SWARM [Attractor to Line]

Use the code we did already

Spline3D sp2; void setup(){ ……………

Set up the points

sp2 = new Spline3D(); for(int i=0; i<20; i++){ Vec3D v = new Vec3D(-300+(600/20*i), random(-50,50), random(-50,50)+100); sp2.add(v); } .............................. } void draw(){ background(205); buildBox(DIMX, DIMY,DIMZ); if (controlP5.window(this).isMouseOver()) { cam.setActive(false); } else { cam.setActive(true); }

for(int i= 1; i<sp2.pointList.size(); i++){ Vec3D a = sp2.pointList.get(i); Vec3D b = sp2.pointList.get(i-1); stroke(0,90); line(a.x,a.y,a.z,b.x,b.y,b.z); } for(Ple_Agent pa : boids){ pa.flock(boids, 80,40,30, coh,ali,sep); pa.setMaxspeed(maxSpeed); pa.wrapSpace(DIMZ/2, DIMY/2, DIMZ/2); …………………… ………………………………………………………… gui(); }

Draw the line

A PLAN A SWARM A LINE

Follow the step to let the swarm follow the line

void draw(){ background(205); buildBox(DIMX, DIMY,DIMZ); if (controlP5.window(this).isMouseOver()) { cam.setActive(false); } else { cam.setActive(true); } for(int i= 1; i<sp2.pointList.size(); i++){ Vec3D a = sp2.pointList.get(i); Vec3D b = sp2.pointList.get(i-1); stroke(0,90); line(a.x,a.y,a.z,b.x,b.y,b.z); } for(Ple_Agent pa : boids){ pa.flock(boids, 80,40,30, coh,ali,sep); pa.setMaxspeed(maxSpeed); pa.wrapSpace(DIMZ/2, DIMY/2, DIMZ/2); …………………….…… …………….. …………

float m = map(mouseX,0,width,-5,5); Vec3D fLoc = pa.futureLoc(5); Vec3D cns = pa.closestNormalandDirectionToSpline(sp2,fLoc,m); pa.seek(cns,5); } gui(); }

Put it Back into 2D

Spline3D sp2; void setup(){ ……………

Make this to “0”

sp2 = new Spline3D(); for(int i=0; i<20; i++){ Vec3D v = new Vec3D(-300+(600/20*i), random(-50,50), 0 ); sp2.add(v); } .............................. } void draw(){ background(205); buildBox(DIMX, DIMY,DIMZ); if (controlP5.window(this).isMouseOver()) { cam.setActive(false); } else { cam.setActive(true); } for(int i= 1; i<sp2.pointList.size(); i++){ Vec3D a = sp2.pointList.get(i); Vec3D b = sp2.pointList.get(i-1); stroke(0,90); line(a.x,a.y,a.z,b.x,b.y,b.z); } for(Ple_Agent pa : boids){ pa.flock(boids, 80,40,30, coh,ali,sep); pa.setMaxspeed(maxSpeed); pa.wrapSpace(DIMZ/2, DIMY/2, DIMZ/2); …………………… ………………………………………………………… gui(); }

Put the starting point randomly

Spline3D sp2;

Just that simple

void setup(){ …………… for(int i=0; i<pop; i++){ Vec3D v = new Vec3D(random(-300,300),random(-300,300),random(-300,300)); Ple_Agent pa = new Ple_Agent(this, v); Vec3D initialVelocity = new Vec3D (random(-1, 1), random(-1, 1), random(-1,1)); pa.setVelocity(initialVelocity); pa.initTail(50); boids.add(pa); } .............................. }

Now I want to put the starting points to the 2 sides of the boundary

Spline3D sp2; void setup(){ …………… vall = new ArrayList(); for(int i=0; i<=pop; i++){ Vec3D v1 = new Vec3D(-300+2*(600/pop)*i,300,0); vall.add(v1); } Separate else{ Vec3D v2 = new Vec3D(-900+2*(600/pop)*i,-300,0); vall.add(v2); } Vec3D v = new Vec3D(random(-300,300),random(-300,300),random(-300,300)); Vec3D v0 = (Vec3D)vall.get(i); Ple_Agent pa = new Ple_Agent(this, v0); Vec3D initialVelocity = new Vec3D (random(-1, 1), random(-1, 1), random(-1,1)); pa.setVelocity(initialVelocity); pa.initTail(50); boids.add(pa);

} void draw(){ background(205); buildBox(DIMX, DIMY,DIMZ); if (controlP5.window(this).isMouseOver()) { cam.setActive(false); } else { cam.setActive(true); } ………………….. …………….. ………………………………………………………… gui(); }

the starting points

Turn the trail on

Move the line back to 3D

Make 2 lines for Attractors

Just did it Twice!

Spline3D sp2; Spline3D sp3; void setup(){ …………… sp2 = new Spline3D(); sp3 = new Spline3D(); for(int i=0; i<20; i++){ Vec3D v = new Vec3D(-300+(600/20*i), random(-50,50), random(50,50)+100); sp2.add(v); } for(int i=0; i<20; i++){ Vec3D v = new Vec3D(-900+(600/20*i), 200+random(-50,50), random(-50,50)+100); sp3.add(v); } .............................. }
