Infer looks at the features that border the current one and the figures currently assigned to those features, and tries to extend the lines from the neighbouring figures into into the feature to create a plausible motif. The result is often very natural and similar to traditional designs. In the future, I will add controls to actually construct and edit a map by hand. A discussion on the geometry of these motifs can be found in the Bridges conference preprint . The drop-down chooser on the left lets you choose between stars, rosettes and extended rosettes.
D controls how tight the points of the stars are.
The higher the value of D, the pointer the star. S controls how many segments to draw along each arm of the star. A star with a low value of S is just an outline. Higher values of S add more complex shapes in the interior of the star. The controls for rosettes are similar to those for stars.
