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.
