Blender is the open source software for 3D modeling, animation, rendering, post-production, interactive creation and playback. Available for all major operating systems under the GNU General Public License.
* Revolutionary non-overlapping and non-blocking UI delivers unsurpassed workflow
* Flexible and fully configurable window layout with as many screen setups as you prefer video sequence editing, character animation action editor, non-linear animation mixer, image/UV editing, file/image selection and file management
* Built-in text editor for annotations and editing Python scripts
* Consistent interface across all platforms
* A range of 3D object types including polygon meshes, NURBS surfaces, bezier and B-spline curves, metaballs, vector fonts (TrueType, PostScript, OpenType)
* 'Smooth proxy' style catmull-clark subdivision surfaces with optimal iso-lines display and sharpness editing
* Armature (skeleton) deformation with forward/inverse kinematics, auto skinning and interactive 3D paint for vertex weighting
* Non-linear animation mixer with automated walkcycles along paths
* Constraint system
* Vertex key framing for morphing, with controlling sliders
* Oversampling, motion blur, post-production effects, fields, non-square pixels
* Environment maps, halos, lens flares, fog
* Various surface shaders such as Lambert, Phong, Oren-nayar, Blinn, Toon
* Edge rendering for toon shading
* Procedural Textures
* Graphical editor for defining interactive behavior without programming
* Collision detection and dynamics simulation
* Playback of games and interactive 3D content without compiling or preprocessing
* Audio, using the SDL toolkit
* Multi-layering of Scenes for overlay interfaces
* And much much more
