Blender is a free 3D graphics application. It can be used for modeling, UV unwrapping, texturing, rigging, water simulations, skinning, animating, rendering, particle and other simulations, non-linear editing, compositing, and creating interactive 3D applications. Blender is available for several operating systems, including Microsoft Windows, Mac OS X, Linux, IRIX, Solaris, NetBSD, FreeBSD, OpenBSD with unofficial ports for BeOS, SkyOS, AmigaOS, MorphOS and Pocket PC. Blender has a robust feature set similar in scope and depth to other high-end 3D software such as Softimage|XSI, Cinema 4D, 3ds Max, Lightwave and Maya.
These features include advanced simulation tools such as rigid body,
fluid, cloth and softbody dynamics, modifier based modeling tools,
powerful character animation tools, a node based material and
compositing system and Python for embedded scripting.
Blender has a depth and breadth of features comparable to commercial, proprietary, high end and mid range 3D software. In the month following the release of Blender v2.44, it was downloaded 800,000 times; this worldwide user base forms the core of the support mechanisms for
the program. Most users learn Blender through community tutorials and
discussion forums on the internet.
