Atmosphere & Night Visual Enhancement Prompt

Building a 3D Earth Visualization Using OpenAI Codex

1. Open the OpenAI Codex (Coding Agent) interface in your web browser.
2. Enter the main prompt in the input field to create an interactive 3D map that can zoom from outer space down to city streets.
3. Locate the 'Reasoning Effort' settings menu within the interface.
4. Select the 'Extra High' setting to ensure the AI generates high-quality, high-performance code.
5. Click the 'Run' button to start the process of generating the code and folder structure.
6. If the initial result isn't quite right, provide an additional prompt (iteration) to add layers such as dynamic clouds and atmosphere.
7. Use a specific prompt to utilize 'publicly available assets' to ensure the Earth and cloud textures look realistic.
8. Add instructions for a 'Day and Night toggle' feature so that city lights become visible at night in densely populated areas.
9. Once the AI finishes generating all files, navigate to the automatically created project folder.
10. Find and double-click the 'index.html' file to view your 3D map in the browser.
11. Use the generated UI toggles to turn the 'Clouds', 'Atmosphere', and 'Spin' functions on or off.
12. Click on a city name (e.g., New York or Tokyo) to test the automatic zoom feature to that city's 3D rendering level.
