DirectX11 2窗口渲染

Question

如何将我的对象用DirectX渲染到2个分离的Windows？

Answer 1

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

1如果您通过createViceanDswapchain创建了设备，则需要获得IDXGifactory first

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其他Swapchain

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

然后创建渲染目标视图

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;

最后只是设置渲染目标并绘制一些东西！

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

我希望这很有帮助。

最佳问候：）
