VkBlendOp - Framebuffer blending operations

Description

The semantics of each basic blend operations is described in the table below:

BlendOp	RGB Components	Alpha Component
BLEND_OP_ADD	R = Rs0 × Sr + Rd × Dr G = Gs0 × Sg + Gd × Dg B = Bs0 × Sb + Bd × Db	A = As0 × Sa + Ad × Da
BLEND_OP_SUBTRACT	R = Rs0 × Sr - Rd × Dr G = Gs0 × Sg - Gd × Dg B = Bs0 × Sb - Bd × Db	A = As0 × Sa - Ad × Da
BLEND_OP_REVERSE_SUBTRACT	R = Rd × Dr - Rs0 × Sr G = Gd × Dg - Gs0 × Sg B = Bd × Db - Bs0 × Sb	A = Ad × Da - As0 × Sa
BLEND_OP_MIN	R = min(Rs0,Rd) G = min(Gs0,Gd) B = min(Bs0,Bd)	A = min(As0,Ad)
BLEND_OP_MAX	R = max(Rs0,Rd) G = max(Gs0,Gd) B = max(Bs0,Bd)	A = max(As0,Ad)

Basic Blend Operations

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.
• 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.
• Sr, Sg, Sb and Sa represent the source blend factor R, G, B, and A components, respectively.
• Dr, Dg, Db and Da represent the destination blend factor R, G, B, and A components, respectively.

The blending operation produces a new set of values R, G, B and A, which are written to the framebuffer attachment. If blending is not enabled for this attachment, then R, G, B and A are assigned Rs0, Gs0, Bs0 and As0, respectively.

If the color attachment is fixed-point, the components of the source and destination values and blend factors are each clamped to [0,1] or [-1,1] respectively for an unsigned normalized or signed normalized color attachment prior to evaluating the blend operations. If the color attachment is floating-point, no clamping occurs.
