Using the pre-provided three.min.js (global THREE), build a 3D solar system with the sun and orbiting planets at varied speeds and sizes, orbit-drag camera controls, and a starfield.

I will create a single self-contained index.html file that includes: - A 3D solar system with the sun and multiple planets of different sizes and speeds orbiting the sun. - Orbit drag controls for the camera. - A starfield background. - Use the pre-existing three.min.js by including <script src="three.min.js"></script>. I will build this in the index.html.

I have created index.html with a 3D solar system scene using three.min.js. It features the sun, orbiting planets with varied sizes and speeds, a starfield background, and drag orbit camera controls with zoom. You can open index.html in a browser to see it in action. Let me know if you want any changes or additions!

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

3/5 working

Sun with orbiting planets and starfield render correctly; drag zooms/pans camera, but keyboard input causes odd extreme zoom-ins.

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.
