The CGAL Open Source Project is pleased to announce the release 6.1 of CGAL, the Computational Geometry Algorithms Library. 3D constrained triangulations, faster Boolean operations, 3D snap rounding, Fréchet distance computation, and much more! Changelog:cgal.org/2025/10/01/cga…
My latest creation with Geotoy, built using the alpha wrap function from the CGAL library I've been getting a ton of value out of this; it's really useful for creating organic-looking structures You can see it in 3D here: 3d.ameo.design/geotoy/edit/62 (takes ~30 seconds to run)
Later today, CGAL will be presented at the seminar "Geometry & Visualization" @FU_Berlin Unusually, focus will be on organizational aspects of the open source project: license choice, infrastructure, sustaining a long-term project, ... mi.fu-berlin.de/en/math/groups… Slides to follow!
Chopping with CGAL is 10 times faster in our upcoming release, CGAL 6.1. Re-implemented from scratch, clipping/splitting now supports non-triangular faces and can handle self-intersecting inputs. More on the blog entry: cgal.org/2025/06/06/new…
The beta release for the next version of CGAL (6.1) is now available! New: - 3D contrained triangulations - Isosurfacing methods - Robust and fast self-intersection removal - 10x faster plane clipping - Frechet distance - ... Full changelog and download: cgal.org/2025/07/07/cga…
New in CGAL: Robust and fast self-intersection removal in triangle meshes! Combining Boolean operations and snap rounding, we remove all self-intersections consistently, for example over all of Thingi10k. Work to be presented at SGP this week. More: cgal.org/2025/06/13/aut…
From time to time, users allow us to tell us how they use CGAL. To learn why recent speed improvements for our Boolean operations are crucial for De Beers Group and Tiffany & Co., check the gallery at cgal.org and read the press release cgal.org/news/2025/04/0…

New in CGAL: 3D Mesh Generation receives another batch of improvements with 6.0 - Recovery of sharp features in labeled images - Weighted labeled images now supported - Improved mesh quality near sharp features for all domain types Blog entry: cgal.org/2024/12/01/mes…
The CGAL Open Source Project is pleased to announce the release 6.0 of CGAL, the Computational Geometry Algorithms Library. Four new packages, 2D AABB Tree, autorefinement of triangle soups, tetrahedral remeshing with sizing fields, and more. Changelog: cgal.org/2024/09/27/cga…
The beta release for the next version of CGAL (6.0) is now available! C++17; four new packages (kinetic surface reconstruction, polygon repair, ...); Boolean operations for polygon soups; sizing fields added to tetrahedral remeshing; and much more! cgal.org/2024/06/21/cga…
Two new packages join CGAL: Kinetic Partitioning and Kinetic Shape Reconstruction. These enable producing watertight, piece-wise planar surfaces from point clouds. Already in master, and released with CGAL 6.0 (beta soon!). Details at cgal.org/2024/05/29/Kin…
