I like your stars very much and the general idea how they should scale. Size of stars is issue of zoom level/how close the stars are each another. Your shot has ~right size for the stars in that zoom level, but still I want to be able to zoom really close to see the star to shimmer in 128x128
I agree. Like I said, they only look good at around a medium zoom level, but kinda loose their luster when zoomed out far or zoomed in close. I think working out some celestia-style scaling would be the best solution.
Also, about black holes. Something I discovered, by mistake actually, is that adding some black around the edges makes kind of a cool effect, because background stars will seem to dissapear as they get close to the hole. Unfortunately you kinda loose the effect when you get one in a nebula and there's all this black around it, but I was thinking...anybody remember that screensaver you could have, I think it was Windows 98, where it would make this glass ball bounce around your screen and distort your icons and wallpaper like a lense? Wouldn't it be cool if that effect could somehow be applied to black holes?
