Sketching- Perspective

Introduction

If you can stand on a straight road and look down the road, it appears as if the sides of the road eventually narrow to one point. The center of the road vanishes when the road meets the horizon. If the road is straight enough and long enough, the sides of the road not only look like they are converging to a single point, but the road seems to appear to vanish as it meets the horizon. A similar effect occurs if you stare upward from the base of a tall building. The vertical edges of the building will appear to angle in toward each other. This effect is called perspective.

The human eye sees the world in perspective. Objects that are further away from the eye appear smaller, and edges appear to recede into the distance. Perspective sketches depict objects in much the same way that the human eye sees the world.

There are three different types of perspective drawings: one-point, two-point, andthree-point perspective. The different types of sketches are frequently used by architects, industrial designers, and illustrators when representing large scale objects or environments in which the effect of distance must be taken into consideration.

In this activity, you will practice your sketching skills by generating perspective views based on provided isometric views of objects. You will also apply your skills by creating one-point and two-point perspective of other imagined or real objects that you choose.

Equipment

•

Grid paper or engineering notebook

•

Pencil and/or pen

•

Puzzle cube puzzle pieces

•

Various objects

Procedure

Study the object represented in the isometric views below. Use the vanishing point and horizon line indicated to lay out light construction lines and create a one-point perspective sketch of the object within the given box. The perspective sketch must show the object in a top, left side, front view orientation. Delineate the visible edges of the sketch with heavy object lines. DO NOT ERASE YOUR CONSTRUCTION LINES. Add tonal shading to the sketch when finished.
