 A wide variety of import/export scripts that extend Blender capabilities (accessing the object data via an internal API) make it possible to interoperate with other 3D tools.Blender organizes data as various kinds of "data blocks", such as Objects, Meshes, Lamps, Scenes, Materials, Images and so on.An object in Blender consists of multiple data blocks – for example, what the user would describe as a polygon mesh consists of at least an Object and a Mesh data block, and usually also a Material and many more, linked together.
