Struct tray_rust::linalg::ray::Ray

pub struct Ray {
    pub o: Point,

}

Ray is a standard 3D ray, starting at origin o and heading in direction d The min and max points along the ray can be specified with min_t and max_t depth is the recursion depth of the ray

Fields

o: Point

Origin of the ray

d: Vector

Direction the ray is heading

min_t: f32

Point along the ray that the actual ray starts at, p = o + min_t * d

max_t: f32

Point along the ray at which it stops, will be inf if the ray is infinite

depth: u32

Recursion depth of the ray

time: f32

Time point sampled by this ray

Methods

impl Ray

pub fn new(o: &Point, d: &Vector, time: f32) -> Ray

Create a new ray from o heading in d with infinite length

pub fn segment(o: &Point, d: &Vector, min_t: f32, max_t: f32, time: f32) -> Ray

Create a new segment ray from o + min_t * d to o + max_t * d

pub fn child(&self, o: &Point, d: &Vector) -> Ray

Create a child ray from the parent starting at o and heading in d

pub fn child_segment(
    &self,
    o: &Point,
    d: &Vector,
    min_t: f32,
    max_t: f32
) -> Ray

Create a child ray segment from o + min_t * d to o + max_t * d

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

Evaulate the ray equation at some t value and return the point returns result of self.o + t * self.d
