Determines whether the first geometry is completely within the second geometry.

A BVH implementation to speed up raycasting against three.js meshes.

Spectrum 2 UI components in React

Martinez polygon clipping algorithm, does boolean operation on polygons (multipolygons, polygons with holes etc): intersection, union, difference, xor

Removes redundant coordinates from a GeoJSON Geometry.

Resumable streams based on s2.dev, inspired by Vercel's implementation.

Simplify geometry using the Ramer–Douglas–Peucker algorithm.

Geometry operations for X6

Checks if two geometries cross each other.

This library provides classes and functions for the computation of geometric data on the surface of the Earth. Code ported from the Google Maps Javascript API v3

A mesh replacement for `THREE.Line`. Instead of using GL_LINE, it uses a strip of billboarded triangles. This is a fork of [spite/THREE.MeshLine](https://github.com/spite/THREE.MeshLine), previously maintained by studio [Utsuboco](https://github.com/utsub

Pre-built TopoJSON from the U.S. Census Bureau.

A WKT/WKB/EWKT/EWKB/TWKB/GeoJSON parser and serializer

Checks if two geometries have no overlapping areas.

Determine whether each segment of a line is parallel to the correspondent segment of another line.

calculate the physical area of a geojson geometry

Determine whether none of the points common to both geometries intersect the interiors of both geometries.

A JavaScript library of spatial predicates and functions for processing geometry
