DirectX 11 每个网格都以 0 的形式绘制到深度缓冲区，导致实际上没有深度测试

Question

据我所知，我已经正确设置了深度测试，但是对象只是从头到尾绘制的。我查看了图形调试器，似乎在绘制网格时，无论其距离如何，它都会将深度缓冲区设置为 0。

    D3D11_TEXTURE2D_DESC depthBufferDesc;
    d3d11FrameBuffer->GetDesc(&depthBufferDesc);

    d3d11FrameBuffer->Release();

    depthBufferDesc.Format = DXGI_FORMAT_D24_UNORM_S8_UINT;
    depthBufferDesc.BindFlags = D3D11_BIND_DEPTH_STENCIL;
    depthBufferDesc.Width = 1920;
    depthBufferDesc.Height = 1080;
    depthBufferDesc.MipLevels = 1;
    depthBufferDesc.ArraySize = 1;
    depthBufferDesc.SampleDesc.Count = 1;
    depthBufferDesc.SampleDesc.Quality = 0;
    depthBufferDesc.Usage = D3D11_USAGE_DEFAULT;
    depthBufferDesc.CPUAccessFlags = 0;
    depthBufferDesc.MiscFlags = 0;


    ID3D11Texture2D* depthBuffer;
    HRESULT res = d3d11Device->CreateTexture2D(&depthBufferDesc, nullptr, &depthBuffer);
    
    D3D11_DEPTH_STENCIL_VIEW_DESC depthStencilViewDesc;
    ZeroMemory(&depthStencilViewDesc, sizeof(depthStencilViewDesc));
    depthStencilViewDesc.Format = DXGI_FORMAT_D24_UNORM_S8_UINT;
    depthStencilViewDesc.ViewDimension = D3D11_DSV_DIMENSION_TEXTURE2D;
    depthStencilViewDesc.Texture2D.MipSlice = 0;

    res = d3d11Device->CreateDepthStencilView(depthBuffer, nullptr, depthBufferView);

    ID3D11DepthStencilState* depthStencilState;
    {
        D3D11_DEPTH_STENCIL_DESC depthStencilDesc = {};
        depthStencilDesc.DepthEnable = true;
        depthStencilDesc.DepthWriteMask = D3D11_DEPTH_WRITE_MASK_ALL;
        depthStencilDesc.DepthFunc = D3D11_COMPARISON_LESS;
        depthStencilDesc.StencilEnable = false;
        depthStencilDesc.StencilReadMask = 0xFF;
        depthStencilDesc.StencilWriteMask = 0xFF;
        depthStencilDesc.FrontFace.StencilFailOp = D3D11_STENCIL_OP_KEEP;
        depthStencilDesc.FrontFace.StencilDepthFailOp = D3D11_STENCIL_OP_INCR;
        depthStencilDesc.FrontFace.StencilPassOp = D3D11_STENCIL_OP_KEEP;
        depthStencilDesc.FrontFace.StencilFunc = D3D11_COMPARISON_ALWAYS;
        depthStencilDesc.BackFace.StencilFailOp = D3D11_STENCIL_OP_KEEP;
        depthStencilDesc.BackFace.StencilDepthFailOp = D3D11_STENCIL_OP_DECR;
        depthStencilDesc.BackFace.StencilPassOp = D3D11_STENCIL_OP_KEEP;
        depthStencilDesc.BackFace.StencilFunc = D3D11_COMPARISON_ALWAYS;
        


        d3d11Device->CreateDepthStencilState(&depthStencilDesc, &depthStencilState);
    }

        d3d11DeviceContext->RSSetState(rasterizerState);
        d3d11DeviceContext->OMSetDepthStencilState(depthStencilState, 1);

        d3d11DeviceContext->OMSetRenderTargets(1, &d3d11FrameBufferView, depthBufferView);

我尝试更改各种参数并移动某些代码的位置，但这没有用。我找不到任何其他似乎适用于此的问题。 我在光栅器上禁用了深度剪辑，因为当我启用它时，不会渲染任何内容，但据我所知，它不应该对此产生任何影响。

Answer 1

你为什么有：

depthStencilDesc.StencilEnable = false;

必须将其设置为

true

。
