Blender 3D - Creation Suite

Blender is the free open source 3D content creation suite, available for all major operating systems.



Features

• Revolutionary non-overlapping and non-blocking UI delivers unsurpassed workflow
• Flexible and fully configurable window layout with as many screen setups as you prefer
• Undo support on all levels
• Anti-aliased fonts with international translation support
• Any window space can be easily switched to any window type (curve editor, NLA, 3D view etc)
  
• Built-in text editor for annotations and editing Python scripts
• Graphical user interface for Python scripts
• Custom themes
• Consistent interface across all platforms

Animation

• Armature (skeleton) deformation with forward/inverse kinematics with pole target support
• Auto IK allows posing FK chains easily
• Non-linear animation editor for mixing individual actions created in Action editor
• Automated walkcycles along paths
• Animated constraint system
• Vertex key framing for morphing, with controlling sliders
• Edit and create new blendshapes from existing targets
• Character animation pose editor
• 'Ipo' system integrates both motion curve and traditional key-frame editing
• Audio playback, mixing and editing support for sound synchronisation
• Timeline offers fast acces to many playback functions, autokey, help markers
• Python scripting access for custom and procedural animation effect

Modeling

* A range of 3D object types including polygon meshes, NURBS surfaces, bezier and B-spline curves, metaballs, vector fonts (TrueType, PostScript, OpenType)
* Very fast Catmull-Clark subdivision surfaces with optimal iso-lines display and sharpness editing
* Full multiresolution sculpting capabilities with 2D bitmap/3D procedural brushes (Paint, Smooth, Pinch, Inflate, Grab) supporting symmetry
* Modifier stack deformers such as Lattice, Curve, Armature or Displace
* Mirror modifier with middle vertices clipping and automatic deletion of inner faces
* Non destructive real time Boolean and Array modifiers
* Mesh modeling based on vertex, edge and/or face selection
* Smooth soft selection editing tools for organic modeling
* Python scripting access for custom tools
