Perspective Drawings Definitions

• Horizontal line
• Vertical line
• Converging line (Orthagonals)
• Vanishing point
• Horizon

3
Horizontal Line

• Lines that run across the page always parallel to
  the bottom of the page

4
Vertical Line

• Lines that run from top to bottom of the page
  always parallel to the side of the page

5
Converging Line / Orthagonal

• Lines that converge at the vanishing point.
• These are any lines that are moving away from the
  viewer at an angle parallel to the direction that
  the viewer is looking.
• In the case of a highway these lines would be the
  edges of the highway as they move away from you
  forward into the distance.

6
Vanishing Point

• The point to which all lines which are parallel
  to the viewer recede.
• Think of the last time you were looking down a
  long stretch of straight highway. The edges of
  that highway appear to move at an angle upward
  until they meet the horizon.
• In one point perspective all verticals and
  horizontals stay the same and only lines that are
  moving away from or toward the viewer seem to
  recede on the horizon at the vanishing point.

7
Horizon

• Horizon - is always at eye level. Picture
  yourself at the seashore and looking out at the
  ocean you notice that the water meets the sky at
  your eye level. This never changes.
• You may be in an airplane 1000 feet up or you may
  be lying down on the beach and the ocean level
  drops with you.
• Think of it as an invisible plane that cuts
  through everything, that always exists at eye
  level.

Perspective Drawings

• One-point
• Two-point
• Internal
• External

9
One-Point

• All converging lines vanish to one point
• Horizontal and vertical lines do not change

10
Two-Point

• All converging lines vanish to 2 points on the
  horizon
• Always start with drawing a vertical edge
• There are no horizontal lines in 2-point
  perspective
