无法创建 DX11 渲染目标视图

Question

我正在尝试开始使用 DirectX 11 游戏编程，但由于某种原因，我根本无法使用 ID3D11Device::CreateRenderTargetView() 创建渲染目标视图。

（顺便说一句，我使用 VS for Desktop 2013，我的 GPU 支持的最高功能级别是 11_0。我运行的是 Windows 8.1。）

这是我认为相关的代码：

D3D11_TEXTURE2D_DESC backBufferDesc;
    ZeroMemory(&backBufferDesc, sizeof(backBufferDesc));
    backBufferDesc.ArraySize = 1;
    backBufferDesc.BindFlags = D3D11_BIND_RENDER_TARGET | D3D11_BIND_SHADER_RESOURCE;
    backBufferDesc.CPUAccessFlags = 0;
    backBufferDesc.Format = DXGI_FORMAT_R32_FLOAT;
    backBufferDesc.Height = nHeight;
    backBufferDesc.Width = nWidth;
    backBufferDesc.MipLevels = 1;
    backBufferDesc.MiscFlags = 0;
    backBufferDesc.SampleDesc.Count = 1;
    backBufferDesc.SampleDesc.Quality = 0;
    backBufferDesc.Usage = D3D11_USAGE_DEFAULT;

    ID3D11Texture2D* backBufferTexture;
    result = d3dDevice_ -> CreateTexture2D(&backBufferDesc, 0, &backBufferTexture);
    if (FAILED(result))
    {
        MessageBox(0, "Failed to create the back buffer texture!", "DirectX Error", MB_OK);
        return false;
    }

    result = swapChain_->GetBuffer(0, __uuidof(ID3D11Texture2D), (LPVOID*)&backBufferTexture);
    if (FAILED(result))
    {
        MessageBox(0, "Failed to get the swap chain back buffer!", "DirectX Error", MB_OK);
        return false;
    }

    D3D11_RENDER_TARGET_VIEW_DESC rtvDesc;
    ZeroMemory(&rtvDesc, sizeof(rtvDesc));
    rtvDesc.Format = backBufferDesc.Format;

    result = d3dDevice_->CreateRenderTargetView(backBufferTexture, &rtvDesc, &backBufferTarget_);
    if (backBufferTexture)
        backBufferTexture->Release();
    if (FAILED(result))
    {
        MessageBox(0, "Failed to create the render target view!", "DirectX Error", MB_OK);
        return false;
    }

使用调试设备会给您一个人类可读的错误。

根据我对代码的阅读，您尚未填写 rtvDesc 的 ViewDimension 字段。
