Learn about the features, capabilities, and latest news of CGAL, and explore the dual license options.

The Git repository of CGAL has a different layout from release tarballs. It contains a CMakeLists.txt file that serves as anchor for configuring and building programs, and a set of subfolders, so called packages.Most packages implement a data structure or an algorithm for CGAL (e.g., Convex_hull_2, or Triangulation_3); however some packages serve special needs:

Using CGAL on Windows (with Visual C++) CGAL 5.6.1 is supported for the following MS Visual C++ compilers: 14.0, 15.9, 16.0, 17.0 (Visual Studio 2015, 2017, 2019, and 2022). CGAL is a library that has mandatory dependencies that must be first installed: Boost and GNU Multiple Precision Arithmetic (GMP) and GNU Multiple Precision Floating-Point ...

The Computational Geometry Algorithms Library (CGAL) is an open source software library of computational geometry algorithms.While primarily written in C++, Scilab bindings and bindings generated with SWIG (supporting Python and Java for now) are also available.. The software is available under dual licensing scheme. When used for other open source software, it is available under open source ...

The CGAL Open Source Project is pleased to announce the release 5.6 of CGAL, the Computational Geometry Algorithms Library. Besides fixes and general enhancement to existing packages, the following has changed since CGAL 5.5:

The CGAL Project. CGAL is a software project that provides easy access to efficient and reliable geometric algorithms in the form of a C++ library. 148 followers.

CGAL, the Computational Geometry Algorithms Library, is written in C++ and consists of three parts. The first part is the kernel, which consists of constant size non-modifiable geometric primitive objects and operations on these objects. The objects are parameterized by a representation class, which specifiesthe coordinate representation and ...

The emerging ligation-free three-dimensional (3D) genome mapping technologies can identify multiplex chromatin interactions with single-molecule precision. These technologies not only offer new insight into high-dimensional chromatin organization and gene regulation, but also introduce new challenge …

A step-by-step guide showing how to install and use CGAL with sources is available in the CGAL Documentation. Through Github Advanced users can clone the current development version of CGAL from GitHub to enjoy early access to new features.

Mesh Processing. Some common geomerty objects are referrenced in a seperate project so they can come under a different license. Work in progress. Only 64 bit windows binarys provided. Examples in Unity can be found in this repository. A page on the Unity forums can be found here. C# wrapper for CGAL. Contribute to Scrawk/CGALDotNet development ...

Then, the bone and implant images were combined into a binarized image with three distinct regions (compact bone, trabecular bone, and stem), and then meshed with 2-mm 4-noded tetrahedral with computational geometry algorithms library (CGAL) to create 3D models of the femurs with stems as described previously .

The Computational Geometry Algorithms Library (CGAL) is an open source software library of computational geometry algorithms. While primarily written inon Debian: CGAL LiveCD – Live CD containing CGAL with all demos compiled. This enables the user to get an impression of CGAL and create CGAL software withoutC++. As of 2016, it uses the Computational Geometry Algorithms Library (CGAL) as its basic CSG engine. Its script syntax reflects a functional programmingwith linking exception. CGAL for versions 3.x.
