Struct rustracer::world::World

pub struct World {
    shapes: Vec<Box<dyn RayIntersection>>,
}

A class holding a list of shapes (e.g. Plane, Sphere).

You can add shapes to a world using add.
Typically, you call ray_intersection to check whether a light ray intersects any of the shapes in the world.

Fields

shapes: Vec<Box<dyn RayIntersection>>

A std::vec::Vec of std::boxed::Box-ed shapes that implement RayIntersection trait (vector of traits).

Implementations

impl World

pub fn add(&mut self, shape: Box<dyn RayIntersection>)

Append a new boxed shape to this World.

pub fn ray_intersection(&self, ray: Ray) -> Option<HitRecord>

Determine whether a ray intersects any of the objects in this World.

Return HitRecord wrapped inside std::option::Option.

Trait Implementations

impl Debug for World

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

Formats the value using the given formatter.

impl Default for World

fn default() -> World

Returns the “default value” for a type.
