Hi, I would like to present my galaxy model.
Inspired by the M31 galaxy picture from http://apod.nasa.gov/apod/image/0611/andromeda_gendler.jpg, I tried to model a realistic galaxy. I used meshes with only vertices and Halos to create many points in the shape of a galaxy. The shape was mostly generated by a script.
The .blend file can be downloaded at
The scripts I used and documentation can be found at
