Impressive project taken through automated fabrication
From 1 comment
I had the same thought - VERY cool project and fantastic that you took it all the way through the automated fabrication. Impressive already, but I bet you can improve the…

Cool and well executed
From 3 comments
This is very, very cool. Thanks for sharing!
zalq on HNreally nice! in your fitness function - wouldn't you prefer to normalize somehow for the the line's length? i.e. - longer lines (going between two far away pins) will cover more…
rouli on HNThat's awesome, nice work! Personally, can't say I understand image pre-processing well but did you notice that original Petros Vrellis images have deeper black color in some…

Image quality is limited by pin count and optimization approach
From 2 comments
You most definitely could! While experimenting with it it turned out however that the quality of the image is far more sensitive to the number of pins on the loom. And it is this…
theveloped on HNTrue, but an increased number of pins is slower on the plotter and making the scaffolding is also harder. Plus it is easier to rewrap the loom better than to make a finer loom. I…

Requests
Better optimization, such as lookahead or Radon/Hough-based line selection
From 3 comments
Very cool. I wonder if there could be an improvement in image quality if you added some form of lookahead, and chose the path that gives the best results. The branching factor…
snovv_crash on HNI would look at tomographic reconstruction (https://en.wikipedia.org/wiki/Tomographic_reconstruction) algorithms for this for inspiration. This is a very similar problem: what…
Someone on HNAs a physicist my first approach would be using Radon transform [1]. Should be tweaked a little, as overlapping threads are not additive in color (for black threads it's…

Linear color space or log-brightness transform for more accurate thread coverage
From 1 comment
A couple thoughts: Unless your image library is way fancier than I imagine, you would get a much less biased result if you convert to a linear color space. This code: ``` #…

Questions
Was the loom made or bought, and how was it built?
From 1 comment
Dis you make the 200 pin loom or buy it? I can't seem to find such a product online.

Very interesting! The inspiration behind this post, artist Petros Vrellis, uses computer algorithm too: http://artof01.com/vrellis/works/knit.html
