跟以前的一样，对于模板缓冲区，也是声明定义一系列的结构体，并在渲染的时候 打开/关闭 他们
在使用CreateRenderTargetView创建视图之后，声明定义深度模板缓冲区：
ID3D11Texture2D *depthStencilBuffer(NULL); //测试多重采样抗锯齿等级 UINT x4MsaaQuality; dev->CheckMultisampleQualityLevels(DXGI_FORMAT_R8G8B8A8_UNORM, 4, &x4MsaaQuality); printf("CheckMultisampleQualityLevels:%d\n", x4MsaaQuality); // D3D11_TEXTURE2D_DESC dsDesc; dsDesc.Format = DXGI_FORMAT_D24_UNORM_S8_UINT; dsDesc.Width = 1200; dsDesc.Height = 600; dsDesc.BindFlags = D3D11_BIND_DEPTH_STENCIL; dsDesc.MipLevels = 1; dsDesc.ArraySize = 1; dsDesc.CPUAccessFlags = 0; dsDesc.SampleDesc.Count = (x4MsaaQuality<1?1:4); dsDesc.SampleDesc.Quality = (x4MsaaQuality<1 ? 0 : x4MsaaQuality - 1); dsDesc.MiscFlags = 0; dsDesc.Usage = D3D11_USAGE_DEFAULT; hr = dev->CreateTexture2D(&dsDesc, 0, &depthStencilBuffer); if (FAILED(hr)) { return false; } hr = dev->CreateDepthStencilView(depthStencilBuffer, 0, &depthStencilView); if (FAILED(hr)) { return false; } devContext->OMSetRenderTargets(1, &backBuffer, depthStencilView); depthStencilBuffer->Release();
结构：CheckMultisampleQualityLevels验证多重采样抗锯齿的等级------CreateTexture2D创建2D贴图缓冲区------CreateDepthStencilView创建缓冲区视图------OMSetRenderTargets进行绑定。
主要记录一下
D3D11_TEXTURE2D_DESC这个结构：
typedef struct D3D11_TEXTURE2D_DESC { UINT Width; UINT Height; UINT MipLevels; UINT ArraySize; DXGI_FORMAT Format; DXGI_SAMPLE_DESC SampleDesc; D3D11_USAGE Usage; UINT BindFlags; UINT CPUAccessFlags; UINT MiscFlags; } D3D11_TEXTURE2D_DESC;
需要注意的元素：
Width与Height：贴图的高与宽，要与上面创建的视图缓冲区与下面的视窗大小相匹配。
BindFlags：这里我使用DXGI_FORMAT_D24_UNORM_S8_UINT，24位用于深度缓冲区，8位用于模板缓冲区。
SampleDesc：这是一个结构体
typedef struct DXGI_SAMPLE_DESC {
UINT Count;
UINT Quality;
} DXGI_SAMPLE_DESC;
MSDN有这样的解释：
The image quality level. The higher the quality, the lower the performance.
The valid range is between zero and one less than the level returned by ID3D10Device::CheckMultisampleQualityLevels for Direct3D 10
or ID3D11Device::CheckMultisampleQualityLevels for Direct3D 11.
也可以见书中4.1.7关于多重采样的内容。
注意，这里的多重采样的元素设置错误，可能会导致无法绘制的BUG。
然后是设定模板测试：
代码
HRESULT DrawFunction::CreateStencilDesc(void) { HRESULT hr = S_OK;//ret D3D11_DEPTH_STENCIL_DESC stencilDesc; ZeroMemory(&stencilDesc, sizeof(stencilDesc)); stencilDesc.DepthEnable = FALSE; stencilDesc.DepthWriteMask = D3D11_DEPTH_WRITE_MASK_ZERO; stencilDesc.DepthFunc = D3D11_COMPARISON_ALWAYS; stencilDesc.StencilEnable = TRUE; stencilDesc.StencilReadMask = 0xff; stencilDesc.StencilWriteMask = 0xff; stencilDesc.FrontFace.StencilFailOp = D3D11_STENCIL_OP_KEEP; stencilDesc.FrontFace.StencilDepthFailOp = D3D11_STENCIL_OP_KEEP; stencilDesc.FrontFace.StencilPassOp = D3D11_STENCIL_OP_REPLACE; stencilDesc.FrontFace.StencilFunc = D3D11_COMPARISON_ALWAYS; stencilDesc.BackFace = stencilDesc.FrontFace; hr = dev->CreateDepthStencilState(&stencilDesc, &pStencilReplace); stencilDesc.FrontFace.StencilPassOp = D3D11_STENCIL_OP_KEEP; stencilDesc.FrontFace.StencilFunc = D3D11_COMPARISON_EQUAL; stencilDesc.BackFace = stencilDesc.FrontFace; hr = dev->CreateDepthStencilState(&stencilDesc, &pStencilTest); return hr; }
结构体：
typedef struct D3D11_DEPTH_STENCIL_DESC { BOOL DepthEnable; D3D11_DEPTH_WRITE_MASK DepthWriteMask; D3D11_COMPARISON_FUNC DepthFunc; BOOL StencilEnable; UINT8 StencilReadMask; UINT8 StencilWriteMask; D3D11_DEPTH_STENCILOP_DESC FrontFace; D3D11_DEPTH_STENCILOP_DESC BackFace; } D3D11_DEPTH_STENCIL_DESC;
需要注意的元素：
掩码元素StencilReadMask与StencilWriteMask，就是指当读取/写入模板元素时，用数据与掩码进行AND与运算。代码中我设置为0xFF表示不做任何变化。
//模板未更新完，先放一个简单的demon，在之后学习的实例的时候再进行补充。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。
