Spiral galaxy simulation

[waperboy]

Beautiful, but where is the h2? I only see stars and dust...

[deskmations]

at the end of the vid it looks like the other video icons are spinning. :O

[MarkArandjus]

Watch entire video. Look at your hand. Your hand is now a spiral galaxy. Trippy!

[Hekatonkheirus]

After watching this comments started to spin for me :) nice

You didn't consider the gravitational effect, of "Dark Matter", on the simulation :)

[beltoforion1]

Thats not entirely true since the gravitational effect of dark matter is implicitely contained in the radial velocity curve. But this is just a simulation of the visual appearance anyway.

[DKM101]

cool, though not technically a simulation. more of a demonstration/visualization of a theory.

[TheReasonWhyGuy]

This is with full interstellar gravity?

[beltoforion1]

My bad, since the article is unfinished i didnt upload any code. I have fixed this and the download link should work now. The code is for linux and requires SDL/OpenGL. In order to compile the code right away you need the CodeBlocks IDE.

thank you very much for your reply to my previous questions.

[mathcore85]

many thanks for the info!!!

is there a way to get the source form your page? (link seems broken)

[beltoforion1]

Sorry, i have to disappoint you. This is not a n.body simulation. The stars simply follow elliptical orbits that are rotated against each other with increasing radius. This was meant as an illustration to explain why spiral arms are stable (more details and the source code can be found at this page: beltoforion (dot) de (slash) galaxy (slash) galaxy_en.html (its still pretty incomplete)

[mathcore85]

this is awesome!!!!,

can you tell me more about this simulation? how do you solve the n-body problem? tree code method? direct methods? other?, how much time you need to run this simulation??

can you send me your code????,

im very interested in this kind of simulations
