Note: due to rendering of points, please watch the HD version, else you'll only see a blurry mess!
Galaxy model generated procedurally for the MMO Infinity :
This is a work-in-progress and does not necessarily represent the final result.
This is a visual representation of what's happening on the server side, so there's no fancy rendering or effects ( those will be added to the client later on ). Each star system is represented as a colored dot similar to stars in reality: hot blue stars ( O class ), Sun-type stars ( G class ), red dwarves ( K & M ), etc..
The model is generated procedurally on the fly in real time as the player moves. It's based on an octree.
Procedural generation does NOT mean that everything is random, in fact quite the contrary: if you come back at the same coordinates, you will exactly see the same stars !
