Blender 2.49 Scripting: Shape Keys, IPOs, and Poses

by Michel J. Anders | April 2010 | Open Source

The Blender API provides us with the means to define IPOs from scratch, enabling the definition of movements not easily re-created by setting key frames by hand. Thus there is more to IPOs than just driving one IPO by another one. Furthermore, Shape keys and poses are examples of (collections of) IPOs that are quite different from, for example, a location IPO. We will encounter both shape keys and poses later on in this article, but we will start off with looking at how we might define an IPO from scratch.

In this article by Michel Anders, author of Blender 2.49 Scripting, you will learn how to:

  • Define IPOs
  • Define shape keys on a mesh
  • Define IPOs for those shape keys
  • Pose armatures
  • Group changes in poses into actions

(Other related articles on Blender 2.49 Scripting are listed at the end of this page.)
