Learn THREEJS-ANIMATION with Real Code Examples
Updated Nov 26, 2025
Practical Examples
Rotating object animation
Morph target facial animation
Character walk/idle/run blending
Camera dolly and path animation
Full GLTF character action system
Troubleshooting
Ensure mixer.update(delta) is called every frame
Check root object is compatible with animation
GLTF animations must be inside model.animations[]
QuaternionTrack rotation mismatch issues
Incorrect keyframe lengths cause jitter
Testing Guide
Validate clip lengths
Confirm keyframe values animate correctly
Test blending between tracks
Unit-test animation triggers
Test mixer.tick accuracy
Deployment Options
Standard Web deployment
Static hosting (Vercel/Netlify)
Parcel/Vite/Webpack bundlers
NPM package bundling
SSR disabled for animation-heavy scenes
Tools Ecosystem
GLTFLoader + GLTF animation tools
Blender for GLTF animation authoring
Mixamo for rigged characters
GSAP for timeline control
three-std/three-stdlib utilities
Integrations
GSAP timeline control
React Three Fiber (R3F) animation hooks
Three.js + Cannon.js physics sync
WebGPU (upcoming Three.js renderer)
WebXR for VR/AR animation
Productivity Tips
Use gsap.to for hybrid timelines
Bake animations in Blender for accuracy
Leverage GLTF morph targets
Cache mixers and clips
Use animation helpers (SkeletonHelper)
Challenges
Managing multiple mixers
Synchronizing animations with input
Maintaining correct quaternion rotations
Reducing asset size for web performance
Complex timeline sequencing without an editor
