Hand-made three-dimensional graphics is an art form of collage and folding plane materials to make three-dimensional modeling. It has the characteristics of simple structure and diverse shapes, and the production process is also very interesting. Here are some methods of making manual three-dimensional graphics.

1. solid polygon

The first thing you need to prepare is colored paper, scissors and glue. Choose a piece of paper with bright colors, fold it into a triangle, cut off the extra parts and open it into a square. Then choose an angle on the paper, fold the two vertices in half and yield to a right triangle. Next, we need to connect symmetrical creases according to the moire lines.

Finally, you can get an expanded diagram of a cuboid or cube. Cut the unfolded graphics and collage each plane to get a very vivid three-dimensional polygon.

2. stereoscopic flowers

First of all, you need to prepare colored paper, scissors and glue in different colors such as red, yellow and purple. Cut the colored paper into two heart-shaped patterns, one big and one small, and then fix the big one on a piece of white paper. Then, put the small colored paper on the big pattern, gently press it with your fingers to make it uneven, and then mark the position of petals and leaf edges.

Next, you need to cut and shape each petal and leaf, and then put the bent petals and leaves together with glue until they are combined into a vivid and slightly three-dimensional beautiful flower.

3. Stereo animals

First of all, you need to prepare colored paper, scissors and glue in different colors such as red, yellow and white. Cut the colored paper into two drop-shaped or semi-circular patterns, one large and one small, and then fix the large one on a piece of white paper. Then, the small colored paper is superimposed on the large pattern to depict, marking the characteristics and contours of the animals.

Next, you need to cut each part and put them together one by one with glue until they are combined into a lifelike three-dimensional animal model.

The above three methods are all based on three-dimensional modeling of colored paper. The first method pays more attention to the structure of geometric figures. The second method pays more attention to the light and shadow effect and streamlined aesthetic feeling; The third pays more attention to the completeness of form and the description of details.

No matter which way you choose, the production process can not only improve the craftsmanship, but also cultivate the unique creative concept and aesthetic consciousness in this art form.
