Struct vek::geom::repr_simd::Ray

pub struct Ray<T> {
    pub origin: Vec3<T>,
    pub direction: Vec3<T>,
}

3D ray, represented by a starting point and a normalized direction vector.

Fields

origin: Vec3<T>

The ray's starting point.

direction: Vec3<T>

The ray's direction. Methods expect it to be normalized.

Implementations

impl<T: Real + Add<T, Output = T>> Ray<T>

pub fn new(origin: Vec3<T>, direction: Vec3<T>) -> Self

Creates a Ray from a starting point and direction.

This doesn't check if direction is normalized, because either you know it is, or it isn't and maybe it doesn't matter for your use case.

pub fn triangle_intersection(&self, tri: [Vec3<T>; 3]) -> Option<T>

Tests if this ray intersects the given triangle, returning the distance from the ray's origin along its direction where the intersection lies.

If the returned value is Some(x) where x < EPSILON, then you should assume there was a line intersection, NOT a ray intersection.

This uses the Möller–Trumbore intersection algorithm.
