Learn THREEJS-ANIMATION with Real Code Examples

Install: npm install three

Import core modules including AnimationMixer

Load GLTF animations via GLTFLoader

Initialize mixer for animated objects

Call mixer.update(deltaTime) inside render loop

Ensure correct rendering loop

Use Clock for delta time

Confirm GLTFLoader version matches Three.js

Check browser WebGL support

Use light scenes for mobile

vite.config.js - bundling

three.config.js - optional scene config

model-export-settings.json - GLTF export prefs

package.json - dependencies

tsconfig.json - TypeScript support

npm install three

npm run dev

npx vite build

npm run preview

npx gltfjsx model.gltf (for R3F)

Text independent from animations

Cameras may follow different UI layouts

Cinematic pacing may need local adjustments

3D assets localized via GLTF metadata

Animations remain universally consistent

Provide alt text for 3D elements

Allow pause/skip controls

Avoid essential content behind fast motion

Use reduced motion when required

Ensure keyboard input does not disrupt animations

Sync UI transitions with animations

Update DOM overlays via GSAP

Blend camera animations with user input

Use easing in tracks for smooth motion

Match lighting changes with animations

Actions store animation state

Mixer manages active clips

Blend weights combine animations

Track values update object properties

External UI triggers change animation state

Store clips in reusable arrays

Keep animation lengths consistent

Use baked GLTF animations

Avoid too many keyframes

Prefer compressed GLTF (Draco/KTX2)
