Summary, ContinuedReviewThis chapter covers the theory of perspective projections, theinterrelationship of linear and aerial perspective, and the opposing principleof reverse perspective. Definitions of one-, two-, and three-point perspectiveshould enable you to create perspective drawings. The procedures formechanical construction of perspective drawings using the plan-view methodare discussed as well as a brief description of line measurement. The sectionon general practices in constructing perspective drawings should simplifyyour task of creating realistic perspective drawings of any object in front ofyou.CommentsPerspective is not the easiest part of the DM rating to learn. Perspective isthe 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 astalented as was first thought. The most tattle-tell element in a perspectivedrawing is the way a circle on a plane not parallel to the plane of projectionis drawn. Pay close attention to the angle of the major to minor axis of anellipse representing a circle in perspective. Strive to get the details right.Perspective projections are often confused with parallel projections coveredin the next chapter. Take the time to truly understand the material in thischapter before moving on to the next chapter.5-37
