Happy to share the poster on mesh generation with CGAL that we presented last week at IMR26.
It gives a comprehensive overview of the existing tools for 2D, surface, and 3D meshing in CGAL, as well as a glimpse into some on-going developments!
The CGAL project has been accepted as a mentoring organization for the 2026 Google Summer of Code:

New in CGAL: Remeshing of planar patches.
Using this new function, you can remesh models to use as few elements as possible, with control over the geometric error.
Planarity detection is customizable: Region Growing, RANSAC Shape Detection, ...

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.

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 in Bilbao this week.

Input (left); remeshing with a budget of 50k vertices: isotropic (middle) and curvature adapted (right).
Multiple energies are available, for example to produce meshes that are uniform, or curvature adapted.
Documentation: doc.cgal.org/6.1/Polygon_...
Input (left); remeshing without (middle) and with (right) QEM-based placement optimization.
New in CGAL: A new method for surface remeshing, with sharp feature preservation.
"ACVD Remeshing" is based on publications of Valette et al., and uses clusters of vertices, which are grown to minimize a particular energy until convergence.

A binary version of Kitware's VESPA Plugin for Paraview is now available!
This plugin brings some CGAL mesh processing components to VTK and ParaView through a transparent wrapping.
Let us know if there are CGAL components you'd like to see in VESPA!
