Blender is a free multi platform, dedicated to the creation and modeling of three-dimensional graphics, and the creation of movies and video games in three dimensions.
It has a fantastic and very unique graphical user interface, has been criticized as not very intuitive based on the classical system of windows, but has significant advantages over these, and to customize the menus and layout views camera.
Accommodates a variety of shapes, including curves, polygonal meshes, empty, NURBS and metaballs.
Along with the animation tools including inverse kinematics, deformations or grid reinforcement, and particle vertex of static and dynamic loading.
Tea tools audio editing and synchronization of video and interactive features for games such as collision detection, dynamics and logic recreations.
It offers versatile possibilities of rendering and internal and external integration with the powerful ray tracer or "Raytracer" free Yafray.
Accept graphics formats such as TGA, PNG, JPG, Iris, SGI and TIFF. You can also read Inventor files.
It includes a 3D gaming engine integrated with a system of logic bricks. For more control, and to automate and control multiple tasks, use the programming language Pyton.
Dynamics simulations for softbodies ago, particles and fluids.
Stackable switches, for the application of non-destructive processing on meshes.
There are current projects that have started to use it professionally, as the movie Spiderman 2, "Friday or Another Day" or Elephants Dream 2, experiments are extended capabilities thanks to the ability to edit the source code , bringing this experience to other users with basic innovations such as a control system of gestures (Morph System), a system of composition and texture of post production (Composite) and static particle system to simulate hair coats and that s' have added new properties to achieve realistic textures, among others.
Currently supports all versions of Windows, Linux, Solaris, FreeBSD, IRIX and Mac OS X. Its installation is simple, its use is somewhat complex to learn even for users of other 3D programs, but once it controls the interface is flexible and attractive.
