More Single Line Art

I am a better line processor than any algorithm we currently have access to. Behold what I turned into a SINGLE LINE by hand:

Look upon my works, ye mighty, and despair!
Look upon my works, ye mighty, and despair!

Many people think we’re using Mathematica to do the drawings of our Quilt Money. We’re not! I am drawing all this stuff by hand. Theo uses Mathematica to route my drawings that contain T-intersections, but I’m learning to make my drawings single lines without T-intersections by hand, because they route much better that way. Everything below was drawn by me, by hand:

$100_new_19_all

Only a few bits (the seals and part of the border) need to be routed in Mathematica. Everything else I drew as single paths. Which is quite a brain-hurter, lemme tell ya. Here’s a screen capture of me working on this same project last week:

I could do this much more efficiently now, using what I’ve learned since then. Which is good, because the better I get at this, the more I can help someone else create algorithms to automate this kind of work.

And yes, at some point we hope to offer an affordable $100 Quilt. But first I have to get the design right, and then our potential partner has to be able actually produce it without losing money. We’re working on it.

Our quilted money is one of the few things I don’t share source (in this case, vector) files for, because currency isn’t exactly like other culture, as I explain here.

The holy grail of quilting design


grail1

Single-line art is the holy grail of quilting design: the sewing machine head can stitch the entire design without starting, stopping, or breaking thread. To illustrate this for an upcoming talk I drew a holy grail as a single-line drawing. I did this by hand in Flash, and made this simulation of a simulator by deleting line segments one at a time.

I would love a program that intelligently automatically converts my line art into single-line art. Theo made something like that already, which preserves all the line segments and relies on back-tracking. But I’d also like something that replicates what I did here by hand: removing and adding small line segments so no back-tracking is needed. It would need to analyze which smaller line segments could be sacrificed, and which segments could be doubled (parallel lines can be easily added to a design like this).

You need single line art for automated quilting, and that’s what we do. But getting from regular line art to single-line art is currently no small task, for humans or computers.

Water Wheel

Back on the Quiltimation front, I was wondering if I could arrange animated frames on a quilt in a mandala/medallion pattern, rather than left-to-right cells. This would essentially be a quilted phenakistoscope, with the animation emerging as the whole thing is rotated (we’d keep the camera and lights stable, and rotate the quilt).

The saturated colors here would be lost, although I could use a few colors of thread. The elements are early Leviathan designs, and Water from Chad Gadya which is still in (very slow) progress.
