Perspective Practices, Continued
Dividing lines
When the problem involves finding equal division points of a plane in
or receding
perspective and the placement of these points is known, the problem can be
area into parts
solved as shown in figure 5-23. Since the points are parallel on the object,
in perspective
(Continued)
they have the same vanishing point.
To find incrementally placed horizontal points in perspective, use this table:
Step
Action
1
Locate a horizon line, ground line, and station point.
2
Place a vanishing point and draw a visual ray from the SP to the
VP.
3
At the intersection of A and GL, measure and center the width of
the first horizontal element.
4
Draw lines from each end of the first horizontal element to the VP.
5
Measure incrementally spaced horizontal elements along A to the
intersection of HL.
6
Darken the outlines.
Figure 5-23 shows equally spaced horizontal points.
