(2) Three-dimensional effect by texture and gradual change of brightness

The thickness of lines used in Figure 387 is fixed, and the three-dimensional effect is expressed using changes in the spacing between the lines. On the other hand, the cubic effect can be also expressed by simply modifying the thickness (or size of points) with the same spacing (distance). The examples below show expressing three-dimensional illusions such as depth or distance by modifying the size of points drawn periodically or the thickness of lines (Figs. 413, 414)

The method of gradual "change" (gradation) was used here to express variation, which is a technique on change in brightness which is similar to the shading described in the previous page. The only difference in these two is texture. 

(3) Three-dimensional effect using colored surfaces.

Warm colors such as orange makes a shape move forward, and cold colors such as blue make it move backwards. If colored surfaces are well organized using these characteristics of colors, feelings of roughness and distance can be expressed. The work of J. Albers, "Poem in Praise of Squares" is famous (Fig. 415). An example introduced in the color illustration 21 is also interesting.

This is a work on a New Year's card, and the orange-colored letters appear to be located in the foreground, while the upper part drawn using orange looks to be located behind the red window. It looks as though the red shape rises from the whole of the screen. Then, once you recognize that the red color is rising, the orange-colored letters in the lower part appear behind along with the orange- colored letters in the upper part.
