One-point perspective

Stand in the middle of a straight road and the sides seem to meet in the distance. Perspective drawing uses this to make flat paper look deep.

Key words

Linear perspective is a system for drawing objects so they look 3D and get smaller as they go into the distance.
The horizon line is a horizontal line at the viewer's eye level.
The vanishing point (VP) is a point on the horizon line where lines going away from you seem to meet.
Lines that go away from you and meet at the VP are called orthogonals (or converging lines).

Drawing a box in one-point perspective

1. Draw a horizon line and mark one vanishing point on it.
2. Draw a square or rectangle: this is the front face, facing you.
3. Draw light lines from each corner of the square to the vanishing point.
4. Decide how deep the box is and draw the back edges: horizontal lines stay horizontal and vertical lines stay vertical.
5. Rub out the guidelines you do not need.
One-point perspective works well for roads, railway lines, corridors and rooms seen straight on.

Viewpoint and history

If an object is drawn below the horizon line you see its top (a bird's-eye view). If it is above the horizon line you see its underside (a worm's-eye view).
In Florence in the early 1400s, the architect Filippo Brunelleschi showed how linear perspective works. In 1435 Leon Battista Alberti described it for painters in his book On Painting.
Perspective became one of the great tools of the Renaissance.
Worked example

You draw a box well below the horizon line in one-point perspective. Will you see the top or the bottom of the box? Why?

  1. The horizon line is at your eye level.
  2. An object below your eye level is lower than your eyes, so you look down on it.
  3. Looking down, you see its top surface.

Answer: The top, because the box is below eye level, so you are looking down on it (a bird's-eye view).

Key idea

In one-point perspective, lines going away from you meet at a single vanishing point on the horizon line (eye level). Horizontal lines stay horizontal and verticals stay vertical. Objects below the horizon show their top.

Key words
Vanishing point
A point on the horizon line where receding parallel lines appear to meet.
Horizon line
In perspective drawing, a horizontal line at the viewer's eye level.
Linear perspective
A system of drawing in which parallel lines going away from the viewer meet at vanishing points, creating depth.
