PERSPECTIVE DRAWING

Welcome to class!

In today’s class, we will be talking about perspective drawing. Enjoy the class!

A perspective drawing is a pictorial representation of an object, as seen by an observer, through an imaginary plane called picture plane.

The observer’s eye is called the station point which generates visual rays (projectors) that define the size of the object. The farther an object is from the picture plane, the smaller it appears to the observer.

For instance, in photography, the camera is placed between the photographer and the object. The camera, where the image is recorded, is the plane of projection or picture plane.

Terms used in perspective drawing

1. Station point (SP):

This is the position of the observer.

2. Eye-level (EL):

This is the position of the eye of the viewer if the object is viewed from below.

3. Picture plane (PP):

This is the vertical transparent plane, placed between the object and station point which the perspective view will be projected.

4. Ground line (GL):

This is the horizontal plane on which the observer stands to intersect the picture plane on the ground line.

5. Horizontal line (HL):

This is the horizontal line on the picture plane which is at the eye level of the observer.

6. Vanishing point (VP):

This is an imaginary point where the line of dimension meets.

Types of perspective drawing

It can be classified according to the number of vanishing points that the drawing has. Therefore, the number of vanishing points depends on the position of the object with respect to the picture plane. So there are two types namely:

1. One-point perspective drawing:

In this type of drawing, the projection lines converge at a particular point known as the vanishing point. e.g. Like the one shown above or the one below:

2. Two-point perspective drawing:

This type contains two vanishing points and the two appear to end at a point in two directions.

In our next class, we will be talking about ORTHOGRAPHIC PROJECTION. We hope you enjoyed the class.
