Struct Ray 

pub struct Ray {
    pub origin: Vec3,
    pub direction: Vec3,
    pub max_t: Real,
}

A ray in 3D space defined by an origin and a unit-direction vector.

Fields

origin: Vec3

Ray origin in world space.

direction: Vec3

Unit direction vector.

max_t: Real

Maximum ray length (use f64::MAX for infinite rays).

Implementations

impl Ray

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

Create a new ray. direction is normalised internally.

pub fn new_bounded(origin: Vec3, direction: Vec3, max_t: Real) -> Self

Create a ray with an explicit maximum extent.

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

Evaluate the point at parameter t: origin + t * direction.

pub fn from_to(from: Vec3, to: Vec3) -> Self

Create a ray from from toward to, with length = distance(from, to).

Trait Implementations

impl Clone for Ray

fn clone(&self) -> Ray

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Ray

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

Formats the value using the given formatter.
