A trait based scene abstraction.

Required Methods

fn new() -> Selfwhere Self: Sized,

fn background(&self, ray: &Ray) -> PTF3

Background color for the given ray

fn closest_hit( &self, ray: &Ray, state: &mut State, light: &mut LightSampleRec ) -> bool

Closest hit should return the state.hit_dist, state.normal and fill out the state.material as needed

fn any_hit(&self, ray: &Ray, max_dist: PTF) -> bool

Used for shadow rays.

fn camera(&self) -> &Box<dyn Camera3D>

Return the camera for the scene

fn number_of_lights(&self) -> usize

Return the number of lights in the scene

fn light_at(&self, index: usize) -> &AnalyticalLight

Return a reference for the light at the given index

Provided Methods

fn recursion_depth(&self) -> u16

The recursion depth for the path tracer

fn to_linear(&self, c: PTF3) -> PTF3
