ICP Algorithm for Rhino3D

The JTS Topology Suite is a Java library for creating and manipulating vector geometry.

Digital Geometry Tools and Algorithm Library

The more dimensions, the better the geometry.

Scalable symbolic-numeric set computations in Julia

Computation of Midcurve of Thin Polygons using Neural Networks

This is a short astro-physical program showing how to compute the adhesion model, describing the large-scale structure of the Universe, using regular triangulations in CGAL (www.cgal.org), as well as using the Convex Hull algorithm present in Python's Scipy.

Computational geometry and meshing algorithms in Julia

The public CGAL repository, see the README below

detecting collisions between bodies: Points, Lines, Boxes, Polygons (Concave too), Ellipses and Circles. Also RayCasting. All bodies can have offset, rotation, scale, bounding box padding, can be static (non moving) or be trigger bodies (non colliding).

A Rust implementation of the Polylabel algorithm, with FFI.

Deltares C++library for creating and editing meshes. It supports 1D & 2D unstructured meshes as well as curvilinear meshes.

Polygonal mesh generator

ZSPACE is a simple C++ collection of geometry data-structures & algorithms.

Geometry processing library in pure rust

RBush — a high-performance JavaScript R-tree-based 2D spatial index for points and rectangles

A C++ playground for computational geometry algorithms & plotting.

Boost.Geometry - Generic Geometry Library | Requires C++14 since Boost 1.75

Very fast Python line simplification using either the RDP or Visvalingam-Whyatt algorithm implemented in Rust
