如何从 IDXGIFactory4 或 ID3D12Device

问题描述

如何从 IdxgiFactory4 或 ID3D12Device 中检索 dxgiDevice

    CreatedxgiFactory2(dxgi_CREATE_FACTORY_DEBUG,IID_PPV_ARGS(&m_dxgiFactory));
    GetHardwareAdapter(m_dxgiFactory.Get(),&hardwareAdapter);
    D3D12CreateDevice(hardwareAdapter.Get(),D3D_FEATURE_LEVEL_11_0,IID_PPV_ARGS(&m_device));

    // some initial code

    // Create the Direct2D device that links back to the Direct3D device
    ComPtr<ID2D1Device1> d2Device;
    d2Factory->CreateDevice(dxgiDevice.Get(),d2Device.GetAddressOf());

    // some initial code

    ComPtr<IDCompositionDevice> dcompDevice;
    DCompositionCreateDevice(dxgiDevice.Get(),__uuidof(dcompDevice),reinterpret_cast<void **>(dcompDevice.GetAddressOf()));
