Learning Event 1:
DEFINE PERSPECTIVE
1. In the following section you will be shown how to construct various
types of perspective projections. A thorough understanding of perspective
will equip you with a more acute sense of observation and feeling for form
and will help you in making your drawings more convincing and realistic.
2. Perspective drawings are pictorial one-view representations which depict
a scene as it might appear to the eye. Thus, they are easier to comprehend
at a glance than drawings made in orthographic projection.
When
constructing these drawings, imagine a vertical plane placed between the eye
and the object to be drawn. This imaginary plane is the plane of projection
and in perspective is known as the "picture plane".
3. The simplest method of making a perspective drawing is to make a tracing
on a piece of glass. That is, you place a pane of glass between you and the
object and trace all visible edges of the object. The pane of glass in this
case is your picture plane.
Even though this method may be rather
impractical, it does illustrate some of the principles of perspective. In a
real situation your paper takes the place of the glass, and instead of
tracing your drawing, you project it.
4. One of the most important items in perspective drawing is the "station
point."
Actually, the "station point" represents the position of the
observer's eyes.
Therefore, the position of the station point greatly
influences the perspective. For example, a house would look much different
