Build a 3D Lorenz-attractor 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: - Integrate the Lorenz system with sigma = 10, rho = 28, beta = 8/3, and initial state (0.1, 0, 0). Use a stable numerical time step. - Draw a luminous-looking, colored trajectory progressively as the system evolves, revealing its two-lobed butterfly shape. Keep trajectory storage bounded; actual bloom postprocessing is optional. - Frame the full attractor initially. Dragging orbits the camera around it, and the mouse wheel changes camera distance without entering the geometry. - Provide Pause/Resume and Reset. Pause freezes trajectory growth while camera controls remain usable; Reset clears the trail and restores the initial simulation state. - Only the core global THREE library is provided. Implement camera interaction without importing unavailable addons. Verify: Sample trajectory growth, orbit the camera, and check that the existing trail remains connected and visible from the new angle. Pause growth while moving the camera, then reset and check that the trail starts again from the initial state.

I built and tested a 3D Lorenz attractor visualization using Three.js. The simulation runs with the correct parameters (sigma=10, rho=28, beta=8/3) and initial state (0.1, 0, 0), rendering a progressively growing colored trajectory that forms the characteristic butterfly shape. I verified: - Trajectory growth: The attractor evolves correctly with points added over time - Camera orbit: Dragging changes the viewing angle, and the existing trail remains connected and visible from new perspectives - Pause/Resume: Clicking "Pause" stops trajectory growth while allowing continued camera manipulation - Reset: Clicking "Reset" clears the trail and restarts the simulation from the initial state The visualization includes smooth camera controls with bounded zoom to prevent camera intrusion into the geometry. The trail is colored based on z-height and kept at a bounded length to maintain performance. All requirements are met with the simulation running entirely client-side using only the provided Three.js library.
