Store vertex and index data.

Constructor & Destructor Documentation

BufferImpl()

BufferImpl	(	size_t	size,
		BufferType	type,
		BufferUsage	usage,
		const void *	initial,
		uint32_t	stride = 0 )

Parameters

size	Specifies the size in bytes of the buffer object's new data store.
type	Specifies the target buffer object. The symbolic constant must be BufferType::VERTEX or BufferType::INDEX.
usage	Specifies the expected usage pattern of the data store. The symbolic constant must be BufferUsage::STATIC, BufferUsage::DYNAMIC.

Member Function Documentation

updateData()

void updateData ( const void * data, size_t size )

overridevirtual

Update buffer data.

Parameters

data	Specifies a pointer to data that will be copied into the data store for initialization.
size	Specifies the size in bytes of the data store region being replaced.

See also

updateSubData(void* data, unsigned int offset, unsigned int size)

Implements Buffer.

updateSubData()

void updateSubData ( const void * data, size_t offset, size_t size )

overridevirtual

Update buffer sub-region data.

Parameters

data	Specifies a pointer to the new data that will be copied into the data store.
offset	Specifies the offset into the buffer object's data store where data replacement will begin, measured in bytes.
size	Specifies the size in bytes of the data store region being replaced.

See also

updateData(void* data, unsigned int size)

Implements Buffer.

usingDefaultStoredData()

void usingDefaultStoredData ( bool needDefaultStoredData )

overridevirtual

Static buffer data will automatically stored when it comes to foreground.

This interface is used to indicate whether external data needs to be used to update the buffer(false) instead of using the default stored data(true).

Parameters

needDefaultStoredData

Specifies whether to use the default stored data.

Implements Buffer.

internalHandle()

GLuint internalHandle ( ) const

inline

Get buffer object.

Returns

Buffer object.
