Delaunator is a fast library for Delaunay triangulation. It takes as input a set of points. The triangulation is represented as compact arrays of integers. It’s less convenient than other representations but is the reason the library is fast. After constructing a delaunay = Delaunator.from(points) object, it will have a triangles array and a halfedges array, both indexed by half-edge id. What’s a half-edge? A triangle edge may be shared with another triangle. Instead of thinking about each edge A↔︎B, we will use two half-edges A→B and B→A. Having two half-edges is the key to everything this library provides. It will also be useful to have some helper functions to go from one half-edge to the next and previous half-edges in the same triangle. We can draw all the triangle edges without constructing the triangles themselves.

A really fast static spatial index for 2D points and rectangles in JavaScript. An efficient implementation of the packed Hilbert R-tree algorithm. Enables fast spatial queries on a very large number of objects (e.g. millions), which is very useful in maps, data visualizations and computational geometry algorithms.

The Javascript Clipper library performs clipping and offsetting for both lines and polygons. All four boolean clipping operations are supported - intersection, union, difference and exclusive-or. Polygons can be of any shape including self-intersecting polygons.

Небольшая и быстрая библиотека написанная на javascript, которая генерирует псевдослучайные числа с практически непредсказуемым разбросом вероятности выпадения для каждого генерируемого числа, а также случайно динамическими границами диапазона псевдослучайной последовательности (для каждого генерируемого числа). Другими словами: эта библиотека ведет себя настолько не предсказуемо, что иногда выдает неопределенное значение (NaN) или бесконечность (Infinity), и почему это происходит не знает даже сам разработчик!
