Many of you may know the illustration by Ypey that shows how patterns develop in a twisted rod when slowly removing layers. For years, I have been wondering how to simulate these patterns on a computer. Yesterday, I finally had an insight and was able to produce this in just a few minutes. Here is one picture, I will probably turn this into an illustrative video:

Let me know what you think.

This has been one of my interests for quite some time.

I would love to hear about your process and the software used.

 

I was trying to upload an image but is not working. I'll try later using a smaller file.

It is supposed to be an animated GIF but obviously I couldn't make it work here.

Here is my attempt at visualizing the gradual removal of steel:

 

 

I am using SideFX's Houdini for this.

That's really awesome! Note if only someone (one of us :P) created a program that would create a 3D rendering of what the different layers would look like in any layer count with as many permutations as wanted (twisting, folding, cutting, stacking, rotating, crushing, etc.)

Beautifully done, Niels. Almost looks like an MRI.

As mentioned above, I am using SideFX's Houdini. It's a software often used for visual effects. The apprentice version is free.
