texture mapping are simple and by applying them
to simple objects one acquires the foundation for
mapping more complex objects.

discussion of how to model characters and the
interiors of buildings. However, once one gains
proficiency modeling the exterior objects of a
virtual world, these same skills can be applied to
modeling interiors and even characters. In fact,
one can model any object that can be conceived
as collection of stacked boxes.
For example, the human head is one of the
most complex objects to model. Yet by starting
with a box and adding appropriate cuts and extru-
sions, one can create a reasonable approximation,
particularly after adding a smoothing operator to

FUTURe DIReCTIONS

I have covered how to develop a basic virtual
world consisting of a terrain, sky dome, asphalt
jungle (roads, gutters, sidewalks), and buildings.
Conspicuously missing from this chapter is a
