Applications use the methods of the IDirect3DRMLight interface to interact with light objects. This section is a reference to the methods of this interface. For a conceptual overview, see IDirect3DRMLight and IDirect3DRMLightArray Interfaces.
The methods of the IDirect3DRMLight interface can be organized into the following groups:
| Attenuation | GetConstantAttenuation |
| GetLinearAttenuation | |
| GetQuadraticAttenuation | |
| SetConstantAttenuation | |
| SetLinearAttenuation | |
| SetQuadraticAttenuation | |
| Color | GetColor |
| SetColor | |
| SetColorRGB | |
| Enable frames | GetEnableFrame |
| SetEnableFrame | |
| Light types | GetType |
| SetType | |
| Range | GetRange |
| SetRange | |
| Spotlight options | GetPenumbra |
| GetUmbra | |
| SetPenumbra | |
| SetUmbra |
The IDirect3DRMLight interface, like all COM interfaces, inherits the IUnknown interface methods. The IUnknown interface supports the following three methods:
AddRef
QueryInterface
Release
In addition, the IDirect3DRMLight interface inherits the following methods from the IDirect3DRMObject interface:
The Direct3DRMLight object is obtained by calling the IDirect3DRM::CreateLight or IDirect3DRM::CreateLightRGB method.
