geojson-vt - Slice GeoJSON into vector tiles on the fly in the browser

  •    Javascript

A highly efficient JavaScript library for slicing GeoJSON data into vector tiles on the fly, primarily designed to enable rendering and interacting with large geospatial datasets on the browser side (without a server).Created to power GeoJSON in Mapbox GL JS, but can be useful in other visualization platforms like Leaflet and d3, as well as Node.js server applications.

turf - A modular geospatial engine written in JavaScript

  •    Javascript

Turf is a JavaScript library for spatial analysis. It includes traditional spatial operations, helper functions for creating GeoJSON data, and data classification and statistics tools. Turf can be added to your website as a client-side plugin, or you can run Turf server-side with Node.js (see below).Download the minified file, and include it in a script tag. This will expose a global variable named turf.

pywonderland - A tour in the wonderland of math with Python.

  •    Python

A collection of python scripts for drawing beautiful figures or animating interesting algorithms in mathematics. You can visit the website for this repository to see how to use these scripts and get more information of the math behind them.




FreeCAD - An Open Source parametric 3D CAD modeler

  •    C++

FreeCAD is a general purpose feature-based, parametric 3D modeler for CAD, MCAD, CAx, CAE and PLM, aimed directly at mechanical engineering and product design but also fits a wider range of uses in engineering, such as architecture or other engineering specialties. FreeCAD is based on OpenCASCADE, a powerful geometry kernel, features an Open Inventor-compliant 3D scene representation model provided by the Coin 3D library, and a broad Python API.

jsts - JavaScript Topology Suite

  •    Javascript

JSTS is an ECMAScript library of spatial predicates and functions for processing geometry conforming to the Simple Features Specification for SQL published by the Open Geospatial Consortium. JSTS is also a port of the well established Java library JTS. The primary goal of the project is to provide web mapping applications with a complete library for processing and analyzing simple geometries but JSTS can also be used as a free standing geometry library.

BRL-CAD - Solid Modeling System

  •    Java

BRL-CAD is a powerful cross-platform constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing for rendering amp; geometric analyses, network distributed framebuffer support, image & signal-processing tools.

PolygonDrawingUtil - A compact Android utility for constructing and drawing rounded regular polygons

  •    Java

A compact Android utility for constructing and drawing rounded regular polygons. This video was captured using the sample application in this repository. It provides convenient controls for exploring PolygonDrawingUtil's capabilities.


cgal - The public CGAL repository, see the README below

  •    C++

The Computational Geometry Algorithms Library (CGAL) is a C++ library that aims to provide easy access to efficient and reliable algorithms in computational geometry. The primary vector of distribution of CGAL are sources tarballs, released twice a year, announced on the web site of CGAL. The sources distributed that way can be built using the CGAL installation manual.

delaunay - Fast Delaunay Triangulation in JavaScript.

  •    Javascript

This is just a quick little implementation of Delaunay Triangulation in JavaScript. It was mostly ported from Paul Bourke's C implementation, but I referenced some bits from another JavaScript implementation and rewrote a bunch of things in ways more amenable to fast JavaScript execution. To the extent possible by law, I have waived all copyright and related or neighboring rights to this library.

toxiclibsjs - Toxiclibsjs is a library for computational design tasks with JavaScript

  •    Javascript

Toxiclibs.js is a port of Karsten Schmidt's Toxiclibs for Java and Processing. Toxiclibs.js provides powerful datatypes for the browser and node. It works well for manipulating any DOM element, including Canvas and SVG. The plethora of examples demonstrate its use for geometry and color manipulation as well as physics, automata and more. The examples pair with such fine libraries as: Processing.js, Three.js, D3.js or Raphael.js.

geom - 2D/3D geometry toolkit for Clojure/Clojurescript

  •    Shell

Comprehensive and modular geometry toolkit for Clojure/ClojureScript developed in a literate programming style. Currently BETA quality, largely stable, but pre-release software. The libraries have been used in production for several projects, but further breaking API changes are still forthcoming...

geo - S2 geometry library in Go

  •    Go

This is a library for manipulating geometric shapes. Unlike many geometry libraries, S2 is primarily designed to work with spherical geometry, i.e., shapes drawn on a sphere rather than on a planar 2D map. (In fact, the name S2 is derived from the mathematical notation for the unit sphere.) This makes it especially suitable for working with geographic data.Basic representations of angles, intervals, latitude-longitude points, unit 3D vectors, and conversions among them.

Sophus - C++ implementation of Lie Groups using Eigen.

  •    C++

This is a c++ implementation of Lie groups commonly used for 2d and 3d geometric problems (i.e. for Computer Vision or Robotics applications). Among others, this package includes the special orthogonal groups SO(2) and SO(3) to present rotations in 2d and 3d as well as the special Euclidean group SE(2) and SE(3) to represent rigid body transformations (i.e. rotations and translations) in 2d and 3d. Sophus compiles with clang and gcc on Linux and OS X as well as msvc on Windows. The specific compiler and operating system versions which are supported are the ones which are used in the Continuous Integration (CI): See TravisCI and AppVeyor for details.

verb - Open-source, cross-platform NURBS

  •    Javascript

verb is a library for creating and manipulating NURBS surfaces and curves in many languages including JavaScript. verb provides advanced tools like derivative evaluation, adaptive tessellation, and intersection. Verb provides a concurrent execution runtime via WebWorkers in modern browsers and thread pools on other platforms and is suitable for use in a datacenter or in the browser.

InkKit - Drawing and Geometry made easy on iOS - now in Swift 3.0

  •    Swift

In order to use InkKit in a Swift 3.2/3.0 project, ensure you point to the 2.1.0 tag. In order to use InkKit in a Swift 2.3 project, ensure you point to the swift2.3 branch.

geometry - geometry is a minimal, fully customizable and composable zsh prompt theme

  •    Shell

geometry is a minimalistic, fully customizable zsh prompt theme. geometry starts small, with good defaults, and allows you to customize it at your own will. It can be as simple or complex as you like.
