Struct Material 

pub struct Material {
    pub albedo: [f32; 3],
    pub kind: MaterialType,
}

A surface material with albedo colour and scattering type.

Fields

albedo: [f32; 3]

Base colour of the material (RGB in [0,1]).

kind: MaterialType

Scattering behaviour.

Implementations

impl Material

pub fn lambertian(albedo: [f32; 3]) -> Self

Create a Lambertian (diffuse) material.

pub fn metal(albedo: [f32; 3], fuzz: f32) -> Self

Create a metallic material.

pub fn dielectric(ior: f32) -> Self

Create a dielectric (glass) material.

pub fn scatter( &self, ray: &Ray, hit: &HitRecord, rng: &mut impl Rng, ) -> Option<(Ray, [f32; 3])>

Scatter a ray off this material surface.

Returns Some((scattered_ray, attenuation)) or None if absorbed.
