# JUFO18_GalaxyGeneration
__Generating Galaxies and Visualizing them using Blender.__
The Project began during my Intership at the
[ZAH](https://zah.uni-heidelberg.de/welcome/)
(Zentrum Für Astronomie der Uni Heidelberg) thank's to
[@tugi](https://github.com/tugi).
The Repo we created during that time can be found
[here](https://github.com/HanEmile/Heidelberg)
The Code is split up into two parts (03.12.17): The first part creates the
data using [Python](https://python.org) so the second part can visualize it in
[Blender](https://blender.org).
---
### HowTo:
- Generate the Lookup table:
$ ./lookup <where_to_save> <nr_of_stars>
Example:
$ ./lookup 42 1e7
- Generate the Coordinates:
$ ./coord <nr_of_stars> <where_to_save>
Example
$ ./coord.py 1000 11
- Display the Stars using Blender:
$ blender --python view.py -- <star_data_location>
Example
$ blender --python view.py -- 11
