Wings 3D is a free 3D modeling software, written in Erlang, an open source, functional programming language distributed by Ericsson. 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. Wings 3D offers a wide range of modeling tools, a customizable interface, support for lights and materials, and a built-in AutoUV mapping facility. Though, there is no support in Wings 3D for animation.
Wings 3D is open source and completely free for use in both personal and commercial projects. It is supported by Windows, Mac, and Linux. You can download the latest version of Wings 3D on their official website. This 3D modeling tool is compatible with various file formats.
The key aspects of Wings 3D software are its user-friendly interface and its ease of use. You will get a good preview of these qualities in this Wings 3D tutorial.
