Parameter
[in] pDevice
Jenis: IUnknown*
Menentukan perangkat Direct3D 12 yang sudah ada sebelumnya untuk digunakan untuk interop Direct3D 11. Mungkin bukan NULL.
Flags
Jenis: UINT
Satu atau beberapa bendera OR bitwise dari D3D11_CREATE_DEVICE_FLAG. Ini adalah bendera yang sama seperti yang digunakan oleh D3D11CreateDeviceAndSwapChain. Menentukan lapisan runtime mana yang akan diaktifkan. Bendera harus kompatibel dengan bendera perangkat, dan NodeMask-nya harus merupakan subset dari NodeMask yang disediakan untuk API saat ini.
[in, optional] pFeatureLevels
Jenis: const D3D_FEATURE_LEVEL*
Array dari salah satu hal berikut ini:
- D3D_FEATURE_LEVEL_12_1
- D3D_FEATURE_LEVEL_12_0
- D3D_FEATURE_LEVEL_11_1
- D3D_FEATURE_LEVEL_11_0
- D3D_FEATURE_LEVEL_10_1
- D3D_FEATURE_LEVEL_10_0
- D3D_FEATURE_LEVEL_9_3
- D3D_FEATURE_LEVEL_9_2
- D3D_FEATURE_LEVEL_9_1
Tingkat fitur pertama yang kurang dari atau sama dengan tingkat fitur perangkat Direct3D 12 akan digunakan untuk melakukan validasi Direct3D 11. Pembuatan akan gagal jika tidak ada tingkat fitur yang dapat diterima yang disediakan. Menyediakan NULL akan default ke tingkat fitur perangkat Direct3D 12.
FeatureLevels
Jenis: UINT
Ukuran (yaitu, jumlah elemen dalam) array pFeatureLevels .
[in, optional] ppCommandQueues
Jenis: IUnknown* const *
Array antrean unik untuk digunakan D3D11On12. Antrean harus dari jenis antrean perintah 3D.
NumQueues
Jenis: UINT
Ukuran (yaitu, jumlah elemen dalam) array ppCommandQueues .
NodeMask
Jenis: UINT
Simpul mana dari perangkat Direct3D 12 yang akan digunakan. Hanya 1 bit yang dapat diatur.
[out, optional] ppDevice
Jenis: ID3D11Device**
Penunjuk ke ID3D11Device yang dikembalikan. Mungkin NULL.
[out, optional] ppImmediateContext
Jenis: ID3D11DeviceContext**
Penunjuk ke ID3D11DeviceContext yang dikembalikan. Mungkin NULL.
[out, optional] pChosenFeatureLevel
Jenis: D3D_FEATURE_LEVEL*
Penunjuk ke tingkat fitur yang dikembalikan. Mungkin NULL.
Nilai kembali
Jenis: HRESULT
Metode ini mengembalikan salah satu Kode Pengembalian Direct3D 12 yang didokumentasikan untuk D3D11CreateDevice.
Metode ini mengembalikan DXGI_ERROR_SDK_COMPONENT_MISSING jika Anda menentukan D3D11_CREATE_DEVICE_DEBUG di Bendera dan versi lapisan debug yang salah diinstal pada komputer Anda. Instal Windows SDK terbaru untuk mendapatkan versi yang benar.
Keterangan
Tanda tangan fungsi PFN_D3D11ON12_CREATE_DEVICE disediakan sebagai typedef, sehingga Anda dapat menggunakan teknik penautan dinamis (GetProcAddress) alih-alih menautkan secara statis.
