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.

**Visualizing the Attractor**

I'm currently focused on rendering the Lorenz attractor within a single HTML file, using three.min.js for 3D graphics. The goal is to create a self-contained visualization without relying on external resources.


**Implementing the Equations**

Now, I'm working on coding the Lorenz attractor's differential equations and integrating them into the Three.js scene. I've defined the standard constants and am focusing on the animation aspect—how to draw the attractor over time. A "glowing" effect is also in mind. I also need to make progress on a simple orbit-drag controller with the provided `three.min.js`.

**Constructing Initial Framework**

I've initiated the planning phase for `index.html`. My focus is currently on setting up the Three.js scene and dynamically computing the Lorenz attractor trajectory points, all while planning to integrate `three.min.js`. The next step involves updating the line geometry over time and creating a basic mouse-drag camera controller.

The Lorenz attractor visualization is now contained in `index.html`. It uses `three.min.js` to render the trajectory dynamically in a glowing, additive-blended style. You can rotate the camera by clicking and dragging on the screen.

TAKE IT TO CODE

A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.

EVALUATION

4/5 working

Cyan glowing Lorenz attractor draws itself over time and rotates smoothly with drag; other inputs have little effect.

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.
