Image augmentation for machine learning experiments.

The public CGAL repository, see the README below

🌎 Large-scale WebGL-powered Geospatial Data Visualization analysis framework which relies on Mapbox GL or AMap to render basemaps.

The fastest and smallest JavaScript polygon triangulation library for your WebGL apps

🍂🗺️ The most powerful leaflet plugin for drawing and editing geometry layers

A modest library for moving between Well-Known Text (WKT) and various framework geometries

🌏 FreeDraw allows the free-hand drawing of shapes on your Leaflet.js map layer – providing an intuitive and familiar UX for creating geospatial boundaries similar to Zoopla and others. Included out-of-the-box is the concaving of polygons, polygon merging and simplifying, as well as the ability to add edges and modify existing shapes.

Fast, header-only polygon triangulation

Martinez-Rueda polygon clipping algorithm, does boolean operation on polygons (multipolygons, polygons with holes etc): intersection, union, difference, xor

RectLabel - An image annotation tool to label images for bounding box object detection and segmentation.

A library of intersection algorithms covering all SVG shape types

2D Geometry for Unity. Suited for everyday polygon hassle. Polygon clipping, polygon winding direction, polygon area, polygon centroid, centroid of multiple polygons, line intersection, point-line distance, segment intersection, polygon-point containment, polygon triangulation, polygon Voronoi diagram, polygon offset, polygon outline, polygon buffer, polygon union, polygon substraction, polygon boolean operations, and more. It is a polygon fest.

100x Faster Slicing of SCAD Files for 3D Printing

C# port of the famous GLU Tessellator - prebuilt binaries now available in "releases" tab
