C Specification
Possible values of the failOp, passOp, and depthFailOp
members of VkStencilOpState, specifying what happens to the stored
stencil value if this or certain subsequent tests fail or pass, are:
// Provided by VK_VERSION_1_0
typedef enum VkStencilOp {
VK_STENCIL_OP_KEEP = 0,
VK_STENCIL_OP_ZERO = 1,
VK_STENCIL_OP_REPLACE = 2,
VK_STENCIL_OP_INCREMENT_AND_CLAMP = 3,
VK_STENCIL_OP_DECREMENT_AND_CLAMP = 4,
VK_STENCIL_OP_INVERT = 5,
VK_STENCIL_OP_INCREMENT_AND_WRAP = 6,
VK_STENCIL_OP_DECREMENT_AND_WRAP = 7,
} VkStencilOp;Description
-
VK_STENCIL_OP_KEEP keeps the current value.
-
VK_STENCIL_OP_ZERO sets the value to 0.
-
VK_STENCIL_OP_REPLACE sets the value to
reference. -
VK_STENCIL_OP_INCREMENT_AND_CLAMP increments the current value and clamps to the maximum representable unsigned value.
-
VK_STENCIL_OP_DECREMENT_AND_CLAMP decrements the current value and clamps to 0.
-
VK_STENCIL_OP_INVERT bitwise-inverts the current value.
-
VK_STENCIL_OP_INCREMENT_AND_WRAP increments the current value and wraps to 0 when the maximum value would have been exceeded.
-
VK_STENCIL_OP_DECREMENT_AND_WRAP decrements the current value and wraps to the maximum possible value when the value would go below 0.
For purposes of increment and decrement, the stencil bits are considered as an unsigned integer.
