Blender 2.45 Final

Open source software for 3D modeling, animation, rendering which also features a game engine Blender is an open source software for 3D modeling, rendering, animation, post-production, interactive creation and playback. Available for Windows, Linux, Irix, Sun Solaris, FreeBSD or Mac OS X.
Modeling
- 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
- Boolean mesh functions
- Editing functions such as extrude, bevel, cut, spin, screw, warp, subdivide, noise, smooth Soft selection editing tools for organic modeling
- Python scripting access for custom tools
Animation
- 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
- Character animation pose editor
- Animatable lattice deformation
- Ipo system integrates both motion curve and traditional key-frame editing
- Audio playback, mixing and editing support for sound synchronisation
- Python scripting access for custom and procedural animation effects
Realtime 3D/game creation
- Graphical editor for defining interactive behavior without programming
- Collision detection and dynamics simulation
- Python scripting API for sophisticated control and AI, fully defined advanced game logic
- Supports all OpenGL lighting modes, including transparencies, Animated and reflection-mapped textures
- Playback of games and interactive 3D content without compiling or preprocessing
- Audio, using the fmod toolkit
- Multi-layering of Scenes for overlay interfaces
Rendering
- Very fast inbuilt raytracer
- Integral support for the famous Yafray render engine
- 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
- Ambient Occlusion
- Radiosity solver
- Export scripts available for external renderers such as Renderman (RIB), Povray, Virtualight
- UV texture editor with various mesh unwrap modes
Interface
- Flexible user configurable window layout
- Powerful object-oriented data system
- Anti-aliased fonts with international translation support
- Windows for animation curves/keys, schematic scene diagram, non-linear video sequence editing, character animation action editor, non-linear animation mixer, image/UV editing, file/image selection and file management
- Inbuilt text editor for annotations and editing Python scripts
- Consistent interface across multiple platforms
Files
- Save all scene data in a single .blend file
- .blend format supports compression, digital signatures, encryption, forwards/backwards compatibility and can be used as a library to link to from other .blend files
- Read / Write TGA, JPG, PNG, Iris, SGI Movie, IFF, AVI and Quicktime GIF, TIFF, PSD, MOV (Windows and Mac OS X)
- Native import and export for DXF, Inventor and VRML files, with python scripts available for many other 3D formats
- Create stand-alone executables containing interactive 3D content or play back with the 3d web browser plugin
