DirectX11 2窗口渲染

Question

如何使用DirectX将对象呈现为两个分隔的窗口？

Answer 1

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

1如果您通过CreateDeviceAndSwapChain创建了您的设备，您需要首先获得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);

然后创建一个呈现目标视图。

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，只需设置渲染目标，并绘制一些东西！

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

我希望这是有帮助的。
