The HardwareBufferManager class is the factory hub of all the objects in the new geometry system. You create and destroy the majority of the objects you use to define geometry through this class. It’s a Singleton, so you access it by doing HardwareBufferManager::getSingleton() - however be aware that it is only guaranteed to exist after the RenderSystem has been initialised (after you call Root::initialise); this is because the objects created are invariably API-specific, although you will deal with them through one common interface.
VertexDeclaration* decl = HardwareBufferManager::getSingleton().createVertexDeclaration();
HardwareVertexBufferSharedPtr vbuf = HardwareBufferManager::getSingleton().createVertexBuffer( 3*sizeof(Real), // size of one whole vertex numVertices, // number of vertices HardwareBuffer::HBU_STATIC_WRITE_ONLY, // usage false); // no shadow buffer
Don’t worry about the details of the above, we’ll cover that in the later sections. The important thing to remember is to always create objects through the HardwareBufferManager, don’t use ’new’ (it won’t work anyway in most cases).
