Composing a 3D scene is a lot like composing software. The objects in the scene are like individual functions that were authored separately for a specific purposes. Some 3D objects can be reused in other scenes, and sometimes it's only specific to that scene. Over time you build up a catalog of objects, textures, and characters, just as a software developer builds up a catalog of code objects. The action in the scene is the execution of the program, and the camera's view is where the output of the program is being directed to. And just as software has bugs and hacks, so too 3D scenes have glitches, shortcuts, hacks, and areas that are under construction.
