CGAL Classification Package Given a point cloud and a user-defined set of classes (e.g. vegetation, ground, roofs, etc.), the algorithm classifies the points by computing a set of geometric attributes and minimizing a globally regularized…
Intergraph’s LPS, a complete suite of photogrammetric production tools, uses the CGAL 2D Delaunay triangulation to perform terrain segmentation, building footprint delineation, and terrain classification on LiDAR point clouds.
Based on weighted graphs representing transport connections, and the CGAL 2D Alpha Shapes the geographical information system IVU.locate* allows to compute catchment areas and hence to identify the optimum location for stores and its customers.
The CGAL 2D Straight Skeleton is used for modeling roofs in the Esri CityEngine, a software product for the efficient creation of 3D cities and buildings. Straight skeletons are further used for computing offset polygons…
Acute3D develops software that allows to build real-3D, high resolution models from simple photographs. They use the CGAL 3D Delaunay triangulation and the AABB Tree, a data structure that allows to perform efficient intersection and…
