Enum Shader

pub enum Shader {
    Blinn(Blinn),
    Constant(ConstantFx),
    Lambert(Lambert),
    Phong(Phong),
}

A shader element.

Variants

Blinn(Blinn)

Produces a specularly shaded surface with a Blinn BRDF approximation.

Constant(ConstantFx)

Produces a constantly shaded surface that is independent of lighting.

Lambert(Lambert)

Produces a diffuse shaded surface that is independent of lighting.

Phong(Phong)

Produces a specularly shaded surface where the specular reflection is shaded according the Phong BRDF approximation.
