IDirect3DRMDevice and IDirect3DRMDeviceArray Interfaces
All forms of rendered output must be associated with an output device. The device object represents the visual display destination for the renderer.
The renderer's behavior depends on the type of output device that is specified. You can define multiple viewports on a device, allowing different aspects of the scene to be viewed simultaneously. You can also specify any number of devices, allowing multiple destination devices for the same scene.
Retained Mode supports devices that render directly to the screen, to windows, or into application memory.
