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. -

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.

headsort
headsort: streaming sort + 2x faster than gnu sort
...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. This means it has new applications in distributed computing and in some cases makes dc un-necessary. (gnu sort must finish all bins) Well compatible with gnu sort (not perfect). other algorthms featured if menu used: bubble, selection, insertion, shell, distributive counting, straight radix, radix exchange, quick, merge. ... -

OpenMVG
open Multiple View Geometry library. Basis for 3D computer vision
...It provides an end-to-end framework for reconstructing 3D scenes from collections of ordinary images. Its libraries cover image handling, feature description, feature matching, feature tracking, camera models, triangulation, robust estimation, and geometric solvers. Command-line binaries handle individual reconstruction stages that can be combined into complete pipelines. Reconstructed scenes can be exported to other multi-view stereo tools for dense point clouds and textured meshes. The project emphasizes readable, maintainable implementations backed by tests and examples. ... -

Triangle
Convert images to computer generated art using delaunay triangulation
Triangle is a Go image-processing tool that converts ordinary images into low-poly artwork using Delaunay triangulation. The pipeline first blurs the image, converts it to grayscale, and applies Sobel edge detection. Additional filtering selects representative points before the triangulation stage builds the final polygon structure. Users can adjust point density, blur, noise, edge sensitivity, wireframes, stroke width, grayscale output, and background color. -

Triangula
Generate high-quality triangulated and polygonal art from images
...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). -

Starling Extension Graphics
flash.display.Graphics style extension for the Starling Flash GPU
Starling-Extension-Graphics is an extension for the Starling framework (which itself is a GPU-accelerated 2D framework for Flash/AIR via Stage3D). This extension adds graphics primitives (fills, strokes, planes etc.) that mimic flash.display.Graphics-style drawing but implemented in a GPU-friendly manner. It automatically triangulates vector shapes, letting developers use familiar drawing APIs but get performance benefits of GPU rendering via Starling. Starling is an ActionScript 3 library... -

connect3d
Reconstruct Water-Tight Triangulation from Point Cloud
...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 is available as well. -

N-Angulator
N-Dimensional sparse array, editor, and browser in (x)emacs lisp.

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... -
