Struct Ray3 

pub struct Ray3 {
    pub origin: [f64; 3],
    pub direction: [f64; 3],
}

A 3D ray with origin and (pre-normalized) direction.

Fields

origin: [f64; 3]

Ray origin.

direction: [f64; 3]

Ray direction (should be normalized).

Implementations

impl Ray3

pub fn new(origin: [f64; 3], direction: [f64; 3]) -> Self

Create a new ray. Direction is normalized.

pub fn at(&self, t: f64) -> [f64; 3]

Point at parameter t: P(t) = origin + t * direction.

pub fn intersect_sphere(&self, center: [f64; 3], radius: f64) -> Option<f64>

Intersect ray with a sphere. Returns nearest positive t, or None.

pub fn intersect_aabb(&self, aabb: &Aabb3) -> Option<(f64, f64)>

Intersect ray with an AABB (slab method). Returns (t_min, t_max) or None.

pub fn intersect_triangle( &self, v0: [f64; 3], v1: [f64; 3], v2: [f64; 3], ) -> Option<(f64, f64, f64)>

Intersect ray with a triangle using the Möller–Trumbore algorithm. Returns (t, u, v) where (u,v) are barycentric coordinates, or None.
