Using the pre-provided three.min.js (global THREE), visualize the Lorenz attractor as a glowing 3D butterfly trajectory that draws over time, with orbit-drag camera controls.
I'll create a self-contained 3D Lorenz attractor visualization with Three.js. Let me first check the current directory and then build the app.

Now I'll create the complete `index.html` file with the Lorenz attractor visualization:

The Lorenz attractor visualization is complete! Here's what I built: **Features:** - **3D Lorenz Attractor** - The butterfly trajectory draws in real-time with glowing particles - **Orbit Camera Controls** - Drag to rotate, scroll to zoom - **Glowing Particles** - Custom shader with additive blending creates a beautiful glow effect - **Color Gradient** - Trail transitions from blue → cyan → magenta → pink → purple - **Interactive Controls**: - Speed slider (0.1x to 5x) - Trail length (100 to 5000 points) - Glow intensity control - **Real-time Stats** - Point count and FPS display - **Subtle Auto-rotation** - Camera slowly rotates when not interacting **Technical Details:** - Uses Three.js (loaded from local `three.min.js`) - Custom GLSL shaders for the particle glow effect - Exponential fog for depth perception - Additive blending for the glowing trail effect - Fully self-contained in one HTML file with no external dependencies Open `index.html` in a browser to see the mesmerizing butterfly-shaped Lorenz attractor unfold in 3D space!

EVALUATION
Glowing cyan Lorenz-like curve draws over time with sliders; drag rotates camera clearly, but shape looks overly thick/blobby not butterfly-like.
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.
