Implementations

impl LightSource

pub fn light_at(&self, point: Point) -> LightColor

The light at point of the plane z = 0 (not clamped).

impl LightSource

pub fn lit_at(&self, point: Point, material: &LightingMaterial) -> LightColor

The light at point of the plane z = 0 reflected by material (not clamped): the ambient light times the ambient amount, the other lights times the diffuse amount and N.L, plus their specular highlight times the specular amount.
