3D origami

3D origami is also called Chinese origami. In fact, the so-called 3D origami here is a type of modular origami, but this type is relatively simple. Its basic unit is a non-simple small triangle. There are usually about hundreds of such small triangles, and when inserted one by one, a very beautiful work can be made. The number of small triangles required is related to the complexity of the work and the size of the model. Generally speaking, 250 to 500 units can make a swan or a pineapple. I believe many people are familiar with this paper crafting skill.
