noun of this Website suggests, the object of interest is the study of the geometry that is used to draw perspective. It was
during Renaissance time when the theoretical principles of perspective were set down, which also were put into practice. Today,
the way such principles are applied is what we call methods.
At first, all methods were applied by means of geometry; a time in
which triangle rulers, pencils and paper sufficed for all needs. But then, in the late 1970s, computer graphics come up as
a new tool for drawing perspective. A tool very useful, no doubt, but it does not replace the human touch of pencils. There
is no reason to debate which one is the best, since both hand drawing and computer graphics are used for different purposes.
