Three
point perspective uses three sets of orthogonal
lines and three
vanishing points to draw each object.

Three
Point Perspective is the most complex form of perspective
drawing.
This
technique is most commonly used when drawing buildings viewed
from a low or high eye-level.
A
Low Eye Level
The
low eye level in our illustration above creates the illusion
that the box is towering over us. It now has the scale of
a tall building.
As
the viewer has to tilt their head back to look up, the picture
plane is no longer at right angles to the ground plane.
In
one and two point perspective, the picture plane is fixed
at right angles to the ground plane.
In
three point perspective, the picture plane is set at an
angle.
As
a consequence, the transversal
lines, which were parallel in one and two point perspective,
now appear to recede. They form a third set of orthogonal
lines, which rise from the ground plane and eventually meet
at vanishing point 3, high above the picture plane.
A
High Eye Level
Three
point perspective is also used when drawing an object from
a high eye level as in our illustration below.

It
creates the illusion of looking down from a high viewpoint.
This
drawing process is simply a reversal of the method used
for drawing a box from a low eye level. |
