Комментарии

Если вы используете C++/WinRT, то для перемещения между IDirect3DDevice и IDXGIDevice используйте функции IDirect3DxgiInterfaceAccess::GetInterface и CreateDirect3D11DeviceFromDXGIDevice . Вы можете увидеть другой пример кода в статье Собственное взаимодействие композиции с DirectX и Direct2D.

Если вы используете C++/CX, то для перемещения между IDirect3Device и IDXGIDevice используйте функции CreateDirect3Device и GetDXGIInterface(IDirect3DDevice^, DXGI_TYPE** ).
