Understanding Animation

Req 1a — What Is Animation?

1a.

In your own words, describe to your counselor what animation is.

The Core Idea

At its simplest, animation is the art of creating the illusion of movement from still images. Your brain does most of the work — when you see a series of slightly different pictures shown one after another fast enough, your brain fills in the gaps and perceives smooth, continuous motion.

This trick relies on a concept called persistence of vision. Your eyes briefly hold onto an image after it disappears. When the next image appears an instant later, your brain blends the two together. Show enough images per second, and a bouncing ball on paper becomes a bouncing ball in motion.

More Than Just Cartoons

When most people hear “animation,” they think of cartoons — and cartoons are a huge part of the field. But animation reaches far beyond entertainment:

Medicine: Animated 3D models help surgeons plan complex operations and help patients understand their diagnoses.
Architecture: Architects create animated walkthroughs of buildings that do not exist yet, letting clients “walk through” a design before construction begins.
Science: NASA uses animation to simulate spacecraft trajectories, visualize weather systems, and model distant galaxies.
Education: Animated diagrams in textbooks and online courses make tough subjects — like how a cell divides or how an engine works — easier to understand.
Courtrooms: Lawyers use animated reconstructions to show juries how an accident or crime may have occurred.

Building Your Description

Your counselor wants to hear your own words, not a memorized definition. Here is a framework to help you organize your thoughts:

Start with the basics. What is happening technically? (Still images shown rapidly to create the illusion of movement.)
Explain why it works. What does your brain do with those images? (Persistence of vision fills in the gaps.)
Give examples. Where do you see animation in daily life? (Movies, games, apps, weather maps, medical imaging.)
Share what excites you. What aspect of animation interests you the most?
