20 September 2006

anyone want to try this out (parquet deformation)? i just stuck this on the net and i need to some willing vict^H^H^H^Hbeta testers to see if it works. [More:]

some background: parquet deformations are tilings that gradually change shape. they were either invented, or at least popularised, by an architect called william huff (the link is a paper by him on folding dodecahedrons) and mentioned by douglas hofstadter (the GEB guy) in a scientific american column (collected here). here are some more examples.

i wrote the program above for someone who wanted to include parquet deformations in some furniture he was making (thought i've not heard from him recently, so i don't know how it worked out). the idea is that you add points, join them up with lines, and then drag the corner points around - the program then interpolates so that the changes made at the corners vary smoothly across the image.

disclaimer: this is a self link, obviously, and i used to post quite a bit on mefi, and sometimes here (a few people will recognise my name, i think, although it was some time ago). i cancelled my mefi account or i'd have posted this to projects; i hope it's ok for me to post this here (i really am looking for feedback/bugs - last night i found one that crashed the damn thing). there's also a shareware version - if anyone from mecha wants to test that one out drop me an email and i'll sign you up for free.
oh god, i'm sorry - everything but the first line should be more inside. i forgot.... :o(

is there any way to edit posts?

Someone will come along and edit it for you.

thanks soemone! (i just looked and i made exactly the same mistake in my last post here. apologies again).

I wondered where you went ... you used to be all over MeFi.

just out of interest, did you cancel your mefi account out of ire with the site or to stop yourself spending time posting there? Do you still read mefi?

iconomy: sweet (thanks)! to make "traditional" parquet deformations, the trick is to use several points in a single (grid) square, connect them up, and then shift them relative to each other (when i wrote the program i never expected it would make stuff looking like your picture - that it can do things like that was a kind of happy accident...).

altolinguistic: both, really (also out of embarassment at losing my temper over stupid things). i do still read askme (and even sometimes email answers to people), but nowhere near as much as i used to.

Andrew, I made a few traditional ones as well, but thought you might get a kick out of the trippy one ;)

if it wasn't for those pesky constructivists we could invent a whole new movement... ;o)

I for one have missed your snarks - esp the anti-american rants...

It worked fine for me and had a better look & feel than usual for a Java app (mostly by virtue of not having any ugly gui components). I was a little vexed by the fact that I couldn't draw a line starting from a corner point but once I figured out that I had to start my lines from hollow circles it was fine.

a bug! thank-you! :o)

(the look + feel is largely down to the wonderful piccolo tookit - one of those pieces of software that makes you think "huh - why doesn't everything work like this?").

nice to see you around, andrew. i always appreciated what you had to say on mefi/acooke. what is the possibility that this thing could output vectors? it would be really cool to bring some of these into Maya, and extrude them... or make particles swarm to them... or any number of other visual tricks... i see that it outputs a CSV in the pay version, but an EPS would be so much cooler. ;)
