Rhinoceros Origami

[Emmanuel Des Meaux]

Ive been into origami for quite some time now, and I've been teaching it here on Origami.me for over 14 years. My other hobbies include martial arts, travel, video games and Go. I'm also the author of Everyone Can Learn Origami. You should definitely check it out!

Traditionally, people fold origami by following folding diagrams, which list out the steps in sequential order. However, at more advanced levels, you can fold origami with nothing but a crease pattern, also called a CP. A CP shows where all the essential creases will lie, if the paper were fully unfolded. CPs provide information in a much more condensed format, and are far easier to create than folding diagrams, so it tends to be a lot easier to find CPs than full folding diagrams.

I love to compare the different approaches on the same subject, so I'm choosing the simplest and the most detailed rhino I could find. For me is almost magical to think that origami can be such different things.

Designing foldable products with rigid folding motion is difficult for designers, architects, and researchers who are not origami experts. Crane is a powerful tool for not only such people but also origami experts [1]. This software focuses on design, rigid folding simulation, form-finding, and fabrication for origami. Because Crane Solver is a hard constraint solver, it can precisely simulate a rigid folding motion and form-finding with geometrical constraints like Freeform Origami [2][3].

How to use Crane:

1. Create an initial origami crease pattern using tessellation components or manual drawing.

2. Simulate the rigid folding motion using the crane solver.

3. Find the form that satisfies given geometrical constraints using the crane solver and constraint components.

4. Generate cutting lines or solids for a CNC, a laser cutter, or a 3d printer using fabrication components.

Troubleshooting:

If you have a missing components problem, please check the below.

1. Check whether you unblocked the "crane10.zip" before unzipping it.

2. Right-click crane10.zip and select "properties", then uncheck the "Unblock" check box.

3. Then you can reinstall Crane and it will work well.

We would like to express our very great appreciation to Tomohiro Tachi for teaching the principle of rigid-folding/form-finding simulations and providing machine tools.

We would like to thank Yuta Shimoda for providing the design of the foldable chair.

We would like to thank A-POC ABLE ISSEY MIYAKE for the great collaboration in applying a computational design to "Steam Stretch" to make almost any 3d shape from a piece of cloth [4]. These results were exhibited at the 2023 Milan Design Week.

The Blank Park Zoo doesn't have elephants, but it does have two black rhinos, which are poached in the wild for their horns, said Ryan Bickel, a zoo spokesman. Rhinos' horns have keratin, which is used for medicinal purposes in Southeast Asia, he said.

Kathy Krogmeier, a zoo volunteer, educated kids and parents on the "critically endangered" black rhino while they folded the simple paper elephant. There are about 5,500 black rhinos living in the wild today, down from 65,000 in 1970, she said. Ayana and Kiano, who are both 5 years old, live at Blank Park Zoo. Ayana is pregnant and due in late fall.

It is against federal law to trade the animal material across state lines, and in June the United States Fish and Wildlife Service announced a ban on commercial trade of African elephant ivory. A northern Iowa taxidermist was sentenced to 27 months in prison last year for purchasing and transporting black rhinoceros horns from Oregon to Iowa.
