Amazing, the mathematics behind origami is so amazing, and Su's origami algorithm has also been seen. The above three articles have introduced the relationship between origami and origami mathematics from different angles, so I won't repeat them here. To answer this question, we need to clarify two concepts: my definition of modern origami is that it refers to the visual static spatial image created by folding a single piece of paper material by hand. In the definition of art, it is clear that "single sheet of paper" (whether "tin foil" is "paper" is not discussed for the time being ...), that is to say, all the modeling details are completed through the reasonable distribution of this single sheet of paper, and "hand folding" restricts the use of other auxiliary tools (including scissors and glue) to put origami into plastic arts, which is of course a visual art appreciated by eyes. Also, after the work is formed, it is no longer a plane thing, but a three-dimensional space. In this definition, there is no clear restriction on the shape of the paper used in the work, and the subdivision here can be understood as different genres. I'm sleepy and incoherent. 2. Shenma is the process of origami creation. My definition of modern origami creation process is: based on geometry and mathematics, considering and dealing with the proportion, structure, color, shape and texture of works is a comprehensive creation process of manual technology and origami art. The theoretical basis mentioned here is easy to understand after reading those three articles (angular bisector, midline, symmetry, equal division, etc.). There are many factors to consider when creating origami works, from the material of paper to the proportion of paper distribution to the mastery of folding technology and skills, as well as the shaping and finalization of the works. So good origami works are not only vivid in shape, but also ingenious in structure. There are poems to prove it: ah ~ ~ ~ ~ origami is architecture, and you appreciate not only the shape but also the structure; Ah ~ ~ ~ ~ ~ origami is a poem with rules to follow, but it is also creative! Well, this is not a poem, and I wrote this poem ~ ~ ~ ~ In short, origami is the combination of technology and art, and the unity of experience and aesthetics. Through origami, you can see science from an artistic point of view and appreciate art from a scientific point of view. That's it ~ ~ ~ ~ Wait a minute, there seems to be no answer "Ah ~ ~ ~ ~ ~". Actually, carpenters who can't count can also build a diaojiao building that conforms to the engineering principle, but high flyers, who graduated from architecture department, may also design the building as the "Leaning Tower of Pisa". There is also that popular science writers are not necessarily scientists.
