Wings 3D

Wings 3D is an advanced subdivision modeler that is both powerful and easy to use.

Originally inspired by Nendo and Mirai from Izware, Wings 3D has been developed since 2001, when Björn Gustavsson (bjorng) and Dan Gudmundsson (dgud) first started the project. Richard Jones (optigon) maintained Wings and coded many new features between 2006 and 2012. Wings 3D is currently maintained by Dan with the help of the great community.

Wings 3D offers a wide range of modeling tools, a customizable interface, support for lights and materials, and a built-in AutoUV mapping facility.
There is no support in Wings for animation.

Erlang

Wings 3D is written in Erlang, an open source, functional programming language distributed by Ericsson.

Winged Edge Data Structure

Wings 3D gets its name from the Winged Edge Data Structure (WEDS). This is the data structure used to store the adjacency relationships between edges, faces, and vertices in a Wings 3D model.

Open Source

Wings 3D is open source and completely free for use in both personal and commercial projects.
