Struct Ray3 

pub struct Ray3 {
    pub origin: Vec3,
    pub direction: Vec3,
}

A normalized 3D ray.

Fields

origin: Vec3

Ray origin.

direction: Vec3

Normalized ray direction.

Implementations

impl Ray3

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

Creates a ray and normalizes the direction.

pub fn at(self, t: f32) -> Vec3

Returns the point at parametric distance t.

pub fn intersect_aabb(self, aabb: Aabb) -> Option<f32>

Intersects this ray with an AABB and returns nearest non-negative t.

pub fn intersect_sphere(self, center: Vec3, radius: f32) -> Option<f32>

Intersects this ray with a sphere and returns nearest non-negative t.

pub fn intersect_bounding_sphere(self, sphere: Sphere) -> Option<f32>

Intersects this ray with a sphere and returns nearest non-negative t.

pub fn intersect_triangle( self, a: Vec3, b: Vec3, c: Vec3, ) -> Option<(f32, Vec2)>

Intersects this ray with a triangle using Moller-Trumbore.

Returns (t, Vec2::new(u, v)), where u and v are barycentric coordinates and w = 1 - u - v.

Trait Implementations

impl Clone for Ray3

fn clone(&self) -> Ray3

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Ray3

impl Debug for Ray3

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Ray3

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Ray3

fn eq(&self, other: &Ray3) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
