About Blender software
● Blender is the free and open source 3D creation suite. It supports the entirety of the 3D
pipeline—modeling, rigging, animation, simulation, rendering, compositing and motion
tracking, even video editing and game creation.https://www.blender.org/

Scripting & Extending Blender »
Introduction
●
Introduction
● Python is an interpreted, interactive, object-oriented programming language.
It incorporates modules, exceptions, dynamic typing, very high-level dy-
namic data types, and classes. Python combines remarkable power with
very clear syntax.
● Python scripts are a powerful and versatile way to extend Blender functional-
ity. Most areas of Blender can be scripted, including animation, render-
ing, import and export, object creation and the scripting of repetitive
tasks.
● To interact with Blender, scripts can make use of the tightly integrated API.

Introduction
● General Information
● Links that are useful while writing scripts:
● Python.org – General information about Python.
● Blender Python API – Official API documentation. Use this for referencing while writ-
ing scripts.
● API Introduction – A short introduction to get you started with the API. Contains ex-
amples.
● Links that deal with distributing your scripts:
● Sharing scripts – Information on how to share your scripts and get them included in
the official Blender distribution.
● Creating Add-ons – Add-ons are used to encapsulate and distribute scripts.
● Add-ons project – Project to maintain a central repository of extensions to Blender.
