CGAL in QGIS #25034

Closed qgib closed 4 years ago

Author Name: Bernardo Chrispim Baron (Bernardo Chrispim Baron) Original Redmine Issue: 17135

Redmine category:c++_plugins

The "Computational Geometry Algorithms Library (CGAL)":https://www.cgal.org provides some complex geometric computations, many of which are not included in any of QGIS' current toolboxes despite being quite useful for geographic analysis (e.g. "triangulations, voronoi diagrams, boolean operations, point set processing, arrangements of curves, surface and volume mesh generation, geometry processing, alpha shapes, convex hull algorithms, shape analysis, AABB and KD trees"). It is "licensed under GPL and LGPL":https://www.cgal.org/license.html and written in C++ with python bindings, so I imagine its packages would be relatively easy to implement in QGIS as a plugin or toolbox.
