This is an example project to show how to render a Galaxy in OpenGL on the iPhone. To simulate interstellar dust realistically with unsorted point sprites in OpenGL, I've implemented a GPU based ray tracing algorithm. This Milky Way model is used in the Exoplanet App. The Exoplanet App is available for free on the AppStore and contains several other datasets.
I gave a talk about this project at the New York iOS Meetup in January 2013. The slides of the talk are included in this repository. If you have any comments, questions or suggestions for improvements, please send me an e-mail: exoplanet@hanno-rein.de.
