Struct tinyraytracer::blocks::Rectangle2D

pub struct Rectangle2D {
    width: Vec3,
    height: Vec3,
    plane: Plane,
    material: Material,
}

2D rectangle in a 3D space

Fields

width: Vec3

height: Vec3

plane: Plane

material: Material

Implementations

impl Rectangle2D

pub fn new(
    origin: Vec3,
    center: Vec3,
    side_dir: Vec3,
    material: Material
) -> Self

We need 3 points to define a plane. Here we use two points on a plane and a vector that is used as the side of the rectangle.

Trait Implementations

impl Debug for Rectangle2D

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

Formats the value using the given formatter.

impl RayCollision for Rectangle2D

fn ray_intersect(&self, ray: &Ray) -> HitPoint

This is easy. We look for plane-ray intersection and check if it is withing the rectangle

fn collision_normal(&self, hit_point: Vec3) -> Vec3

fn collision_material(&self, hit_point: Vec3) -> Material
