Scene

Scene deep inside, is a container over hittable_list class with a create_scene() function which iterates over a list of objects which are later passed to Hittable_list::add().

void Scene::setup(std::vector<std::shared_ptr<Hittable>> objects) {
    vec_Obj_objects = objects;
}

Hittable_list& Scene::create_scene() {

    for (auto itr = vec_Obj_objects.begin(); itr != vec_Obj_objects.end(); itr++) {
        HL_world.add(*itr);
    }

    return HL_world;
}
