Constructor & Destructor Documentation

BufferGL()

inviwo::BufferGL::BufferGL	(	size_t	size,
		const DataFormatBase *	format,
		BufferUsage	usage,
		BufferTarget	target,
		std::shared_ptr< BufferObject >	data = std::shared_ptr< BufferObject >(nullptr) )

Create a buffer stored on the GPU.

Parameters

size	Size in bytes.
format	Data format
usage	BufferUsage::Static if not changing all the time, else BufferUsage::Dynamic.
target	BufferTarget::Data for vertex buffers and BufferTarget::Index for index buffers
data	Will be created if nullptr.
