Introduction
A scene is represented by the <a-scene> element. The scene is the global root object, and all entities are contained within the scene.
The scene inherits from the Entity class so it inherits all of its properties, its methods, the ability to attach components, and the behavior to wait for all of its child nodes (e.g., <a-assets> and <a-entity>) to load before kicking off the render loop.
