Enum glium::draw_parameters::StencilOperation [−] [src]

pub enum StencilOperation {
    Keep,
    Zero,
    Replace,
    Increment,

Specificies which operation the GPU will do depending on the result of the stencil test.

Variants

`Keep`	Keeps the value currently in the stencil buffer.
`Zero`	Writes zero in the stencil buffer.
`Replace`	Writes the reference value (`stencil_reference_value_clockwise` or `stencil_reference_value_counter_clockwise`) in the stencil buffer.
`Increment`	Increments the value currently in the stencil buffer. If the value is the maximum, don't do anything.
`IncrementWrap`	Increments the value currently in the stencil buffer. If the value is the maximum, wrap to `0`.
`Decrement`	Decrements the value currently in the stencil buffer. If the value is `0`, don't do anything.
`DecrementWrap`	Decrements the value currently in the stencil buffer. If the value is `0`, wrap to `-1`.
`Invert`	Inverts each bit of the value.
