Rendering to multi window in DX10

* 윈도우별로 SwapChain을 생성하여 사용하면 된다. DX10에서는 SwapChain에 윈도우를 직접 지정할 수 있다.

 

 

* 처리 순서

   1. 윈도우별로 SwapChain과 RenderTargetView를 생성

   2. RenderTarget 설정

   3. 렌더링

   4. IDXGISwapChain::Present() 호출

   5. 윈도우별로 2~4 수행

 

 

* 코드 예

 

   1. SwapChain, RenderTargetView 생성

RECT rc;  GetClientRect( hWnd, &rc );  UINT nScreenWidth = rc.right - rc.left;  UINT nScreenHeight = rc.bottom - rc.top;  DXGI_SWAP_CHAIN_DESC sd;  ZeroMemory( &sd, sizeof( sd ) );  sd.BufferCount = 1;  sd.BufferDesc.Width = nScreenWidth;  sd.BufferDesc.Height = nScreenHeight;  sd.BufferDesc.Format = DXGI_FORMAT_R8G8B8A8_UNORM;  sd.BufferDesc.RefreshRate.Numerator = 60;  sd.BufferDesc.RefreshRate.Denominator = 1;  sd.BufferUsage = DXGI_USAGE_RENDER_TARGET_OUTPUT;  sd.OutputWindow = hWnd;  sd.SampleDesc.Count = 1;  sd.SampleDesc.Quality = 0;  sd.Windowed = TRUE;   IDXGISwapChain* pSwapChain;  pDXGIFactory->CreateSwapChain(pd3dDevice, &sd, &pSwapChain);       ID3D10Resource * pBB;  pSwapChain->GetBuffer( 0, __uuidof( ID3D10Texture2D ), ( LPVOID* )&pBB);  ID3D10RenderTargetView * pView;  D3D10_RENDER_TARGET_VIEW_DESC rtd;  rtd.Format = DXGI_FORMAT_R8G8B8A8_UNORM;  rtd.ViewDimension = D3D10_RTV_DIMENSION_TEXTURE2D;  rtd.Texture2D.MipSlice = 0;   pD3D10Device->CreateRenderTargetView(pBB, &rtd, &pView),

 

 

   2. RenderTarget 설정 

pD3D10Device->OMSetRenderTargets(1, &pView, 0);

 

 

   3. IDXGISwapChain::Present() 호출 

pSwapChain->Present( 0, 0 );
