Prompt for this run

Build a 3D solar-system visualization using the provided Three.js library. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. Use the provided `three.min.js` (global `THREE`) through a plain local script tag; the runner will inline it into the final artifact. Required behavior: - Show the Sun and all eight planets, with distinguishable colors, readable labels, and orbital paths against a procedural starfield. - Animate planets orbiting the Sun at different speeds. Use schematic sizes and distances for visibility; scientific scale accuracy is not required. Inner planets should generally orbit faster than outer planets. - Initially frame the complete system. Dragging orbits the camera around the Sun, and the mouse wheel changes camera distance within usable bounds. - Provide Pause/Resume and Reset view. Pause freezes planetary motion while leaving camera controls usable; Reset view restores the initial camera framing. - Generate materials and geometry procedurally. Only core global THREE is available; do not import additional controls or texture files. Verify: Inspect the initial planet labels and sample orbital motion. Orbit the camera and check that the system stays visible. Pause the simulation while adjusting the camera, then use Reset view and compare the initial framing.

I have Three.js r128 (no OrbitControls — I'll write custom camera controls). Let me build the app.

The screenshot/motion frames aren't viewable in this model, so I'll add a temporary telemetry overlay to verify behavior via DOM inspection, then remove it.

Done — `index.html` is in `/tmp/job-olMTw8/` (10.6 KB, fully self-contained: inline CSS/JS, loads `three.min.js` via a plain local `<script src="three.min.js">`, no CDNs/external assets). **What I built** - Sun (basic material + additive glow), 8 planets (Phong material, distinct colors, Saturn has a procedural ring), canvas-texture sprite labels above each planet, colored orbital lines per planet, and a procedural 2,600-point starfield. - Animation loop with dt-clamped orbit speeds decreasing outward (inner planets orbit faster), plus self-rotation. - Drag-to-orbit and wheel-zoom camera controls (custom, since OrbitControls isn't in core). Reset view restores the initial framing; Pause/Resume freezes only planetary motion — camera controls stay live. **What I verified in the browser** - Clean console (only benign GL driver performance warnings, no JS errors). - Initial framing fits the whole system: camera at θ=0.55, φ=1.10, dist=112 with 60° FOV vs. outermost orbit radius 39. - Orbital motion: a debug-readout of Earth's orbit angle advanced across snapshots (1.52 → 2.51 → 4.84 → 7.23 rad), confirming animation runs. - Drag: orbiting the camera changed θ 0.55 → −0.05, φ → 1.70, still rendering fine. - Reset: after orbiting, clicking Reset restored exactly θ=0.55, φ=1.10, dist=112.0. - Pause/Resume: button toggles correctly and gates the per-frame motion; camera handlers are independent of the pause flag. **Unverified** - Wheel zoom: the harness's scroll action did not register as a `wheel` event on the canvas (it dispatches scroll, not wheel), so distance didn't change in testing. The handler is a standard non-passive `wheel` listener (dist = dist·e^(deltaY·0.0012), clamped to [18, 480]) — code-reviewed but not exercised. - Visual appearance (label legibility, glow, ring) couldn't be inspected because this model can't receive screenshot images; construction is verified error-free. - Pause state isn't persisted across page reloads (by design, resets on reload). I temporarily added an unobtrusive debug readout to drive the checks above, then removed it; the final artifact is clean.
