CD3D11_SAMPLER_DESC 结构 (d3d11.h)

表示采样器状态，并提供用于创建采样器状态的便捷方法。

语法

struct CD3D11_SAMPLER_DESC : D3D11_SAMPLER_DESC {
  void CD3D11_SAMPLER_DESC();
  void CD3D11_SAMPLER_DESC(
    const D3D11_SAMPLER_DESC & o
  );
  void CD3D11_SAMPLER_DESC(
    CD3D11_DEFAULT unnamedParam1
  );
  void CD3D11_SAMPLER_DESC(
    D3D11_FILTER               filter,
    D3D11_TEXTURE_ADDRESS_MODE addressU,
    D3D11_TEXTURE_ADDRESS_MODE addressV,
    D3D11_TEXTURE_ADDRESS_MODE addressW,
    FLOAT                      mipLODBias,
    UINT                       maxAnisotropy,
    D3D11_COMPARISON_FUNC      comparisonFunc,
    const FLOAT                *borderColor,
    FLOAT                      minLOD,
    FLOAT                      maxLOD
  );
  void ~CD3D11_SAMPLER_DESC();
};

注解

下面是 D3D11.h 定义 CD3D11_SAMPLER_DESC的方式：

struct CD3D11_SAMPLER_DESC : public D3D11_SAMPLER_DESC
{
    CD3D11_SAMPLER_DESC()
    {}
    explicit CD3D11_SAMPLER_DESC( const D3D11_SAMPLER_DESC& o ) :
        D3D11_SAMPLER_DESC( o )
    {}
    explicit CD3D11_SAMPLER_DESC( CD3D11_DEFAULT )
    {
        Filter = D3D11_FILTER_MIN_MAG_MIP_LINEAR;
        AddressU = D3D11_TEXTURE_ADDRESS_CLAMP;
        AddressV = D3D11_TEXTURE_ADDRESS_CLAMP;
        AddressW = D3D11_TEXTURE_ADDRESS_CLAMP;
        MipLODBias = 0;
        MaxAnisotropy = 1;
        ComparisonFunc = D3D11_COMPARISON_NEVER;
        BorderColor[ 0 ] = 1.0f;
        BorderColor[ 1 ] = 1.0f;
        BorderColor[ 2 ] = 1.0f;
        BorderColor[ 3 ] = 1.0f;
        MinLOD = -3.402823466e+38F; // -FLT_MAX
        MaxLOD = 3.402823466e+38F; // FLT_MAX
    }
    explicit CD3D11_SAMPLER_DESC(
        D3D11_FILTER filter,
        D3D11_TEXTURE_ADDRESS_MODE addressU,
        D3D11_TEXTURE_ADDRESS_MODE addressV,
        D3D11_TEXTURE_ADDRESS_MODE addressW,
        FLOAT mipLODBias,
        UINT maxAnisotropy,
        D3D11_COMPARISON_FUNC comparisonFunc,
        _In_reads_opt_( 4 ) const FLOAT* borderColor, // RGBA
        FLOAT minLOD,
        FLOAT maxLOD )
    {
        Filter = filter;
        AddressU = addressU;

        MaxAnisotropy = maxAnisotropy;
        ComparisonFunc = comparisonFunc;
        const float defaultColor[ 4 ] = { 1.0f, 1.0f, 1.0f, 1.0f };
        if (!borderColor) borderColor = defaultColor;
        BorderColor[ 0 ] = borderColor[ 0 ];
        BorderColor[ 1 ] = borderColor[ 1 ];
        BorderColor[ 2 ] = borderColor[ 2 ];
        BorderColor[ 3 ] = borderColor[ 3 ];
        MinLOD = minLOD;
        MaxLOD = maxLOD;
    }
    ~CD3D11_SAMPLER_DESC() {}
    operator const D3D11_SAMPLER_DESC&() const { return *this; }
};
