Applications use the methods of the IDirect3DLight interface to retrieve and set the capabilities of lights. This section is a reference to the methods of this interface. For a conceptual overview, see Lights.
The IDirect3DLight interface is obtained by calling the IDirect3D3::CreateLight method.
The methods of the IDirect3DLight interface can be organized into the following groups:
| Get and set | GetLight |
| SetLight | |
| Initialization | Initialize |
The IDirect3DLight interface, like all COM interfaces, inherits the IUnknown interface methods. The IUnknown interface supports the following three methods:
| IUnknown | AddRef |
| QueryInterface | |
| Release |
The LPDIRECT3DLIGHT type is defined as a pointer to the IDirect3DLight interface:
typedef struct IDirect3DLight *LPDIRECT3DLIGHT;
