Direct3D：從紋理創建渲染目標視圖

我想從紋理創建渲染目標視圖，以用於多個目標渲染。我目前能夠爲後臺緩衝區創建渲染目標視圖 - 所有這些都很好地工作。此外，我可以創建紋理。但是，當我嘗試從它構建視圖時，出現錯誤。Direct3D：從紋理創建渲染目標視圖

首先，這裏的代碼：

D3D11_TEXTURE2D_DESC textureDesc; 
ZeroMemory(&textureDesc, sizeof(textureDesc)); 

textureDesc.ArraySize = 1; 
textureDesc.BindFlags = D3D11_BIND_RENDER_TARGET | D3D11_BIND_SHADER_RESOURCE; 
textureDesc.CPUAccessFlags = 0; 
textureDesc.Format = DXGI_FORMAT_R32_FLOAT; 
textureDesc.Height = m_renderTargetSize.Height; 
textureDesc.Width = m_renderTargetSize.Width; 
textureDesc.MipLevels = 1; 
textureDesc.MiscFlags = 0; 
textureDesc.SampleDesc.Count = 1; 
textureDesc.SampleDesc.Quality = 0; 
textureDesc.Usage = D3D11_USAGE_DEFAULT; 

ComPtr<ID3D11Texture2D> texture; 
DX::ThrowIfFailed(
    m_d3dDevice->CreateTexture2D(
     &textureDesc, 
     nullptr, 
     &texture 
     ) 
    ); 

D3D11_RENDER_TARGET_VIEW_DESC renderTargetViewDescription; 
ZeroMemory(&renderTargetViewDescription, sizeof(renderTargetViewDescription)); 
renderTargetViewDescription.Format = textureDesc.Format; 

DX::ThrowIfFailed(
    m_d3dDevice->CreateRenderTargetView(
     texture, 
     &renderTargetViewDescription, 
     &m_renderTargetView[1] 
     ) 
    );

我正在從與調用行的編譯器下面的錯誤CreateRenderTargetView：

Error: no suitable conversion function from "Microsoft::WRL::ComPtr" to "ID3D11Resource *" exists.

According to MSDN，ID3D11Texture2D從ID3D11Resource繼承。我必須先以某種方式上傳嗎？

我正在使用DirectX 11，並使用vc110進行編譯。

看來，WRL的ComPtr不支持隱式轉換到T *（不像ATL的但是CComPtr），所以你需要使用GET方法：

DX::ThrowIfFailed(
    m_d3dDevice->CreateRenderTargetView(
     texture.Get(), 
     &renderTargetViewDescription, 
     &m_renderTargetView[1] 
     ) 
    );
