Expand description
Specificies which operation the GPU will do depending on the result of the stencil test.
Variants§
Keep = 7_680
Keeps the value currently in the stencil buffer.
Zero = 0
Writes zero in the stencil buffer.
Replace = 7_681
Writes the reference value (stencil_reference_value_clockwise
or
stencil_reference_value_counter_clockwise
) in the stencil buffer.
Increment = 7_682
Increments the value currently in the stencil buffer. If the value is the maximum, don’t do anything.
IncrementWrap = 34_055
Increments the value currently in the stencil buffer. If the value is the
maximum, wrap to 0
.
Decrement = 7_683
Decrements the value currently in the stencil buffer. If the value is 0
,
don’t do anything.
DecrementWrap = 34_056
Decrements the value currently in the stencil buffer. If the value is 0
,
wrap to -1
.
Invert = 5_386
Inverts each bit of the value.
