Anim8or is a freeware OpenGL-based 3D modeling and animation program by R. Steven Glanville, a software engineer at NVidia. Currently at stable version 1.01.1402, it is a compact program with several tools which would normally be expected in high-end, paid software. To date, every version released has been under 3 MB, despite the fact that it does not make full use of Windows' native interface, carrying some graphical elements of its own. Although few official tutorials have been posted by the author, many other users have posted their own on sites such as YouTube and the anim8or home page. While Anim8or was once comparable to other freeware 3D animation software such as Blender, it has seen less progression in recent years, with Blender now being more capable than before. Development On July 20, 1999, a message was posted to the newsgroup comp.graphics.packages.3dstudio, introducing the first version of Anim8or to the public. In its first week, the original version was downloaded almost 100 times. The next version, 0.2, was released on September 6, 1999, containing bug fixes and the ability to save images as JPEG files. In the past few years, newer versions have been released, introducing features such as undo and redo commands, keyboard shortcuts, an improved renderer and morph targets. With each new version, the popularity of Anim8or has grown. It has been featured in several magazines including 3D User, Freelog, c't and the Lockergnome newsletter. Anim8or's latest stable version, 1.0, was released to the public on May 29, 2017 and includes an updated user interface, more modelling and animation tools, and STL support for 3D printing. Anim8or's mascot is a simple red robin, aptly named as Robin, that most users learn to model and animate in Anim8or's "A Simple Walk Tutorial". Users are often also very familiar with the eggplant, a model first designed by Steven to demonstrate 3D printers at SIGGRAPH. It is likely the first model most Anim8or modellers have ever created, as it is taught in the introductory tutorial to demonstrate the basics of the modeler and the tools available. Layout Anim8or's interface is separated into four sections, each with its own tool set: Object editor - individual objects are stored and edited within the object editor. Objects may be composed of primitives such as spheres, or more complex shapes made by extruding polygons along the z axis and adjusting the vertexes. Materials are then
