This chapter covers the theory of perspective projections, the
interrelationship of linear and aerial perspective, and the opposing principle
of reverse perspective. Definitions of one-, two-, and three-point perspective
should enable you to create perspective drawings. The procedures for
mechanical construction of perspective drawings using the plan-view method
are discussed as well as a brief description of line measurement. The section
on general practices in constructing perspective drawings should simplify
your task of creating realistic perspective drawings of any object in front of
Perspective is not the easiest part of the DM rating to learn. Perspective is
the most telling feature of a drawing when assessing the talents of a DM.
Each one of us has seen drawings that superficially appear well constructed.
On closer inspection, certain details make us aware that the DM was not as
talented as was first thought. The most tattle-tell element in a perspective
drawing is the way a circle on a plane not parallel to the plane of projection
is drawn. Pay close attention to the angle of the major to minor axis of an
ellipse representing a circle in perspective. Strive to get the details right.
Perspective projections are often confused with parallel projections covered
in the next chapter. Take the time to truly understand the material in this
chapter before moving on to the next chapter.
