IDirect3DRMShadow

Applications use the IDirect3DRMShadow interface to initialize Direct3DRMShadow objects. Note that this initialization is not necessary if the application uses the IDirect3DRM::CreateShadow method; it is required only if the application uses the IDirect3DRM::CreateObject method to create the shadow.

This section is a reference to the methods of the IDirect3DRMShadow interface. For a conceptual overview, see IDirect3DRMShadow Interface.

The IDirect3DRMShadow interface supports the Init method.

The IDirect3DRMShadow interface, like all Component Object Model (COM) interfaces, inherits the IUnknown interface methods. The IUnknown interface supports the following three methods:

AddRef

QueryInterface

Release

In addition, the IDirect3DRMShadow interface inherits the following methods from the IDirect3DRMObject interface:

AddDestroyCallback

Clone

DeleteDestroyCallback

GetAppData

GetClassName

GetName

SetAppData

SetName

The Direct3DRMShadow object is obtained by using the IDirect3DRM::CreateShadow method.
