In Chapter 22, we examined three worlds. All of them were built primarily or entirely by hand, without the use of 3d Modelers or tookits. Make no mistake: authoring tools have their place. However, the amount of control and compactness you can achieve by hand-editing VRML has yet to be matched by any of the available tools. This will change eventually, but in the meantime, you should seriously consider doing it by hand. If nothing else, you'll learn a lot about how VRML works.
