c++ - DirectX11 2 窗口渲染

Question

如何使用 DirectX 将我的对象渲染到 2 个独立的窗口中？

Answer 1

您需要为每个窗口创建一个 SwapChain 和 RenderTargetView。

1 如果你通过CreateDeviceAndSwapChain创建你的设备你需要先获取IDXGIFactory

IDXGIDevice * device;
d3ddevice->QueryInterface(__uuidof(IDXGIDevice), (void**)&device);

IDXGIAdapter * adapter;
device->GetParent(__uuidof(IDXGIAdapter), (void**)&adapter);

IDXGIFactory * factory;
adapter->GetParent(__uuidof(DDXGIFactory), (void**)&factory);

使用 DXGIFactory，您可以为新窗口创建额外的交换链

factory->CreateSwapChain(g_pd3dDevice, &sd, &g_pSwapChain2);

然后创建渲染目标 View

ID3D11Texture2D* pBackBuffer = NULL;
hr = g_pSwapChain2->GetBuffer( 0, __uuidof( ID3D11Texture2D ), ( LPVOID* )&pBackBuffer );
if( FAILED( hr ) )
    return hr;

hr = g_pd3dDevice->CreateRenderTargetView( pBackBuffer, NULL, &g_pRenderTargetView );
pBackBuffer->Release();
if( FAILED( hr ) )
    return hr;

最后只需设置您的渲染目标并绘制一些东西!

g_immediateContext->OMSetRenderTargets(1, &g_RenderTargetView, NULL);
....

我希望这对您有所帮助。
