Applications use the methods of the IDirect3DIndexBuffer9 interface to manipulate an index buffer resource.
IDirect3DResource9| Method | Description |
|---|---|
| IDirect3DIndexBuffer9::GetDesc | Retrieves a description of the index buffer resource. |
| IDirect3DIndexBuffer9::Lock | Locks a range of index data and obtains a pointer to the index buffer memory. |
| IDirect3DIndexBuffer9::Unlock | Unlocks index data. |
The IDirect3DIndexBuffer9 interface is obtained by calling the IDirect3DDevice9::CreateIndexBuffer method.
This interface inherits additional functionality from the IDirect3DResource9 interface.
This interface, like all COM interfaces, inherits from the IUnknown interface.
The LPDIRECT3DINDEXBUFFER9 and PDIRECT3DINDEXBUFFER9 types are defined as pointers to the IDirect3DIndexBuffer9 interface.
