The device allows the scene and its component parts to be rendered with various degrees of realism. Each mesh can have its own quality, but the maximum quality available for a mesh is that of the device.
An application can change the rendering quality of a device by using the IDirect3DRMDevice::SetQuality and IDirect3DRMMeshBuilder::SetQuality methods. To retrieve the rendering quality for a device, it can use the IDirect3DRMDevice::GetQuality and IDirect3DRMMeshBuilder::GetQuality methods.
