Telefonbild

inspired by the idea of the "Telefonbilder" by Moholy-Nagy. See also under the "for humans" section.

  // big black vertical rectangle on the left
  fill(46,41,37);

  // black rectangle

Sweater Pattern

Result

Algorithm

/*
Nested for loops practice
using: 
 - beginShape()
 - endshape()
 - strokeWeight(15.0) -> for thick fat lines
 - strokeJoin(MITER); -> for edgy line connections :)
 
this should be a reproduction of pattern on one of my sweaters
(-> See Picture on the left) but without the mirroring.
 
*/

int elementsPerSide = 10;
int gap = 50;

graue brühe

this is a test algorithm for my project work. i want to visualize how algorithm affects our decicions. Like when following through youtube similar videos. In the end everything gets more and more alike.

Technically speaking its an ArrayList of Objects moving around. Added at mouseClicked() event. To get nice random grey tones i played around with colorMode(HSB) and the values of the color object.

v1: everything gehts grey..

Result

Algorithm

ArrayList<Brush> brushes; 

void setup() {
  size(600,600);
  background(255);
  
  colorMode(HSB);
  brushes = new ArrayList<Brush>();
  
}

void draw() {
   
  for (Brush brush : brushes) {
    brush.paint();
  }
}

void mouseClicked() {
  brushes.add(new Brush());
}

class Brush {
  float angle;
  int components[];
  float x, y;
  color clr;

  Brush() {
    angle = random(TWO_PI);
    x = mouseX;
    y = mouseY;
    clr = color(0, 0, random(100), 5);
    components = new int[4];
    for (int i = 0; i < 4; i++) {
      components[i] = int(random(1, 4));
    }
  }

  void paint() {
    float a = 0;
    float r = 0;
    float x1 = x;
    float y1 = y;
    float u = random(0.5, 1);
    

    fill(clr);
    noStroke();    
    
    ellipse(x, y, random(50,150), random(50,150));

    if (x < 0 || x > width ||y < 0 || y > height) {
      angle += HALF_PI;
    }

    x += 3 * cos(angle);
    y += 3 * sin(angle); 
    angle += random(-0.15, 0.15);
  }
}

v2: this version is more dreamy/friendly. It's a nice effect, but i don't think i will be following through this route.

Result

Algorithm

ArrayList<Brush> brushes; 

void setup() {
  size(600,600);
  background(255);
  
  colorMode(HSB);
  brushes = new ArrayList<Brush>();
  
}

void draw() {
   
  for (Brush brush : brushes) {
    brush.paint();
  }
}

void mouseClicked() {
  brushes.add(new Brush());
}

class Brush {
  float angle;
  int components[];
  float x, y;
  color clr;

  Brush() {
    angle = random(TWO_PI);
    x = mouseX;
    y = mouseY;
    clr = color(random(255), 0, random(255), 5);
    components = new int[4];
    for (int i = 0; i < 4; i++) {
      components[i] = int(random(1, 4));
    }
  }

  void paint() {
    float a = 0;
    float r = 0;
    float x1 = x;
    float y1 = y;
    float u = random(0.5, 1);
    

    fill(clr);
    noStroke();    
    
    ellipse(x, y, random(50,250), random(50,250));

    if (x < 0 || x > width ||y < 0 || y > height) {
      angle += HALF_PI;
    }

    x += 3 * cos(angle);
    y += 3 * sin(angle); 
    angle += random(-0.15, 0.15);
  }
