Detailed Description

A class for creating OpenGL Buffer Objects.

Member Function Documentation

void BufferObject::bind ( GLenum _target )

Binds the buffer to a selected buffer target.

Parameters:

[in] _target the target to bind the buffer to

void BufferObject::getParameter	(	GLenum	_value,
		GLint *	_data
	)

Accessor for any OpenGL buffer object parameter.

Parameters:

[in]	_value	the symbolic name of a buffer object parameter
[in]	_data	the data to return the the requested parameter

Loads data into the buffer object.

Parameters:

[in]	_dataSize	the data size in bytes
[in]	_data	the data to load
[in]	_bufferUsage	the expected usage pattern of the data store

void BufferObject::updateSubData	(	GLintptr	_dataOffest,
		GLsizeiptr	_dataSize,
		const GLvoid *	_data
	)

Updates a subset of the buffer object's data.

Parameters:

[in]	_dataOffset	the offset into the buffer object's data
[in]	_dataSize	the pixel data size in bytes
[in]	_data	the pixel data to load
