D3D11_BLEND_DESC Structure

  • Artikel

Describes the blend state.

Syntax

typedef struct D3D11_BLEND_DESC {
  BOOL                           AlphaToCoverageEnable;
  BOOL                           IndependentBlendEnable;
  D3D11_RENDER_TARGET_BLEND_DESC RenderTarget[8];
} D3D11_BLEND_DESC;

Mitglieder

  • AlphaToCoverageEnable
    Typ: BOOL

    Determines whether or not to use alpha-to-coverage as a multisampling technique when setting a pixel to a rendertarget.

  • IndependentBlendEnable
    Typ: BOOL

    Set to TRUE to enable independent blending in simultaneous render targets. If set to FALSE, only the RenderTarget[0] members are used. RenderTarget[1..7] are ignored.

  • RenderTarget
    Typ: D3D11_RENDER_TARGET_BLEND_DESC

    An array of render-target-blend descriptions (see D3D11_RENDER_TARGET_BLEND_DESC); these correspond to the eight rendertargets that can be set to the output-merger stage at one time.

Hinweise

These are the default values for blend state.

State Default Value
AlphaToCoverageEnable FALSE
IndependentBlendEnable FALSE
RenderTarget[0].BlendEnable FALSE
RenderTarget[0].SrcBlend D3D11_BLEND_ONE
RenderTarget[0].DestBlend D3D11_BLEND_ZERO
RenderTarget[0].BlendOp D3D11_BLEND_OP_ADD
RenderTarget[0].SrcBlendAlpha D3D11_BLEND_ONE
RenderTarget[0].DestBlendAlpha D3D11_BLEND_ZERO
RenderTarget[0].BlendOpAlpha D3D11_BLEND_OP_ADD
RenderTarget[0].RenderTargetWriteMask D3D11_COLOR_WRITE_ENABLE_ALL

 

Note that D3D11_BLEND_DESC is identical to D3D10_BLEND_DESC1.

If the driver type is set to D3D_DRIVER_TYPE_HARDWARE, the feature level is set to less than or equal to D3D_FEATURE_LEVEL_9_3, and the pixel format of the render target is set to DXGI_FORMAT_R8G8B8A8_UNORM_SRGB, DXGI_FORMAT_B8G8R8A8_UNORM_SRGB, or DXGI_FORMAT_B8G8R8X8_UNORM_SRGB, the display device performs the blend in standard RGB (sRGB) space and not in linear space. However, if the feature level is set to greater than D3D_FEATURE_LEVEL_9_3, the display device performs the blend in linear space.
