The first use of the word perspective occurred in the late 14th century. The etymology of this word is traced by Webster’s Revised Unabridged Dictionary.

from Old French perspective, from Medieval Latin perspectiva ars “science of optics,” from feminine of perspectivus “of sight, optical” from past participle stem of perspicere “inspect, look through,” from per- “through” + specere “look at.” Originally “optics,” sense of

a. The relationship of aspects of a subject to each other and to a whole: a perspective of history; a need to view the problem in the proper perspective.

There is no doubt perspective has many definitions and many uses, whether its used in engineering, art or in computer terms. In any case, it is important to know what the correct usage of the word is to correspond to a statement. Take the first example, for instance. When the reporter asked the coach about his perspective on the game, the coach did not say, “I think it was a second person perspective since I was viewing the game as a spectator”. Perspective is best summed up by Oliver Goldsmith, an Anglo-Irish author from 1730 to 1774, who declared, “Perspective an opening which the view of life can be seen”.

c. The ability to perceive things in their actual interrelations or comparative importance: tried to keep my perspective throughout the crisis.

The next definition of perspective relates to my graphic engineering class. The American Heritage Dictionary states, “[perspective] the appearance of an objects in depth as perceived by normal binocular vision.” This sounds complicated but can be summarized as objects viewed in three dimensions, and this is also known as isometric perspective. An important skill in graphic engineering is to know how to draw objects in perspective. Thus, the manufacturer of the object can clearly see, in three dimension, what the object looks like.
