starfield, cool algorithm to move stars.
Apr 13th, 2009, 7:04pm  
Hi,

to whoever is interested in a really cool algorithm to move the stars in a starfield, found this made by Jim Brown at http://mobile.processing.org/discourse/YaBB.cgi?board=games;action=display;num=1210073922

can anybody give me a hand to understand this algoritym,
in particular the spread number and the z number.

z-=SPEED;
   sx=(x*SPREAD)/(z)+CX;
   sy=(y*SPREAD)/(4+z)+CY;

to see the animation just copy paste this code from Jim into processing, just add the size() window. size(500,500,P3D);

thanks!
