Struct Scene 

pub struct Scene {
    pub triangles: Vec<Triangle>,
    pub materials: Vec<Material>,
    pub lights: Vec<PointLight>,
    pub area_lights: Vec<AreaLight>,
    pub bvh: Option<Bvh>,
}

A simple ray-traced scene.

Fields

triangles: Vec<Triangle>

Scene triangles.

materials: Vec<Material>

Scene materials.

lights: Vec<PointLight>

Point lights.

area_lights: Vec<AreaLight>

Area lights.

bvh: Option<Bvh>

Prebuilt BVH (None until built).

Implementations

impl Scene

pub fn new() -> Self

Create a new empty scene.

pub fn add_material(&mut self, mat: Material) -> u32

Add a material and return its index.

pub fn add_triangle(&mut self, tri: Triangle)

Add a triangle.

pub fn add_light(&mut self, light: PointLight)

Add a point light.

pub fn build_bvh(&mut self)

Build the BVH over the current triangles.

pub fn add_box(&mut self, center: [f64; 3], hs: [f64; 3], material_id: u32)

Add a unit box (12 triangles) centered at center with half-size hs.

pub fn add_quad( &mut self, v0: [f64; 3], v1: [f64; 3], v2: [f64; 3], v3: [f64; 3], material_id: u32, )

Add a planar quad (2 triangles).

pub fn intersect<'a>(&'a self, ray: &Ray) -> Option<(HitRecord, &'a Triangle)>

Intersect the scene with a ray using the prebuilt BVH.

Trait Implementations

impl Clone for Scene

fn clone(&self) -> Scene

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Scene

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

Formats the value using the given formatter.

impl Default for Scene

fn default() -> Scene

Returns the “default value” for a type.
