The process of generating an image with thread is an idea of Petros Vrellis. As I've documented here the process is comprised of three steps:
- Image pre-processing (cropping, resizing, etc.)
- Algorithm to place threads
- In my case parsing the result to G-Code for automated fabrication
A set of two example images can be found below. Please refer to my blog for more details.
