Hex Pleating and Pythagorean Stretches

Rdude · Post by **Rdude** » February 8th, 2010, 3:08 am

I know that there is a topic on Hex pleating but I do not recall it being helpful in answering my questions. I have seen several origami designs that make use of Hex pleating, and have heard of Pythagorean stretches being used as a molecule of sorts in box pleating to squeeze more length out of a flap. I am interested in learning more about these techniques, but am unsure where to even start looking for information, so my question is, does anyone know a good source of this information, or any articles that might prove to be useful for me to read?

Thanks in advance,

Andrew

There should be a booklet published by JOAS and written by Robert Lang on exactly these topics that should be available anytime very soon. I've been expecting to see it on their website for a little while now, but it should be coming soon.

Great! I'm really looking forward to this book now!

Thanks for the info!

Like boxpleating, hex pleating is basically an application of circle-river packing restricted to a hexagonal grid. It works much the same way-- you come up with a stick figure, turn it into a polygon packing and use that to draw a CP. The only difference is that you're on a different symmetry system, so some structures are easier than they are on a square grid, for example a base with six equal flaps.

Robert Lang said during a talk that the width of the flaps is thinner when using hex pleating, which is good for making skinny legs.
