Contoh

// Create a new Windows Console Application (C++/WinRT) project, and
// replace the contents of `pch.h` and `main.cpp` source code files with the code below.
// Be aware that the code below omits the details of obtaining a WinRT Direct3DDevice in
// the first segment of code, and obtaining a native DirectX device in the second segment.
// The code shows only how to perform the conversion between the two.

Keterangan

Jika Anda menggunakan C++/WinRT, maka untuk bergerak bolak-balik antara IDirect3DDevice dan IDXGIDevice, gunakan fungsi IDirect3DDxgiInterfaceAccess::GetInterface dan CreateDirect3D11DeviceFromDXGIDevice . Anda dapat melihat contoh kode lain dalam Interoperatasi asli Komposisi dengan DirectX dan Direct2D.

Jika Anda menggunakan C++/CX, maka untuk bergerak bolak-balik antara IDirect3DDevice dan IDXGIDevice, gunakan fungsi CreateDirect3DDevice dan GetDXGIInterface(IDirect3DDevice^, DXGI_TYPE**).

Metode

Dispose()	Melakukan tugas yang ditentukan aplikasi yang terkait dengan membebaskan, melepaskan, atau mereset sumber daya yang tidak terkelola.
Trim()	Memangkas memori grafis apa pun yang dialokasikan oleh perangkat grafis atas nama aplikasi.
