Public Attributes

Bool AlphaToCoverageEnable
 Specifies whether to use alpha-to-coverage as a multisampling technique when setting a pixel to a render target. Default value: False.
 
Bool IndependentBlendEnable
 Specifies whether to enable independent blending in simultaneous render targets. If set to False, only RenderTargets[0] is used. Default value: False.
 
RenderTargetBlendDesc RenderTargets [MaxRenderTargets]
 An array of RenderTargetBlendDesc structures that describe the blend states for render targets.
 

Static Public Attributes

static const int MaxRenderTargets = 8
 Constant member defining the maximum number of render targets.
 

Detailed Description

Blend state description.

This structure describes the blend state and is part of the GraphicsPipelineDesc.

Constructor & Destructor Documentation

Diligent::BlendStateDesc::BlendStateDesc ( )

Constructor initializes structure members with default values.

Member Default value
AlphaToCoverageEnable False
IndependentBlendEnableFalse

Members of RenderTargets[] are initialized with default values by RenderTargetBlendDesc::RenderTargetBlendDesc()

bool Diligent::BlendStateDesc::operator== ( const BlendStateDesc &  RHS) const

Comparison operator tests if two structures are equivalent.

Parameters
[in]RHS- reference to the structure to perform comparison with
Returns
  • True if all members are of the two structures equal.
Note
The operator performs bitwise comparison of the two structures. That is if for instance both structures have IndependentBlendEnable set to False, but differ in render target other than 0, the operator will return False even though the two blend states created from these structures will be identical.
  • False otherwise
