origami animations and computer explorations - H A Verrill

The first program linked to here was written in July 2021, based on the svg written for the images on the bottom row. Second program written beginning August 2021. Crease pattern link is older; here for convenience. (links all green)

The rest of this page was written in early 2020. A more recent description of some of the concepts described has been written up here. See also the slides for my Bridges 2021 talk (pdf, created with latex beamer package)

Here are some animations. For this page, I've made mp4 animations by using a screen shot, but the originals, which you can see by clicking on these images, are in either javascript or svg. Click on the links (the green boxes) to see the original files.

The first set are for a crease pattern and corresponding folded origami. The rest only show crease pattern. The third animations in the two columns are actually the same, just different colouring.
The third row shows what I consider the unit of the tessellation/corrugation. You can change the parameters of these. Click on the link to see lots of units together. If you want to actually fold something, you probably want to click on the links on the third row. The fourth row is some folded examples.
Fifth row is links to some svg files animating the actual folding of examples of the middle crease pattern.
