JUFO18_GalaxyGeneration

Generating Galaxies and Visualizing them using Blender.

The Project began during my Intership at the ZAH (Zentrum Für Astronomie der Uni Heidelberg) thank's to @tugi.

The Repo we created during that time can be found here

The Code is split up into two parts (03.12.17): The first part creates the data using Python so the second part can visualize it in Blender.

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
