Struct Dielectric

Source 
pub struct Dielectric {
    pub ref_idx: f64,
}
Expand description

Dielectric (refractive) material (glass, water, diamond, etc.).

Fields§

§ref_idx: f64

Index of refraction (air ≈ 1.0, glass ≈ 1.3–1.7, diamond ≈ 2.4).

Implementations§

Source§

impl Dielectric

Source

pub fn new(ref_idx: f64) -> Self

Creates a Dielectric material with the given index of refraction.

impl Material for Dielectric

Source§

fn scatter(&self, r_in: &Ray, rec: &HitRecord) -> Option<(Color, Ray)>

Returns Some((attenuation, scattered_ray)) if the ray scatters, or None if it is absorbed.
