The word "geometry" literally means earth measure; the
classical study of geometry concerns the properties, measurement and
relationship of points, lines and figures in space. The notion of a
geometric model is hardly new; geometric models were used 5000 years
ago for astronomy and engineering by the earliest Egyptian
civilization.
The geometric world model has three roles:
Assumption: The vision world model should be three dimensional.
Assumption: The vision world model should be able to represent:
1. surfaces of opaque objects.
