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

  1如果您通过CreateDeviceAndSwapChain创建了设备，则需要先获取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);
  ....
  

  希望这有用 .

  最好的问候Quest :)
