Jigsaw generator

SVG puzzle drawing for laser cutters, print, etc.

Thanks for helping me out and testing this. It will be live on larsenwork.com once I'm done tweaking it. Until then it might change behaviour.

How to use it

• The generator is deterministic: the same inputs will always generate the same puzzle shape. Input values are stored in the file name of the saved svg.
• The variation inputs control how distorted/unique each piece is.
• Change the seed value if you want two sets that are otherwise identical apart from how tab direction and randomness is applied.
• Download the svg and either print it or open it with your laser cutter software.

The science

7 predefined points make up one side of a puzzle piece. We draw a curvy line through these points with Catmull-Rom interpolation courtesy of d3-shape.

A pseudo random number generator (PRNG) is used to add/subtract a random value from the each coordinate prior to drawing the curve. It's also used to determine the direction of the tabs.
