Delaunator
Fast JavaScript library for Delaunay triangulation of 2D points
Delaunator is a fast library for Delaunay triangulation. It takes as input a set of points. The triangulation is represented as compact arrays of integers. It’s less convenient than other representations but is the reason the library is fast. After constructing a delaunay = Delaunator.from(points) object, it will have a triangles array and a halfedges array, both indexed by half-edge id. What’s a half-edge? A triangle edge may be shared with another triangle. Instead of thinking about each edge... -

FractalImageCompression
Java Fractal Image Compression based on Delaunay triangulation
Implementation of the algorithm of the paper: "Fractal image compression based on Delaunay triangulation and vector quantization" It is a Fractal compression algorithm, based on relationships between regions of the image (in this case triangles), rather than in explicitly the pixel values themselves.

CFD2D
The incompressible Navier-Stokes equations solver in 2D domains
CFD2D is open source software for Linux for solving the non-dimensionalized incompressible Navier-Stokes equations (NSE) inside an arbitrary two-dimensional domain inscribed in a unit square with Dirichlet and "do-nothing" boundary conditions. The space discretization is based on Finite Element Method (FEM) using an approximately uniform triangular mesh. The two choices of FE spaces are offered, these are of the so called MINI-element and of the Taylor-Hood element. The first element... -

TesselSphere
Spherical subdivision utility for MS Windows and Linux
TesselSphere is an OpenGL spherical subdivision utility for MS Windows and Linux. It currently employs particle and geodesic tesselators. The UI uses QHull morphers that split Delaunay and Voronoi hulls to create new cells in the lattice. Additionally, morphers can target individual cells to split or stellate. TesselSphere can be used to generate vertices for geodesic domes, pollen, radiolaria, viruses and other polyhedra. Comes with full documentation and source. Saves VRML 1.0, POV-Ray inc... -

Reconstruct Water-Tight Triangulation from Point Cloud
This software reconstructs water-tight triangulations from point clouds, interpolating the points. It approximates the triangle mesh which minimizes the sum of all triangles' longest edge. As a result, it can interpolate much more sparse sampling as state-of-the-art algorithms. Run-time is in practice linear to that of the Delaunay triangulation of the points. The software is designed as a command-line tool. It can also be used as a library. A plug-in for the Meshlab geometry software... -
