Blender is an open-source 3D modeling and rendering program that lets you create professional-quality animations. It features a huge variety of creation tools such as 3D paint, 2D and 3D procedural brushes, polygon meshes, textures, collision simulation, edge rendering, and support for numerous 2D and 3D file formats. This free software is not very easy to use if you have no practice of 3D rendering tools, but many tutorials are available on the editors website.
