Wings 3D

Wings 3D is a free and open-source subdivision modeler inspired by Nendo and Mirai from Izware. Wings 3D is named after the winged-edge data structure it uses internally to store coordinate and adjacency data, and is commonly referred to by its users simply as Wings.

Wings 3D is available for Windows, Linux, and Mac OS X, using the Erlang environment.

Overview
Wings 3D can be used to model and texture low to mid-range polygon models. Wings does not support animations and has only basic OpenGL rendering facilities, although it can export to external rendering software such as POV-Ray and YafRay. Wings is often used in combination with other software, whereby models made in Wings are exported to applications more specialized in rendering and animation such as Blender.

Interface
Wings 3D uses context-sensitive menus as opposed to a highly graphical, icon-oriented interface. Modeling is done using the mouse and keyboard to select and modify different aspects of a model's geometry in four different selection modes: Vertex, Edge, Face and Body. Because of Wings's context-sensitive design, each selection mode has its own set of mesh tools. Many of these tools offer both basic and advanced uses, allowing users to specify vectors and points to change how a tool will affect their model. Wings also allows users to add textures and materials to models, and has built-in AutoUV mapping facilities.
