Enum glium::draw_parameters::StencilTest

pub enum StencilTest {
    AlwaysPass,
    AlwaysFail,
    IfLess {
        mask: u32,
    },
    IfLessOrEqual {
        mask: u32,
    },
    IfMore {
        mask: u32,

        mask: u32,
    },
}

Specifies which comparison the GPU will do to determine whether a sample passes the stencil test. The general equation is (ref & mask) CMP (stencil & mask), where ref is the reference value (stencil_reference_value_clockwise or stencil_reference_value_counter_clockwise), CMP is the comparison chosen, and stencil is the current value in the stencil buffer.

Variants

AlwaysPass	The stencil test always passes.
AlwaysFail	The stencil test always fails.
IfLess	(ref & mask) < (stencil & mask) Fields mask The mask that is and'ed with the reference value and stencil buffer.
IfLessOrEqual	(ref & mask) <= (stencil & mask) Fields mask The mask that is and'ed with the reference value and stencil buffer.
IfMore	(ref & mask) > (stencil & mask) Fields mask The mask that is and'ed with the reference value and stencil buffer.
IfMoreOrEqual	(ref & mask) >= (stencil & mask) Fields mask The mask that is and'ed with the reference value and stencil buffer.
IfEqual	(ref & mask) == (stencil & mask) Fields mask The mask that is and'ed with the reference value and stencil buffer.
IfNotEqual	(ref & mask) != (stencil & mask) Fields mask The mask that is and'ed with the reference value and stencil buffer.
