C Specification

The VkColorBlendEquationEXT structure is defined as:

// Provided by VK_EXT_extended_dynamic_state3, VK_EXT_shader_object
typedef struct VkColorBlendEquationEXT {
    VkBlendFactor    srcColorBlendFactor;
    VkBlendFactor    dstColorBlendFactor;
    VkBlendOp        colorBlendOp;
    VkBlendFactor    srcAlphaBlendFactor;
    VkBlendFactor    dstAlphaBlendFactor;
    VkBlendOp        alphaBlendOp;
} VkColorBlendEquationEXT;

Members

  • srcColorBlendFactor selects which blend factor is used to determine the source factors (Sr,Sg,Sb).

  • dstColorBlendFactor selects which blend factor is used to determine the destination factors (Dr,Dg,Db).

  • colorBlendOp selects which blend operation is used to calculate the RGB values to write to the color attachment.

  • srcAlphaBlendFactor selects which blend factor is used to determine the source factor Sa.

  • dstAlphaBlendFactor selects which blend factor is used to determine the destination factor Da.

  • alphaBlendOp selects which blend operation is use to calculate the alpha values to write to the color attachment.
