Curves and
circles in
perspective
(Continued)
Drawing curves and circles in two-point perspective is similar to drawing in
one-point perspective except for the additional vanishing point.
Figure
shows the circle in two-point perspective.

perspective.
Dividing lines
Sometimes you need to divide a line or area into a number of parts. The key
or receding
to most division of space problems in perspective is the vertical or horizontal
area into parts
in perspective
line parallel to the picture plane.
To divide a receding plane into equal areas, use this table:
Step
Action
1
Divide the left vertical (AO) into equal parts with a ruler or scale.
2
From these points, draw lines to the vanishing point (figure 5-21,
view A).
3
Draw a diagonal from point A to point (figure 5-21, view B).
4
Where the diagonal and receding lines intersect, draw vertical lines.
This divides the receding plane into equal units.
