It doesn't move
by itself. Someone
poses it, twice.

In short: 3D animation is a set of poses recorded at key moments, and the computer smoothly fills in everything in between. In AR, those poses can be triggered by a tap or your movement instead of playing on a fixed timer. Tap the screen below.

Tap to animate Recorded
pose

Three poses were recorded: crouch, mid-jump, landed. Everything you see moving between them was calculated automatically, nobody drew it frame by frame.

How it's built

Like stop-motion, but the computer draws the in-between pictures

An animator records a few key poses. The software calculates every frame in between on its own.

1 Record a pose The animator sets the model's position at one exact moment, a crouch, an open hand, a raised head.
2 Record another A second pose is set further along in time, mid-jump, arm extended. These two are the keyframes.
The computer fills the gap Every frame between the two keyframes is calculated automatically, that's what makes the motion look smooth.
Not a movie, a response

A film plays start to finish. AR animation waits for you

The recorded poses don't change, but what starts them does. Three common triggers.

A tap Touching the object starts its reaction, a wave, a spin, an open mouth.
Walking closer A location-anchored object senses proximity and wakes up as you approach it.
A gesture A hand movement or head turn triggers a transformation instead of a menu tap.
Why bother animating it

A static logo sits there. A mascot notices you

Same brand, same 3D model. One difference: whether it moves when you show up.

No animation Looks exactly the same every time it's viewed, no matter what you do.
Animated Reacts, notices you're near, feels present instead of pasted on.
Not concept art. Shipped work.

Two real, animated examples

Quick answers

What's the difference between a 3D model and 3D animation?

A 3D model is the static shape, the mesh, texture, and material. Animation is a separate layer on top: recorded poses that tell the same model how to move over time.

What is a keyframe?

A keyframe is a pose recorded at a specific point in time, like a crouch or a jump. The computer calculates every frame between two keyframes automatically, so the motion looks smooth without anyone drawing each step.

How is AR animation different from a movie?

A movie plays the same animation in the same order every time. In AR, animations are usually triggered by what you do, a tap, a gesture, or walking closer, so the same object can respond differently depending on the moment.

Do all AR objects need animation?

No. A static product or logo works fine anchored in place. Animation gets added when a brand wants the object to feel alive, noticing you, reacting to a tap, or transforming into something else.
