VkColorBlendEquationEXT
The VkColorBlendEquationEXT
structure is defined as:
typedef struct VkColorBlendEquationEXT {
VkBlendFactor srcColorBlendFactor;
VkBlendFactor dstColorBlendFactor;
VkBlendOp colorBlendOp;
VkBlendFactor srcAlphaBlendFactor;
VkBlendFactor dstAlphaBlendFactor;
VkBlendOp alphaBlendOp;
} VkColorBlendEquationEXT;
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.
