Level shifters

Anyone who has ever tried to design box pleated origami models knows that those models have rather narrow flaps. This feature doesn't have to be a problem, quite a contrary, it can even be an asset. But when wider flaps are needed, gadgets known as level shifters have to be used. Level shifters, in their essence, allow us…

Origami design process – Part 2

This blog post is intended to be a sequel to the Origami design process (introduction) blog post. But my true intention was to make a blog post that would serve as a comprehensive guide on the origami design process. You see, I have already written numerous posts on the topics concerning various details important to the process itself.…

Uniaxial base

What is a uniaxial base? Every origami model, no matter how complex, has a base in its core. Those bases can vary in their complexity, from simple traditional origami bases to complex custom made bases that can be seen today.  Nevertheless, one class of origami bases stand out: a uniaxial base. A uniaxial base is a class of…

Crease pattern

Nowadays, the vast majority of origami instructions are available only in the form of a crease pattern. Diagrams have become increasingly rare, even though they still can be found in magazines like Tanteidan or Origami books. But since the production of new models is so immense in most cases only what is available are crease patterns.  This is…

How to Collapse Box Pleated Crease Pattern?

Introduction One of the most stated questions on the WEB regarding Origami is: How to collapse a crease pattern based on a box pleating method. Surprisingly the answer is very simple. But before I answer this question, I would like to talk about the reasons why crease patterns are used in the first place. The reason is obvious,…

Pythagorean stretch

Pythagorean stretch Introduction Origami models based on a box pleating method are on average smaller compared to the similar models based on a circle packing method. In extreme cases, the difference could be almost 40%. Therefore, we can say that models based on a box pleating technique are less optimal. Nevertheless, problems can be, to some extent, solved…

Axial creases

Axial crease is one of the three basic origami creases. By definition Axial creases are creases that run in the direction that is perpendicular to the polygon’s hinge creases. Simplest form of a axial creases In most basic form, meaning in the models that do not use more advanced origami techniques such as level shifters or Pythagorean stretch,…

Hinge crease

A hinge crease serves two purposes. By definition, a Hinge crease is a line that defines polygons by the mere fact it surrounds it. Also, a hinge crease is a line around which a flap can rotate. Hence the name. It looks similar to a door hinge. Figure 1 In figure 1 we can see the same hinge…
