Hi.
I´d like to draw a smooth spiral.
It looks a bit uneven, if I draw it with lines or ellipses, like here for example http://www.learningprocessing.com/exercises/chapter-13/exercise-13-5/ . I need thin lines.

So in my code I did sth. like this: (not perfectly done, only for testing)

 float numofCircles = 1;
PVector middleVec = new PVector(30,0);
float radius = 50
 
 
  float totalRadian = numofCircles * PI * 2;
  float startRadian = -PI;
  float currentRadian = startRadian;
 
  float targetX;
  float targetY;

//spiral starts from outside
 while (currentRadian < totalRadian)
  {
   
    currentRadian += PI/200;
    radius -=.05;
   
    targetX = cos(currentRadian) * radius + middleVec.x;
    targetY = sin(currentRadian) * radius + middleVec.y;
    treeGraphic.ellipse(targetX, targetY, 3, 3);
}


I think with bezier, you would get smoother curves, but not that easy.
Any idea?

Thanks, Martin
