Convex hull of given 3D points

PHP - A simple, low-memory footprint function to generate all combinations from a multi-dimensionnal array.

A simple header-only, single-file library to handle WGS84 coordinate to Cartesian coordinate transformations for C++.

Fast cartesian product

Intervals coupled with algebra of set to handle adaptive mesh refinement and operators on it.

A .NET library that provides strongly-typed implementations of multiple coordinate systems, including rectangular, polar, spherical, and geodetic.

Quadtree Adaptive Mesh Refinement

𝜟𝜱✴︎ or Delta Phi Star is a variant method of determining lightness contrast, and a sibling of APCA and SACAM. It is a simplified version using easily invertible standardized maths, however it lacks some useful properties such as polarity sensitivity. In fact, it is intended for applications where a "general" simplifed perceptual contrast is des…

Python package that converts between polar and cartesian domain (in images too).

2D Cartesian Quadtree Adaptive Mesh Refinement (AMR) for multiphase Five Equations Model

Wangsamas firmware can be used for cartesian, delta and SCARA 3d printers and can be modified for plotter, CNC and laser.
