newtype BlendFactor Source #

VkBlendFactor - Framebuffer blending factors

Description

The semantics of each enum value is described in the table below:

BlendFactor RGB Blend Factors (Sr,Sg,Sb) or (Dr,Dg,Db) Alpha Blend Factor (Sa or Da)
BLEND_FACTOR_ZERO (0,0,0) 0
BLEND_FACTOR_ONE (1,1,1) 1
BLEND_FACTOR_SRC_COLOR (Rs0,Gs0,Bs0) As0
BLEND_FACTOR_ONE_MINUS_SRC_COLOR (1-Rs0,1-Gs0,1-Bs0) 1-As0
BLEND_FACTOR_DST_COLOR (Rd,Gd,Bd) Ad
BLEND_FACTOR_ONE_MINUS_DST_COLOR (1-Rd,1-Gd,1-Bd) 1-Ad
BLEND_FACTOR_SRC_ALPHA (As0,As0,As0) As0
BLEND_FACTOR_ONE_MINUS_SRC_ALPHA (1-As0,1-As0,1-As0) 1-As0
BLEND_FACTOR_DST_ALPHA (Ad,Ad,Ad) Ad
BLEND_FACTOR_ONE_MINUS_DST_ALPHA (1-Ad,1-Ad,1-Ad) 1-Ad
BLEND_FACTOR_CONSTANT_COLOR (Rc,Gc,Bc) Ac
BLEND_FACTOR_ONE_MINUS_CONSTANT_COLOR (1-Rc,1-Gc,1-Bc) 1-Ac
BLEND_FACTOR_CONSTANT_ALPHA (Ac,Ac,Ac) Ac
BLEND_FACTOR_ONE_MINUS_CONSTANT_ALPHA (1-Ac,1-Ac,1-Ac) 1-Ac
BLEND_FACTOR_SRC_ALPHA_SATURATE (f,f,f); f = min(As0,1-Ad) 1
BLEND_FACTOR_SRC1_COLOR (Rs1,Gs1,Bs1) As1
BLEND_FACTOR_ONE_MINUS_SRC1_COLOR (1-Rs1,1-Gs1,1-Bs1) 1-As1
BLEND_FACTOR_SRC1_ALPHA (As1,As1,As1) As1
BLEND_FACTOR_ONE_MINUS_SRC1_ALPHA (1-As1,1-As1,1-As1) 1-As1

Blend Factors

In this table, the following conventions are used:

  • Rs0,Gs0,Bs0 and As0 represent the first source color R, G, B, and A components, respectively, for the fragment output location corresponding to the color attachment being blended.
  • Rs1,Gs1,Bs1 and As1 represent the second source color R, G, B, and A components, respectively, used in dual source blending modes, for the fragment output location corresponding to the color attachment being blended.
  • Rd,Gd,Bd and Ad represent the R, G, B, and A components of the destination color. That is, the color currently in the corresponding color attachment for this fragment/sample.
  • Rc,Gc,Bc and Ac represent the blend constant R, G, B, and A components, respectively.
