert legacy layouts.
void	Init ( uint32 NumVertices, bool bInNeedsCPUAccess )
void	InitRHIForStreaming ( FRHIVertexBuffer* Intermediate..., TRHIResourceUpdateBatcher< MaxNumUp... )	Similar to Init/ReleaseRHI but only update existing SRV so references to the SRV stays valid
void	ReleaseRHIForStreaming ( TRHIResourceUpdateBatcher< MaxNumUp... )
void	Serialize ( FArchive& Ar, bool bInNeedsCPUAccess )	Serializer
void	SerializeMetaData ( FArchive& Ar )
FVector &	VertexPosition ( uint32 VertexIndex )	Vertex data accessors.
const FVecto...	VertexPosition ( uint32 VertexIndex )

Overridden from FRenderResource

	Name	Description
FString	GetFriendlyName()
void	InitRHI()	Initializes the RHI resources used by this resource.
void	ReleaseRHI()	Releases the RHI resources used by this resource.

Operators

		Name	Description
	void	operator= ( const FPositionVertexBuffer& Other )	Specialized assignment operator, only used when importing LOD's.
