Vocabularygpu.stateClass descriptionstencil-ops are set as part of a
stencil-mode and determine how the stencil buffer is modified by incoming fragments.
| • | op-keep leaves the stencil buffer value unchanged. |
| • | op-zero sets the stencil buffer value to zero. |
| • | op-replace sets the stencil buffer value to the reference value. |
| • | op-invert bitwise NOTs the stencil buffer value. |
| • | op-inc-sat adds one to the stencil buffer value, leaving it unchanged if it is already the maximum storable value. |
| • | op-dec-sat subtracts one from the stencil buffer value, leaving it unchanged if it is already zero. |
| • | op-inc-wrap adds one to the stencil buffer value, wrapping the value to zero if it was the maximum storable value. |
| • | op-dec-wrap subtracts one from the stencil buffer value, wrapping the value to the maximum storable value if it was zero. |
