Show HN: Interactive 3D WebGL Globe for real-time daylight cycles

https://github.com/azialle/Oclock
2•codechibi•1h ago
Oclock is an interactive 3D WebGL globe that visualizes real-time daylight cycles. Built with Globe.gl and pre-processed spatial data pipeline.

Processing Pipeline

The data generation is handled by timezone_data_generator.py. This script performs the following:

1. Geometry Analysis: Uses shapely to find a representative point inside each country's boundary.

2. Timezone Mapping: Uses timezonefinder to look up the specific IANA timezone string for those coordinates.

3. Data Injection: Injects the timezone and coordinates back into the GeoJSON properties for use by the frontend.

Live Demo: https://azialle.github.io/Oclock/

I wanted to visualize global time and daylight cycles in a way that moved beyond the typical 2D map or static list. By using a custom spatial data pipeline and a 3D visualization engine, I built Oclock to render the Earth's day-night interface within a real-time, interactive environment. This is an open-source project, and I’d love for the community to check it out!

Cool visualization! It’s satisfying to navigate the 3D globe and see the daylight transitions in real-time. I looked into the project and thanks for sharing the Python code you used for generating the GeoJSON data. Starred on GitHub!
