Author data-visualization and math-visualization scenes in ecmanim — the D3-parity foundation (scales, shape generators, hierarchy layouts, force simulation, sankey/chord, contours/hexbin/topojson, dataJoin for enter/update/exit), chart mobjects (PieChart…
Author, render, and iterate on ecmanim animations (a TypeScript port of manim that renders the same Scene code in Node and the browser). This skill should be used when the user wants to create or edit a Manim-style programmatic animation with ecmanim, render…
Interchange and fidelity workflows for ecmanim — playing back real animated Lottie/Bodymovin files (`loadLottie` → `LottieMobject`, scrub-safe keyframes/masks/mattes/precomps), exporting/importing static Lottie shape JSON (`loadLottieShapes`), exporting…
Author physics visualizations in ecmanim — analytic electromagnetic fields (point charges, current loops), traveling/standing waves, paraxial thin-lens optics, rigid-body simulation (pendulum, gravity/floor drops, pluggable planck.js/@dimforge/rapier2d…
Build slide-style/presentation ecmanim scenes — automatic shared-element transforms between two mobject states (TransformMatchingAuto, identity-keyed not position-keyed, plus Scene.autoAnimateToNextSection() and the GSAP-style FLIP helper), presenter/slide…
Covers the `ecmanim` command-line tool — the render/plan/cfg/init/plugins/checkhealth subcommands, render flags (-q quality presets, -f output formats, -o output path, -t transparent, -a write_all, -n from_upto, --save_sections), the manim.config file, the…
Sequence and time ecmanim animations with the GSAP-style Timeline position grammar, drive properties with pure expression functions (wiggle/remap/ramp/compose), distribute per-element delays with stagger helpers (cycle/staggerRange/staggerGrid +…
Practical field guide for authoring ecmanim scenes — layout math that prevents clipped/off-center output, a verification discipline that catches problems before they reach the user, working layout helpers (frame geometry, measured text width, Axes centering),…
Covers ecmanim's own prompt-to-video layer, the "ecmanim/authoring" subpath — plan-IR generation via toPlanIR() (a dry-run that harvests scene structure without rendering), the ecmanim plan CLI, quality gates (runQualityGates, slideshowRisk,…
Add burned-in captions and audio-reactive visuals to ecmanim scenes — SRT parse/serialize, TikTok-style word-by-word karaoke caption pages, an on-screen CaptionTrack overlay, and audio analysis (PCM decode, FFT/getAudioData/visualizeAudio, waveform slices)…
Run ecmanim's live-reload dev server (startStudio() from ecmanim/studio — serves a Scene in a <manim-player>, watches files, and hot-reloads the browser via SSE on save) and convert a defineSchema() spec into props-panel control descriptors…
Add TTS-synthesized narration to an ecmanim Scene via voiceover(), sync animations to speech with bookmark tags and the returned duration tracker, and configure or extend the TTS provider abstraction (system/openai/elevenlabs/silent, custom providers, env-key…
