So I created a universe with 10,000,000 stars today...
mygoditsfullofstars 2001 space odyssey RAM memory overload slow
Looking at the stats it took up approximately 12 gigabytes of RAM. I can probably optimize that later a little bit. Not to mention the fact that probably only 1/100,000 of that was on screen at any one time (draw distance was set to about 10,000km), so some sort of off-loading to disk would be best too. Maybe I'll work on that next, I've never done compression before - could be interesting. Anybody out there know any good articles on compression techniques?
Might publish a proper journal entry tomorrow about the gravitation system and the octree, if I have time. I'm also meant to be going to a ball with my girlfriend.
