inline

size_t makVrv::DtGlTextureBufferObject::sizeInBytes

(

void

)

const

Size in bytes of the texture buffer object.

void makVrv::DtGlTextureBufferObject::copyData	(	void *	pData,
		size_t	sizeInBytes,
		size_t	offsetInBytes = 0
	)

Upload data to the buffer. offset + size <= size of buffer.

void makVrv::DtGlTextureBufferObject::copyAndOrphanStreamedData	(	void *	pData,
		size_t	sizeInBytes
	)

Upload and resize buffer, assumes used for just a frame.

void makVrv::DtGlTextureBufferObject::copyDataMapped	(	void *	pData,
		size_t	sizeInBytes,
		size_t	offsetInBytes = 0
	)

Upload data to the buffer using glMapBuffer.
