Lorenz attractor trouble
Jun 3rd, 2005, 10:42am  
Hey guys, I was hoping some o you could help me with this stuff... I admit I'm no math wiz (at all), but I can't get this equation to render properly...

code:
void setup(){
 size(400,400);
 loop();
 background(255);
 stroke(0);
 strokeWeight(2);
}

float a=20.0, b=(8/3), c=10.0, d=0.0, T = 0.02;
float xP = random(-10, 10), yP = random(-10, 10), zP = random(-10, 10);
void draw(){
 translate(200,200);
 xP += ((a*d)*yP) - ((a*d)*xP);
 yP += (d*(b*xP)) - (d*yP) - (d*(zP*xP));
 zP += (d*(xP*yP)) - (d*(c*zP));
 d += T;
 point(xP,yP, zP);
}


I renders squat, except if I leave out zP in the point rendering... then all I get is a point in 0.0,0.0 exactly... I dunno if I screwd up the equation, or what the hell I did :)

change size(400,400); to size(400,400,P3D);

appeared some dots on my screen at least, without removing the zP..
