Wings 3D is a free and open-source subdivision modeller 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 most platforms, including Windows, Linux and Mac OS X, using the Erlang environment.

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.
