When will I use Transformations?

I have had a lot of you asking:
"What good are transformations to me?"
"When will I use this information!"

Computer animations, especially something like the animated cartoon movie Toy Story or Monster's Inc., all use transformations of their shapes to get the figures to move around on the screen. Of course, these artists who create the motion pictures are allowed to use computers that help them with these mathematical calculations. We are learning the basic background of being able to move an object in space. Putting calculations together, we could create a computer animation using these transformation rules.
