Blender
(Version 2.4.7)
Blender is an advanced 3D modeling program capable of producing high quality animations, performing rendering, post-production, interactive creation and playback. It is the only 3D creation suite which allows the artist to model, texture, animate, render, and export the finished product in a package less than 10 MB.
The active development community is steadily adding new features and extensions such as the superb Yafray rendering engine for generating photo-realistic effects. Blender now also supports dynamic particle generation, advanced UV texture unwrapping methods using LSCM algorithms and much more. Blender natively exports to a multitude of 3D formats such as VRML, Cal3d, AC3D. With the powerful and easily extensible Python plugin support, you can write your own extensions or choose from a range of existing plug-ins.
With the recent user interface overhaul and the release of the 2.3 Blender User's guide, using Blender is easier than ever. Even so, 3D modeling remains a complex computing task, with the result that Blender is an extensive application with a steep learning curve. To help you get started we have included some comprehensive documentation and video tutorials.
