Licences and source code

This page lists the software this site sends to your browser and the software it runs on its server, with their licences. OpenSCAD and some of the libraries in it are under the GNU GPL or LGPL; their source code is offered here, from the same place as the program, below.

The moss pole

The model, mosspole.scad, and this configurator are by the author of this site. No licence has been chosen for them yet.

OpenSCAD, in your browser

The models are rendered in your browser by OpenSCAD, compiled to WebAssembly (/openscad/openscad.wasm and openscad.js). Browsers without WebAssembly's own exceptions get a second build of the same, which emulates them (/openscad/compat/), and browsers that allow it a third that runs on all cores (/openscad/threads/), with oneTBB. For the first and the third, Boost, GMP, lib3mf and FreeType are built again from the same releases.
