Detailed Description

VertexData is a class used for specify input streams for GPU rendering pipeline, a VertexData will be composed by several streams, every stream will contain a VertexStreamAttribute and the binding VertexBuffer.

Streams will be identified by semantic. NA

Member Function Documentation

setStream()

bool setStream	(	VertexBuffer *	buffer,
		const VertexStreamAttribute &	stream
	)

Set a stream to VertexData,given that stream is identified by semantic, so if the semantic is not specified before, it will add a stream, or it will override the old one.

Parameters

buffer	The binding buffer of the stream.
stream	The binding vertex attribute, its member semantic will be used as the identifier.

removeStream()

void removeStream

(

int

semantic

)

Remove the given streams.

Parameters

semantic

The semantic of the stream.

getStreamAttribute() [1/2]

const VertexStreamAttribute* getStreamAttribute

(

int

semantic

)

const

Get the attribute of stream, const version.

Parameters

semantic

The semantic of the stream.

getStreamAttribute() [2/2]

VertexStreamAttribute* getStreamAttribute

(

int

semantic

)

Get the attribute of stream.

Parameters

semantic

The semantic of the stream.

getStreamBuffer()

VertexBuffer* getStreamBuffer

(

int

semantic

)

const

Get the binded buffer of the stream.

Parameters

semantic

The semantic of the stream.
