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... -

Open Asset Import Library
The open-asset-importer-library repository
The Open Asset Import Library (short name: Assimp) is a portable Open-Source library to import various well-known 3D model formats in a uniform manner. The most recent version also knows how to export 3d files and is therefore suitable as a general-purpose 3D model converter. See the feature-list. open3mod is a Windows-based model viewer. It loads all file formats that Assimp supports and is perfectly suited to quickly inspect 3d assets. Assimp aims to provide a full asset conversion... -

unwarp
Increase image resolution by eliminating atmospheric distortion
Unwarp is an open-source tool that enhances image resolution by eliminating scintillations caused by atmospheric turbulence and similar distortion phenomena. The software processes a series of images of the same subject, aligning and stacking them using advanced feature selection algorithms and phase correlation approaches. The core technique matches features between images, applies triangulation across the entire frame, and warps each pixel to its optimal position. The resulting aligned... -

headsort
headsort: streaming sort + 2x faster than gnu sort
headsort sorts files by line and fields. Options can pick field order and etc. In general headsort can sort in 1/2 the time sort(1) (mergesort) does in situations involving either pipes or mult column selection; less than 1/2 with both. Best case was about opposite that of sort(1)*. NEW* hsort main algorithm speed improvement (applies to all; 27,29,31). Now faster than sort(1) (in all cases tested). Using triangulation, hsort begins piped sorted output when 1st bin is done... -

Triangula
Generate high-quality triangulated and polygonal art from images
... to the Permissions tab in the executable's properties and tick `Allow executing file as program`. For almost all cases, only changing the number of points and leaving all other options with their default values will generate an optimal result. While all these algorithms are iterative algorithms, the main difference is that in the other algorithms triangles can overlap while Triangula generates a triangulation. -

OpenPose
Real-time multi-person keypoint detection library for body, face, etc.
OpenPose has represented the first real-time multi-person system to jointly detect human body, hand, facial, and foot keypoints (in total 135 keypoints) on single images. It is authored by Ginés Hidalgo, Zhe Cao, Tomas Simon, Shih-En Wei, Yaadhav Raaj, Hanbyul Joo, and Yaser Sheikh. It is maintained by Ginés Hidalgo and Yaadhav Raaj. OpenPose would not be possible without the CMU Panoptic Studio dataset. We would also like to thank all the people who has helped OpenPose in any way. 15, 18 or... -

triangulate
Polygon triangulation library
This is a C++11 library for triangulating simple polygons (i.e. not self-intersecting, no holes) in 2D. It is small and only requires a minimum of memory for triangulation. Memory consumption is in O(log n). Time complexity is between O(n log n) for convex polygons and O(n^3) in the worst case. -

tinyobjloader
Tiny but powerful single file wavefront obj loader
Tiny but powerful single file wavefront obj loader written in C++03. No dependency except for C++ STL. It can parse over 10M polygons with moderate memory and time. tinyobjloader is good for embedding .obj loader to your (global illumination) renderer. We recommend to use master (main) branch. Its v2.0 release candidate. Most features are now nearly robust and stable (The remaining task for release v2.0 is polishing C++ and Python API). -

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... -

connect3d
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... -

XFEM
XFEM implementation in MATLAB
The extended finite element method (XFEM) classified, one of the partition of unity method (PUM), allows discontinuities to be simulated independently of the mesh. This is possible by adding appropriate functions to the FE approximation basis, for example, the Heaviside function. The discontinuities can evolve in time, without a need for a conforming mesh. A MATLAB implementation of the XFEM written by VP Nguyen, is given here. The interaction of cracks and crack-inclusion interaction is... -
