I've been iterating on a small galaxy visualization project that originally started as a university course assignment, using only provided sample data (no real astronomical distances).

Recently, I updated it to include redshift-based distance data, which makes the 3D structure more meaningful and closer to real large-scale galaxy distributions.

Repo: https://github.com/Avicted/galaxy_visualization_raylib

Demo video (3D navigation + galaxy structures): https://www.youtube.com/watch?v=fC83RDWuPvw

Current state:

- Written in C (C99 standard) using Raylib

- Realtime 3D visualization with free camera movement

- Uses redshift values to approximate distances

- Cross-compiled builds via mingw64 (Linux & Windows releases on GitHub)

Still very much a learning / exploration project

There's plenty that could be improved (accuracy, performance, interaction, visuals), but I figured I'd share the update in case it's interesting or sparks suggestions.

Happy to hear feedback or pointers to better approaches or datasets. Thanks!
