Summary
In this chapter, we learned how to use Vector, Quaternion, and Matrix entities to our advantage, not to mention the different rotation modes. That gives us the elements for understanding and mastering the transformations in space and moving the objects in the scene.
We also learned how to create constraints in Python, which is very important in all set-up scripts.
Lastly, we learned how our operators can get user input and display their parameters inside the Blender user interface during their execution.
In Chapter 5, we will learn how to code our own panels for the graphic interface and make its options aware of the context.
