VkColorBlendEquationEXT
The VkColorBlendEquationEXT structure is defined as:
typedef struct VkColorBlendEquationEXT {
VkBlendFactor srcColorBlendFactor;
VkBlendFactor dstColorBlendFactor;
VkBlendOp colorBlendOp;
VkBlendFactor srcAlphaBlendFactor;
VkBlendFactor dstAlphaBlendFactor;
VkBlendOp alphaBlendOp;
} VkColorBlendEquationEXT;
srcColorBlendFactorselects which blend factor is used to determine the source factors (Sr,Sg,Sb).dstColorBlendFactorselects which blend factor is used to determine the destination factors (Dr,Dg,Db).colorBlendOpselects which blend operation is used to calculate the RGB values to write to the color attachment.srcAlphaBlendFactorselects which blend factor is used to determine the source factor Sa.dstAlphaBlendFactorselects which blend factor is used to determine the destination factor Da.alphaBlendOpselects which blend operation is use to calculate the alpha values to write to the color attachment.
