Blender
Blender is a free open source 3D graphics program, available under the GNU General Public License for the Linux, Mac OS X, FreeBSD, OpenBSD and Microsoft Windows operating systems.
Blender's features include 3D modeling, UV unwrapping, texturing, rigging, water and smoke simulations, skinning, animating, rendering, particle other simulations, video editing software, compositing, the ability to create interactive 3D applications, video games, animated film, or visual effects. More advanced tools include rigid, realistic body, fluid, cloth and softbody dynamics simulation, modifier-based modeling, character animation, a node-based material and compositing system, and embedded scripting in Python.
Support
The worldwide user base forms the core of the support mechanisms for Blender. Most users learn Blender through community tutorials and discussion forums on the internet such as Blender Artists [1] (previously known as elYsiun); however, another learning method is to download and inspect ready-made Blender models.
Numerous other sites, for example BlenderArt Magazine[2]—a free, downloadable magazine with each issue handling a particular area in 3D development—and BlenderNation, provide information on everything surrounding Blender, showcase new techniques and features, and provide tutorials and other guides.
