BUILDING A DRAWING
·--- ~
We begin by drawing the perceived shape of a vertical plane
that we face.This plane may be the wall of a room. the
facade of a building, or an implied plane defined by two
vertical elements, such as the corners of two buildings.
------·-+--·· We need to establish our eye level relative to the vertical
__--
plane we have chosen. We focus on a specific point and draw
- a horizontal. or horizon line. through that point.
• Notice that horizontal elements situated above our eye level
slope downward toward the horizon. whereas horizontal
elements that are belowrise upward.
• We can establish human figures in the foreground,
middleground, and background to establish avertical scale.
If the vanishing points for a set of horizontal lines lie off the
sheet of the drawing. we can draw the front and rear vertica l
edges of a receding face and judge what proportion of the
vertica l leading edge lies above the horizon line and wh lies
at
below. We can then reproduce the sam proportions for the
e
rear vertical edge.
• W use theestablished points toguide the drawing of the
e
inclined lines in perspective. These receding lines along with
the horizon line then serve as visual guides for any other
lines that converge at the same point.
