Trait FragmentShader 

pub trait FragmentShader<Var> {
    // Required method
    fn shade_fragment(&self, frag: Frag<Var>) -> Option<Color4>;
}

Trait for fragment shaders, used to compute the color of each individual pixel, or fragment, rendered.

Type parameters

• Var: The varying of the input fragment.

Required Methods

fn shade_fragment(&self, frag: Frag<Var>) -> Option<Color4>

Computes the color of frag. Returns either Some(color), or None if the fragment should be discarded.

Panics

shade_fragment should never panic.
