Besides fixes and general enhancement to existing packages, the following Besides fixes and general enhancement to existing packages, the following
has changed since CGAL 4.12: has changed since CGAL 4.13:
### 3D Periodic Mesh Generation (new package) ### 2D Periodic Hyperbolic Triangulations (new package)
- This package generates 3-dimensional periodic meshes. It computes - This package allows the computation of Delaunay triangulations of
isotropic simplicial meshes for domains described through implicit the Bolza surface. The Bolza surface is the most symmetric
functional boundaries over the flat torus (which can also seen in hyperbolic surface of genus 2. Its fundamental domain is the
the Euclidean space as a periodic cube). The output is a periodic regular hyperbolic octagon with angles π/4 centered at the origin
3D mesh of the domain volume and conformal surface meshes for all of the Poincaré disk. Triangulations of the Bolza surface can be
the boundary and subdividing surfaces. The package is closely seen as triangulations of the hyperbolic plane that are periodic
related to the 3D Mesh Generation package, with similar concepts, in the four directions defined by the sides of this regular
classes, and API. octagon.
### 2D Hyperbolic Triangulations (new package)
- This package allows the computation of Delaunay Triangulations of
sets of points in the Poincaré disk, which is one of the
conformal models for the hyperbolic plane.
### The Heat Method (new package)
- This package provides an algorithm that solves the single- or
multiple-source shortest path problem by returning an
approximation of the geodesic distance for all vertices of a
triangle mesh to the closest vertex in a given set of source
vertices.
### Triangulated Surface Mesh Approximation (new package)
- This package implements the Variational Shape Approximation method
to approximate an input surface triangle mesh by a simpler surface
triangle mesh.
### Classification See https://www.cgal.org/2019/03/04/cgal414-beta1/ for a complete list of
- This package can now handle classification of surface meshes and
clusters, and can compute features in parallel.
