Built `index.html` — self-contained Lorenz butterfly with `three.min.js` (global `THREE`): - **Physics**: RK4 integration of Lorenz equations (σ,ρ,β editable), 30k points, scaled & centered, z-up orientation - **Drawing over time**: incremental `BufferGeometry.setDrawRange` revealing trail at adjustable speed; scrub bar to seek, pause/play, clear/reset, looping - **Glowing butterfly**: additive `Line` core + wider translucent glow line + `Points` bloom + emissive head sphere + two PointLights colored by velocity/theme (velocity → brightness/saturation) - **Color themes**: Nebula / Sunset / Arctic / Inferno mapping t→HSL with velocity boost - **Orbit-drag**: custom OrbitControls (no imports) — drag to orbit, wheel/pinch zoom, right-drag pan, Shift-slow, double-click focus, auto-orbit toggle, damping - **Extras**: starfield, grid/axes, exponential fog toggle, trail persistence, glow/size sliders, snapshot export, FPS/polar stats

RUN
EVALUATION
Lorenz butterfly trajectory draws and glows nicely; drag/wheel rotate camera but FPS drops sharply over time.
Vision grade · anthropic/claude-sonnet-5
MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
