Three-point towers 81 FURTHER ASPECTS OF PERSPECTIVE

This drawing depicts three-point perspective, d
useful for representing steep views looking up
or down tall structures. (Turn the book around
to see a view looking up.) By comparing this

drawing t o Piranesi's example of two-point
perspective on p.75, you will see how, by adding
a third point you can achieve a sense of incline.

Three-point curves

Here, three vanishing points are evenly spaced
along a horizon line. An array of curved lines
(drawn freehand) link the two lateral points.

Iusedthese lines as a guide t o draw the
curvature of boxes and panels flying through
space. Giving curvature, and therefore tension,

tostraightlines can amplify drama in a picture.

Three-point checkered floor

This

bottom floor.Istarted with two parallel lines. I marked the
toplinewith three evenly spaced points and the
line with seven. I then drew three fanned
groups of lines connecting each of the three
points above to the seven points below. Where
thelinescross, they mark the corners of the floor

tiles.Finally,I added horizontal lines t o define the
tiles. Note that altering the distance between the
three dots above will tilt the level of the floor
