Applications use the methods of the IDirect3DVertexBuffer interface to manipulate a collection of vertices for use with the IDirect3DDevice3::DrawPrimitiveVB and IDirect3DDevice3::DrawIndexedPrimitiveVB rendering methods. This section is a reference to the methods of this interface. For a conceptual overview, see Vertex Buffers.
This methods of the IDirect3DVertexBuffer interface can be organized into the following groups:
| Information | GetVertexBufferDesc |
| Vertex data | Lock |
| Optimize | |
| ProcessVertices | |
| Unlock |
The IDirect3DVertexBuffer interface, like all COM interfaces, inherits the IUnknown interface methods. The IUnknown interface supports the following three methods:
| IUnknown | AddRef |
| QueryInterface | |
| Release |
The LPDIRECT3DVERTEXBUFFER data type is defined as a pointer to the IDirect3DVertexBuffer interface:
typedef struct IDirect3DVertexBuffer *LPDIRECT3DVERTEXBUFFER
