Enum luminance::depth_test::DepthComparison

pub enum DepthComparison {
    Never,
    Always,
    Equal,
    NotEqual,
    Less,
    LessOrEqual,
    Greater,
    GreaterOrEqual,
}

Depth comparison to perform while depth test. a is the incoming fragment’s depth and b is the fragment’s depth that is already stored.

Variants

Never

Depth test never succeeds.

Always

Depth test always succeeds.

Equal

Depth test succeeds if a == b.

NotEqual

Depth test succeeds if a != b.

Less

Depth test succeeds if a < b.

LessOrEqual

Depth test succeeds if a <= b.

Greater

Depth test succeeds if a > b.

GreaterOrEqual

Depth test succeeds if a >= b.
