其实我是根据gh代码改的
ArrayList L=new ArrayList ();
//PeasyCam cam;
int total=400;
float x[]=new float[total];
OnCircle c1;
OnCircle c2;
PFont font;
public void setup() {
//
// cam = new PeasyCam(this, 200);
// cam.setMinimumDistance(50);
//cam.setMaximumDistance(5000);
size(600,400);
noLoop();
ellipseMode(CENTER);
background(255);
font= createFont("FFScala", 10);
textFont(font);
for(int i=0;i3){x[i]= random(15,30);}
else {x[i]= random(8,14);}
}
c1=new OnCircle(new On3dPoint(width/2,height/2,0), x[0]);
c2=new OnCircle(new On3dPoint(x[1]+width/2 + x[0],height/2,0), x[1]);
L.add(c1);L.add(c2);
line(c1.Center.x,c1.Center.y,c2.Center.x,c2.Center.y);
///*
for(int i=2;i=0;j-=1){
if (L.get(j).Center.DistanceTo(c3.Center)*1.02 < (L.get(j).radius + c3.radius)){
c1 =(OnCircle)L.get(j);
sign = false;
break;
}
}
count += 1;
} while(count<20 && sign == false);
if (sign){
L.add(c3);
line(c3.Center.x,c3.Center.y,c2.Center.x,c2.Center.y);
c2 = c3 ;
line(c1.Center.x,c1.Center.y,c2.Center.x,c2.Center.y);
}
}
//*/
}
public OnCircle circle(OnCircle c1, OnCircle c2, float r ) {
float l1 = c1.Center.DistanceTo(c2.Center);
float l2 = c1.radius + r;
float l3 = c2.radius + r;
float n = (float) Math.acos((l1 *l1 + l2 *l2 - l3 *l3) / (2 * l1 * l2));
On3dVector v =new On3dVector(c2.Center.x - c1.Center.x, c2.Center.y - c1.Center.y, c2.Center.z - c1.Center.z);
v.Rotate(n, new On3dVector(0, 0, 1));

v .mul(l2);
On3dPoint p =new On3dPoint(c1.Center.x + v.x, c1.Center.y + v.y, c1.Center.z + v.z);
return new OnCircle(p, r);
}
public void draw(){
for(int i=0;i |
