Matching
The pairing functions everything else uses, available on their own.
matchNodes()
Pairs two lists of element descriptions (kind, text, box, colour, parent). This is what transitions use.
const { pairs, added, removed, splits, merges } = matchNodes(before, after, { threshold: 0.5 });matchPoints()
Pairs two clouds of points so the total distance travelled is as small as possible. Exact for small clouds; for large ones a fast approximation lands within a few percent of the best.
const { pairs, leaving, arriving } = matchPoints(oldPoints, newPoints, { maxDistance: 80 });
