(ii) KOHSEI (Basic Art & Design) using geometric progressions
In preparing two-dimensional diagrams, the areas
having the relations of the geometric progression is very easily obtained.
When using squares or rectangles are used, the lengths of the vertical
and horizontal sides are successively doubled. If the are of the screen
is fixed, the lengths of the vertical and horizontal sides are successively
halved. The works of Figures 245 and 246 are created using these methods.
Shown in Figure 249 is the work in which the
interval of perpendicular lines varies as a geometric progression, and
the intervals of the horizontal lines varies as a Fibonacci progression.
Geometric progressions are attractive because the
size increases or decreases greatly.
