Benefits of calling methods interactively

You can call methods interactively in sequence during the development process, providing the ability to:

• Set the stage more precisely than dragging objects with the mouse.
   
• Create and evaluate short animation sequences one step at a time before writing them into your animation program.

I will explain both of these processes later in this lesson.

Before I get to that, there is another important topic that I need to explain:  the position of objects in 3D space.
