Module vulkano::pipeline::graphics::color_blend

source ·
Expand description

Configures how the color output of the fragment shader is written to the attachment.

Blending in details

There are three kinds of color attachments for the purpose of blending:

  • Attachments with a floating-point or fixed point format.
  • Attachments with a (non-normalized) integer format.
  • Attachments with a normalized integer format.

For floating-point and fixed-point formats, the blending operation is applied. For integer formats, the logic operation is applied. For normalized integer formats, the logic operation will take precedence if it is activated, otherwise the blending operation is applied.

Structs

  • AttachmentBlend
    Describes how the blending system should behave for an attachment.
  • ColorBlendAttachmentState
    Describes how a framebuffer color attachment is handled in the pipeline during the color blend stage.
  • ColorBlendState
    Describes how the color output of the fragment shader is written to the attachment. See the documentation of the blend module for more info.
  • ColorBlendStateFlags
    Flags specifying additional properties of the color blend state.
  • ColorComponents
    A mask specifying color components that can be written to a framebuffer attachment.

Enums

  • BlendFactor
    The operation that takes source (output from the fragment shader), destination (value currently in the framebuffer attachment) and blend_constant input values, and produces new inputs to be fed to BlendOp.
  • BlendOp
    The arithmetic operation that is applied between the source and destination component values, after the appropriate BlendFactor is applied to both.
  • LogicOp
    Which logical operation to apply to the output values.
