D3D11_RENDER_TARGET_BLEND_DESC structure (d3d11.h)

  • Article

Describes the blend state for a render target.

Syntax

typedef struct D3D11_RENDER_TARGET_BLEND_DESC {
  BOOL           BlendEnable;
  D3D11_BLEND    SrcBlend;
  D3D11_BLEND    DestBlend;
  D3D11_BLEND_OP BlendOp;
  D3D11_BLEND    SrcBlendAlpha;
  D3D11_BLEND    DestBlendAlpha;
  D3D11_BLEND_OP BlendOpAlpha;
  UINT8          RenderTargetWriteMask;
} D3D11_RENDER_TARGET_BLEND_DESC;

Members

BlendEnable

Type: BOOL

Enable (or disable) blending.

SrcBlend

Type: D3D11_BLEND

This blend option specifies the operation to perform on the RGB value that the pixel shader outputs. The BlendOp member defines how to combine the SrcBlend and DestBlend operations.

DestBlend

Type: D3D11_BLEND

This blend option specifies the operation to perform on the current RGB value in the render target. The BlendOp member defines how to combine the SrcBlend and DestBlend operations.

BlendOp

Type: D3D11_BLEND_OP

This blend operation defines how to combine the SrcBlend and DestBlend operations.

SrcBlendAlpha

Type: D3D11_BLEND

This blend option specifies the operation to perform on the alpha value that the pixel shader outputs. Blend options that end in _COLOR are not allowed. The BlendOpAlpha member defines how to combine the SrcBlendAlpha and DestBlendAlpha operations.

DestBlendAlpha

Type: D3D11_BLEND

This blend option specifies the operation to perform on the current alpha value in the render target. Blend options that end in _COLOR are not allowed. The BlendOpAlpha member defines how to combine the SrcBlendAlpha and DestBlendAlpha operations.

BlendOpAlpha

Type: D3D11_BLEND_OP

This blend operation defines how to combine the SrcBlendAlpha and DestBlendAlpha operations.

RenderTargetWriteMask

Type: UINT8

A write mask.

Remarks

You specify an array of D3D11_RENDER_TARGET_BLEND_DESC structures in the RenderTarget member of the D3D11_BLEND_DESC structure to describe the blend states for render targets; you can bind up to eight render targets to the output-merger stage at one time.

For info about how blending is done, see the output-merger stage.

Here are the default values for blend state.

State Default Value
BlendEnable FALSE
SrcBlend D3D11_BLEND_ONE
DestBlend D3D11_BLEND_ZERO
BlendOp D3D11_BLEND_OP_ADD
SrcBlendAlpha D3D11_BLEND_ONE
DestBlendAlpha D3D11_BLEND_ZERO
BlendOpAlpha D3D11_BLEND_OP_ADD
RenderTargetWriteMask D3D11_COLOR_WRITE_ENABLE_ALL
