algorithmic modeling for Rhino

Inspiration from work from Petros Vrellis

Images made with script from here
From an image of Danny Santos

With 2000 lines, alpha = 127, image width= 684 * height 551 pixel, 200 pins => 1 hour calculation

Nice!  Pegs and weaving reminds me of the work of Achim Menges:

btw, great script, laurent,  thanks.

a regular portal cnc will do, too. check out this guy.

just wonder, how he seems to be incrementally raising z-level (apart from ramping up on rapid moves) around each nail, depending on the number of previous layers... probably not too difficult to do with his particular spirograph pattern, especially if using grasshopper to generate Gcode, but tracking the number of previous layers for each pin with these vrellis images, good luck.

or lay the thread down at a maximum safe z height each time, and push the artwork down by hand as it goes.

unless the feeding rig is strong and the yarn tension high enough to approach each pin at a max z height and then helix down on its way around the pin to tighten up previous layers. then ramp up for a safe rapid to the next pin.

It is a single path (polyline). You input a list of (pin) points and the script outputs indices of the path. I am sure it is doable with a robot arm.

Is it possible to make the lines into a single path and let the robot arm weave the painting?
