6. X, Y, and Z
• X, Y, and Z are axis lines
• In 2D animation, when you’re using a piece of paper, X is left to right
and Y is up and down
• In 3D animation, we add in depth, the Z-axis
8. Empty (Null): an empty object that doesn’t have points or
surfaces, but can be used as one or more objects’ parent
9. Parent/children: (barrel of monkeys chain): parent is an object at
