MakeHuman is a free, open source, interactive modeling tool for creating custom 3D human characters. These characters can be modeled in minutes and can then be used with many other modeling and rendering programs to incorporate realistic human figures into computer generated images and animations. Features that make this software unique include the tetra-parametric GUI© and the Natural Pose System©, for advanced muscular simulation.

Unlike most 3D software, where 3D objects are usually created from scratch, DAZ Studio is designed to allow users to manipulate "ready to use" models and figures. It is aimed at users who are interested in posing human figures for illustrations and animation, but who may be daunted by more technical 3D and CAD software. It was created by DAZ Productions, the company that creates the built-in content for Poser 3, 4, 5, 6 and 7 as a direct alternative to Poser.

XnaPosingStudio is a "XNA Model Viewer" and 3D posing software based on (and compatible to) XNALara, for any 3D character. With a rather rudimentary way to make a keyframe animation. Free of charge.--DeviantArt hub with tutorials and galleryhttp://xnalaraitalia.deviantart.com/
