Struct tinyraytracer::blocks::Ray

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

What is the difference between a Vec3 and a Ray? After all Vec3 is a Ray that starts at the origin. Well Ray is infinite length. That’s why the direction can be unit norm. Vec3 length is finite (it’s norm).

Fields

origin: Vec3

direction: Vec3

Unit norm direction vector

Implementations

impl Ray
