Struct HitRecord 

pub struct HitRecord {
    pub t: f64,
    pub point: Point3<f64>,
    pub normal: Unit<Vector3<f64>>,
    pub front_face: bool,
    pub material: MaterialId,
}

Record of a ray-surface intersection.

Fields

t: f64

Distance along the ray to the hit point.

point: Point3<f64>

World-space hit position.

normal: Unit<Vector3<f64>>

Outward-facing surface normal at the hit point.

front_face: bool

True if the ray hit the outside of the surface (front face).

material: MaterialId

Index into the scene’s material list.

Implementations

impl HitRecord

pub fn set_face_normal(&mut self, ray: &Ray, outward_normal: Unit<Vector3<f64>>)

Set the face normal based on ray direction. Ensures the normal always points against the ray.
