First, draw a background color on paper, on the ground or on the wall. The background color should be gradually changed, and the range of the background color should be slightly larger than that of the text. Then write on the background color, which is different from the background color. For example, the wall is red, the background color is yellow and the characters are black. The words are half on the yellow background and half on the red wall. The three-dimensional sense of the word comes out.
Second, write on the computer with a pressure-sensitive pen. The principle is the same as above Use software to match various background colors, and the typed words will have a three-dimensional effect.
Third, write raster three-dimensional characters. On the computer, the words are written as raster words, printed and output on paper, and the grating (an organic plate that refracts light) is placed on it, so that the words seen by human eyes through the grating have a three-dimensional effect. It's a real three-dimensional feeling with a deep background. The first two methods create a stronger stereoscopic impression.
