API Info

• Blender API Change Log

Note

The Blender Python API has areas which are still in development.

The following areas are subject to change.

• operator behavior, names and arguments
• mesh creation and editing functions

These parts of the API are relatively stable and are unlikely to change significantly

• data API, access to attributes of Blender data such as mesh verts, material color, timeline frames and scene objects
• user interface functions for defining buttons, creation of menus, headers, panels
• render engine integration
• modules: bgl, mathutils & game engine.
