VkLogicOp - Framebuffer logical operations

Description

The logical operations supported by Vulkan are summarized in the following table in which

• ¬ is bitwise invert,
• ∧ is bitwise and,
• ∨ is bitwise or,
• ⊕ is bitwise exclusive or,
• s is the fragment’s Rs0, Gs0, Bs0 or As0 component value for the fragment output corresponding to the color attachment being updated, and
• d is the color attachment’s R, G, B or A component value:

Mode	Operation
LOGIC_OP_CLEAR	0
LOGIC_OP_AND	s ∧ d
LOGIC_OP_AND_REVERSE	s ∧ ¬ d
LOGIC_OP_COPY	s
LOGIC_OP_AND_INVERTED	¬ s ∧ d
LOGIC_OP_NO_OP	d
LOGIC_OP_XOR	s ⊕ d
LOGIC_OP_OR	s ∨ d
LOGIC_OP_NOR	¬ (s ∨ d)
LOGIC_OP_EQUIVALENT	¬ (s ⊕ d)
LOGIC_OP_INVERT	¬ d
LOGIC_OP_OR_REVERSE	s ∨ ¬ d
LOGIC_OP_COPY_INVERTED	¬ s
LOGIC_OP_OR_INVERTED	¬ s ∨ d
LOGIC_OP_NAND	¬ (s ∧ d)
LOGIC_OP_SET	all 1s

Logical Operations

The result of the logical operation is then written to the color attachment as controlled by the component write mask, described in Blend Operations.
