10 open-source motion libraries for Opus 5.5
The author argues that instead of telling Opus 5.5 to make motion "smooth," you should give it specific curves, springs, and durations, and lists 10 motion repos including motion-canvas, theatre.js, and manim.
stop telling Opus 5.5 to make motion “smooth” that word is doing almost no work give it curves, springs, durations and actual motion systems instead and the output gets way more predictable I pulled 10 GitHub repos that are useful for exactly that: 1. motion-canvas TypeScript animations with generators + real-time preview. great when you want every beat tied to an exact timeline http://github.com/motion-canvas/motion-canvas 2. theatre.js high-fidelity motion graphics for HTML, SVG and 3D. code + visual editing in the same system http://github.com/theatre-js/theatre 3. mo.js shapes, bursts, staggers and swirls. much better primitives than “make it feel dynamic” http://github.com/mojs/mojs 4. mo.js curve editor live editing for custom easing and property curves http://github.com/mojs/mojs-curve-editor 5. popmotion keyframes, springs and decay animations for numbers, colors, strings and SVG paths http://github.com/Popmotion/popmotion 6. react-spring spring-physics-first animation for React, React Native and Three http://github.com/pmndrs/react-spring 7. auto-animate one-line transitions for DOM changes. simple enough for Opus to inspect and reuse fast http://github.com/FormKit/auto-animate 8. barba.js page-transition engine for fluid site navigation and state changes http://github.com/barbajs/barba 9. ant-motion Ant Design’s motion specification + React animation components with tweening and Bezier motion http://github.com/ant-design/ant-motion 10. manim a full programmatic animation engine built around precise, reproducible motion http://github.com/ManimCommunity/manim instead of: > make it smoother > make the bounce subtle > make it feel cinematic give Opus: > 420ms duration > 32px travel > spring stiffness 170 > damping 22 > 80ms stagger less adjectives, more numbers that’s when the motion stops being a guess ↓
