Struct crystal_ball::math::Ray

pub struct Ray {
    pub origin: Point3,
    pub direction: Vec3,
    pub last_ior: f64,
}

A ray in 3D space.

Fields

origin: Point3

The ray’s origin.

direction: Vec3

The ray’s direction.

last_ior: f64

The index of refraction of the ray’s last medium.

Implementations

impl Ray

pub fn new(origin: Point3, direction: Vec3, last_ior: f64) -> Self

Create a new Ray.

This slightly shifts origin in the positive direction (by a factor of 1e-9) to avoid problems with floating point precision.

pub fn get(&self, distance: f64) -> Point3

Return the Point3 on the Ray at the given distance.

Trait Implementations

impl Clone for Ray

fn clone(&self) -> Ray

Returns a copy 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.

impl PartialEq for Ray

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

This method tests for self and other values to be equal, and is used by ==.

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

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