Fields

spheres: Vec<Sphere>

Sphere primitives in the scene.

triangles: Vec<Triangle>

Triangle primitives in the scene.

lights: Vec<PointLight>

Point lights in the scene.

materials: Vec<Material>

Material list shared by all primitives.

sky_top: [f32; 3]

Background (sky) gradient top colour.

sky_bottom: [f32; 3]

Background (sky) gradient bottom colour.

Implementations
