Anime.js — Powerful Animations for 2D, UI, and Three.js Scenes

Anime.js is a lightweight yet powerful JavaScript animation library that works beautifully alongside Three.js to create smooth, expressive 3D animations. While it’s widely known for animating DOM elements and SVGs, it also excels at animating JavaScript objects — making it a great fit for controlling cameras, lights, materials, and object transforms inside a Three.js scene.

By animating properties like position, rotation, scale, opacity, or custom shader values, Anime.js can drive complex 3D motion with minimal setup. Its timeline system allows you to choreograph sequences, synchronize multiple objects, and create cinematic transitions that feel fluid and natural.

Anime.js is especially useful for:

• Camera movements and fly-throughs

• Object transformations and reveals

• Material and light animations

• Coordinated UI and 3D scene interactions

With its simple API and excellent performance, Anime.js complements Three.js by handling animation logic cleanly while letting Three.js focus on rendering. It’s an ideal choice for interactive websites, product showcases, and creative WebGL experiences where precise timing and smooth motion matter.
