Hey!
I found this little Toxiclibs example but i can't get it to run.
the problem is, that it wants to convert a List<Vec2D> to an ArrayList and this is not possible.

i hope somebody can help me out here.

float   XRAD = 300;
float   YRAD = 500;
int     RES = 6;
int     NUM_POINTS=6;

 

void setup() {

  size(1024, 768);
  smooth();
  noLoop();

}

 

void draw() {

ColorTheme t = new ColorTheme("test");

t.addRange("fresh ivory", 0.5);
t.addRange("intense goldenrod", 0.25);
t.addRange("intense red", 0.15);
t.addRange("fresh teal", 0.05);
t.addRange("bright yellow", 0.05);

t.addRange(ColorRange.BRIGHT, TColor.newRandom(), random(0.02, 0.05));


ColorList list = t.getColors(160);

long timeStamp=System.currentTimeMillis()/1000;


beginRecord(PDF, "colors-"+timeStamp+".pdf");

background(list.getLightest().toARGB());
noStroke();
drawSpline(list);
endRecord();
}


void keyPressed() {

redraw();
}

 

void drawSpline(ColorList list) {

int numCols = list.size();


Vec2D[] points=new Vec2D[NUM_POINTS];

points[0]=new Vec2D(-XRAD,random(0.2,0.9)*height);

for(int i=1; i < points.length-1; i++) {

points[i]=new Vec2D(random(-1,1)*50+(float)i/points.length*width,random(0.25,0.75)*height);

}

points[points.length-1]=new Vec2D(width+XRAD,random(height));

ArrayList vertices = new Spline2D(points).computeVertices(width/RES);

for(Iterator i=vertices.iterator(); i.hasNext(); ) {

Vec2D v=(Vec2D)i.next();

fill(list.get(MathUtils.random(numCols)).toARGB());
ellipse(v.x,v.y,noise(v.y*0.01)*XRAD,noise(v.x*0.01)*YRAD);

}
}
