Of so many dimensions. For example:
a line is a one-dimensional object; a plane, like a sheet of paper
with no thickness, is a two dimensional object; and ordinary objects
such as tea cups are three-dimensional. Time is often considered
as a fourth dimension giving rise to the phrase `four dimensional
space-time'. Physicists and mathematicians also consider
objects and spaces with more dimensions which may or may
not include time.
discrete
Divided into a finite number sections or levels. An example
would be an approximation to a smooth curve draw with a set of straight
lines. Triangulations are discrete models
of surfaces.
