This repo also generates a webpage at http://sminliwu.github.io/overshot-generator, where you can use the generator in your browser without any other installation or set-up.

This is a P5/Processing sketch that allows someone to quickly make and edit a draft to produce a flowing, curving design using an overshot structure. For a weaving-centered explanation on why this produces a flowing overshot design, read this article by Bonnie Inouye.

There is an interactive tutorial embedded in the generator that guides a user through the basic key commands. In the order that you'd see them, those instructions are:

1. Press '1', '3', or '5' to add a threading block of that width. Press 'r' to reverse pattern direction.

2. Press 't' to switch to editing treadles (or to switch back to threading).

   1. Press a key '1' to '6' to add a treadling block.

   2. Blocks 1-4 are woven as overshot, so tabby rows are automatically inserted before each pattern pick.

3. Press backspace to delete the most recent treadling or threading block.

• +/- : adds/removes one warp (if editing threading) OR one pick/row (if editing treadling) to the draft.
• Shift +/Shift - : zooms in/zooms out.
• p : toggles the highlighted box (threading or treadling) between profile and normal modes.
• Shift p : toggles both threading and treadling between profile and normal modes.
• o : switches the profile mode of treadling.
• You can also click within the threading, tie-up, or treadling to manually edit those boxes. (use at your own risk)

• OvershotCurveGen - Directory for Processing (Java) code for the flowing curves overshot generator.
• index.html - HTML page that runs the P5.js generator.
• overshotCurveGen.js - P5.js code for the flowing curves overshot generator.
• Threading.js - Javascript class for the threading portion of the draft (top left quadrant)
• Treadling.js - Javascript class for the treadling portion of the draft. (bottom right quadrant)

• Sidebar that fully explains the controls like this readme does.
• Exporting the draft as an image.
• Exporting an abbreviated threading draft using my own notation of block lengths with the shaft numbers.
• Further optimizing the P5 version with whatever Javascript offers (suggestions welcome, not a JS expert).
• If you have suggestions for other features/modifications, contact me AND/OR fork the repo to modify the tool!
