# Bonnie Eisenman on Multiphase Numerical Modeling... for Jigsaw Puzzle Generation

This paper explores expansions on the stylistic variety of handmade and artisanal jigsaw puzzles through the application of techniques from natural simulation. Typical jigsaw puzzle designs reflect the manufacturing constraints of die-cut, mass-production methods, but novel families of puzzle forms can be generated by applying a phase field approach to the simulation of dendritic solidification (http://www.phase-trans.msm.cam.ac.uk/dendrites.html). Existing models of solidification with multiphase methods are extended to satisfy aesthetic and geometric considerations specific to jigsaw puzzle design.

It's a mixture of math, physics, and good old-fashioned puzzling.

NYC Slides @ http://bit.ly/pwl-puzzles
2. ### Hi, I'm Bonnie. • SWE @ Twitter • NYC Resistor

member • @brindelle • blog.bonnieeisenman.com • I like: knitting, languages, lasers, generative art

9. ### Things you can laser • Wood • Plastic (acrylic, Delrin)

• Paper • Leather (sometimes) • Pie

15. ### What makes a good puzzle? • Relative size, shape, and

tiling of pieces • Distinctiveness & "clickiness" of piece boundaries • Novelty of shapes & whimsies • Pretty pictures

of this??

33. ### What makes a good puzzle? • Relative size, shape, and

tiling of pieces • Distinctiveness & "clickiness" of piece boundaries • Novelty of shapes & whimsies

38. ### dart-throwing for blue noise generation → voronoi polygons → sinusoidal

edge perturbation → graph coloring → multiphase dendritic solidification

45. ### Things I learned • Piece boundaries are just one part

of the equation • Seed placement and distribution matters a lot • Math!!!
46. ### Future experiments • Whimsy deformation • Piece collision & interlocking

• Different seed distributions • Other kinds of initial boundaries
