Motor is a project by two undergrad students at the University of Utrecht.

root.cpp: Entry point, contains many root class such as listener.

Input: Objects can add themselves as a listener to a keyevent/mouseevent using something along the lines of a responder chain.

World: Maintains scenes which on their turn have a list of entities (objects, lights, ...), and hold information on the atmosphere etc.

Renderer: Holds a reference to the object-list contained in the world object, and renders the current scene to the proper viewport.
