3 -- Expression of three-dimensions using destruction of system

Let's try to generate various three-dimensional effects in a process of modifying and destroying a plane shape which does not have any room for three-dimensional illusions. It is very easy to perform an experiment if we work on an organized object consisting of many shapes placed in a good order. On the other hand, it is very difficult to do so if we work on a circle or a triangle whose insides are uniformly colored.

As an example, parallel lines and a square lattice will be discussed.
 
 

(1) Parallel lines changing in direction

When parallel lines change their direction halfway, a three-dimensional illusion is created with a feeling of unevenness.

The parallel lines sometimes continue to look like parallel lines after bending at a certain point, or they sometimes are converted into curved lines The former has a feeling of hardness, while the latter has an elegant emotion.

Figure 419 below is a face of a human being drown using a computer. The complicated shapes of the face consisting of curved surfaces are expressed softly by delicately changing the direction of the parallel lines.
