Qhull computes the convex hull, Delaunay triangulation, Voronoi diagram, halfspace intersection about a point, furthest-site Delaunay triangulation, and furthest-site Voronoi diagram. The source code runs in 2-d, 3-d, 4-d, and higher dimensions. Qhull implements the Quickhull algorithm for computing the convex hull. It handles roundoff errors from floating point arithmetic. It computes volumes, su
TetGen ist ein Programm zum Erzeugen von tetraedrischen Netzen aus beliebigen 3D-Polyeder-Domänen. TetGen erzeugt exakt eingeschränkte Delaunay-Tetrahedralisierungen, grenzkonforme Delaunay-Netze und Voronoi-Partitionen. TetGen bietet verschiedene Funktionen, um qualitativ hochwertige und adaptive tetraedrische Netze zu erzeugen, die für numerische Methoden wie Finite-Elemente- oder Finite-Volumen
Faculty Innovation: Mathematician Bridges Disciplines to Understand Modeling Limitations What began with a focus on weather forecasting has evolved toward addressing errors in scientific modeling. In the collaborative environment of the Penn State Institute for Computational and Data Sciences, John Harlim combines applied mathematics and data science to develop methods for more-accurate scientific
Voronoi Treemaps Michael Balzer Oliver Deussen Department of Computer and Information Science University of Konstanz, Germany ABSTRACT Treemaps are a well-known method for the visualization of at- tributed hierarchical data. Previously proposed Treemap layout algorithms are limited to rectangular shapes, which causes prob- lems with the aspect ratio of the rectangles as well as with identify- ing
