This paper investigates the visualization of geometric algorithms. We
discuss how limiting the domain makes it possible to create a system
that enables others to use it easily. Knowledge about the domain can
be very helpful in building a system which automates large parts of
the user's task. A system can be designed to isolate the user from any
concern about how graphics is done. The application need only specify
``what'' happens and need not be concerned with ``how'' to make it
happen on the screen. We develop a conceptual model and a framework
for experimenting with it. We also present a system, GASP, which
implements this model. GASP allows quick generation of
three-dimensional geometric algorithm visualizations, even for highly
complex algorithms. It also provides a visual debugging facility for
geometric computing. We show the utility of GASP by presenting a
variety of examples.
