Enum golem::depth::DepthTestFunction

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

Function used to compare each incoming pixel depth value with the depth value present in the depth buffer

"Depth value" is, roughly, how far away the pixel is from the camera; you'll almost always want DepthTestFunction::Less (which is the default).

Variants

Never

Pixel is never drawn

Less

Pixel is drawn if it's depth value is less than the stored one

Equal

Pixel is drawn if it's depth value is equal to the stored one

LessOrEqual

Pixel is drawn if it's depth value is less than or equal to the stored one

Greater

Pixel is drawn if it's depth value is greater than the stored one

NotEqual

Pixel is drawn if it's depth value is not equal to the stored one

GreaterOrEqual

Pixel is drawn if it's depth value is greater than or equal to the stored one

Always

Pixel is always drawn
