LineCircles

A harmonograph that doesn’t get boring

LineCircles was designed to be a solution to one of my biggest problems with harmonographs: you need to watch them draw to appreciate the final product, but watching them draw is kind of boring. I built LineCircles with a mind to have it be interesting to watch, require no user input, and produce attractive images.

I bring LineCircles up on my computer whenever I am doing something that requires my attention, but not my vision – things like telephone calls, listening to music, etc.

LineCircles was originally built with Processing, but from version 1.0 has been built using Unity.

    • Minor tweaks to how patterns are generated

31st October, 2015

Solid upgrade. Added some nice user-customisability, mouse navigation, and the ability to watch a single pattern for ages. (If you keep watching for a very long time, you might start running into performance issues.

  • New Features:
    • Can now navigate around the patterns with the mouse
    • Users can toggle camera effects on/off
    • Users can decide if they want to see lines, fill colours, both or none
  • Changes:
    • Screenshots are now saved to /Screenshots and not /Data
  • Bugfixes:
    • Solved bug that was causing background to be very dark grey rather than black (reducing contrast)
    • Solved issue that was preventing single patterns from being drawn for long periods of time
  • [LineCircles_v1.1.zip – 10.0 MB]
26th October, 2015

First proper build – migrated everything over to Unity. This brings whacktons of new potential, none of which I’m currently tapping. Right now, it’s basically a straight reimplementation. However, this has brought massive performance increases – I could probably run 20 or more LineCircles at once now without my CPU/GPU breaking a sweat.

  • New Features:
    • Tremendous performance increase
    • Image effects!
    • Support for true fullscreen
    • Support for multiple resolutions
  • Changes:
    • Changed screenshot key from Shift+S to F12
    • Forced fade out if user tries to keep a single pattern going for ages – this is due to a limit on generative mesh sizes in Unity, and will be fixed in the next version
  • [LineCircles_v1.0.zip – 10.0 MB]
Version 0.1

11th October, 2015
Initial build. Stable and functional, but limited customisability. Am in the process of rebuilding in Unity to enable far more sophisticated features.

  • Draws randomised, colourful harmonographs forever
  • Can save screenshots
  • Some level of user control (skip to next image, disable/enable auto-skip)
  • [LineCircles_v0.1.zip – 38.2 MB]
