◆ AllocateChunk()

CVertexBufferManager::Handle CVertexBufferManager::AllocateChunk	(	const size_t	vertexSize,
		const size_t	numberOfVertices,
		const Renderer::Backend::IBuffer::Type	type,
		const uint32_t	usage,
		void *	backingStore = `nullptr`,
		Group	group = `Group::DEFAULT`
	)

Try to allocate a vertex buffer of the given size and type.

AllocateChunk: try to allocate a buffer of given number of vertices (each of given size), with the given type, and using the given texture - return null if no free chunks available.

Parameters

vertexSize	size of each vertex in the buffer
numberOfVertices	number of vertices in the buffer
type	buffer type
dynamic	will be buffer updated frequently or not
backingStore	if not dynamic, this is nullptr; else for dynamic, this must be a copy of the vertex data that remains valid for the lifetime of the VBChunk

Returns: chunk, or empty handle if no free chunks available

◆ GetBytesAllocated()

size_t CVertexBufferManager::GetBytesAllocated ( ) const

◆ GetBytesReserved()

size_t CVertexBufferManager::GetBytesReserved ( ) const

◆ Release()

void CVertexBufferManager::Release ( CVertexBuffer::VBChunk * chunk )

Returns the given chunk to its owning buffer.
