Hello all. I'm trying to create an owl, and I'm wanting him to change size according to the Perlin noise function. Below is my code:

Code:

Owl owl;
Owl owl2;
Owl owl3;

float timeowl=0;
float incrementowl=.01;

void setup() {
  size(800,600,P3D);
  smooth();

  owl = new Owl(100);
  owl2 = new Owl(500);
  owl3 = new Owl(700);
}

void draw() {
  background(255);
  owl.display();
  owl2.display();
  owl3.display();
}
 

Class:

Code:

class Owl {
  float xpos;
  
  Owl(float xpos_) {
    xpos=xpos_;
  }
  
  void display() {
    fill(125);
    
    float n = noise(timeowl)*incrementowl;
    timeowl+=incrementowl;
    
    ellipse(xpos,250,60,60); //Owl head
    
    beginShape(TRIANGLES); //Owl ear
    vertex(xpos-15,230,0);
    vertex(xpos-5,230,0);
    vertex(xpos-10,200,0);
    endShape();
    
    beginShape(TRIANGLES); //Other owl ear
    vertex(xpos+15,230,0);
    vertex(xpos+5,230,0);
    vertex(xpos+10,200,0);
    endShape();
    
    fill(255,255,0); //Owl eyes
    ellipse(xpos-5,240,n,n);
    ellipse(xpos+5,240,n,n);
    
    fill(0); //Owl mouth
    ellipse(xpos,260,n,n);
  }
}

 

For some reason, my owl's eyes and mouth are staying the same shape, instead of changing based on the value of noise. I used Shiffman's idea of putting a println in there - I put println(n); and was getting values below 1 back, so I'm assuming there's nothing wrong there.

Also, how do I go about applying my Perlin noise to my owl's ears?

Thanks!  

Thanks! I was looking really closely, I didn't even think a pixel would escape my eyes. But I suppose it did
