Non-linear Perspective(atmospheric)

• The effect of air and light on how an object is
  perceived by the viewer. The more air between the
  viewer and the object, the more the object seems
  to fade.
• Rendered in 2 dimensions by adjusting the size,
  position, color and value of objects in the
  artwork to mimic the actual effects of air and
  light in life (see handout).

Identifying the non-linear rules in use
Colors are less intense with distance/Values
lighten with distance
Size gets smaller with distance/ Details are lost
over distance
Objects that overlap other objects seem to be
less distant

Linear Perspective

• A system using lines that creates the illusion of
  depth and volume on a flat surface.
• One-point receding objects have one plane facing
  parallel to the viewer
• Two-point receding objects sit on a corner angle
  from the viewer
• Three-point receding objects show extreme height
  or depth

5
Terms

• Horizon line line indicating eye level for the
  viewer
• Vanishing point point to which all lines
  indicating the planes that go away from the
  viewer recede
• Orthagonals (convergence lines) the lines that
  converge at the vanishing point.

Renaissance birthplace of linear perspective in
the Western tradition.
Giovanni Paolo Panini. Interior of St. Peters,
Rome. 1746-54. Oil on canvas. National Gallery of
art, Washington, D.C.

Paolo Ucello Too much of a good thing?
Hes famous among linear perspective buffs for
his exquisitely rendered sketch of a chalice
using mathematical formulas. But
would men, horses, and weapons only fall on
orthagonals in an actual battle?
Battle of San Romano, 1397-1475.
