Typo Portraits

pointillism portraits

cubist portrait

Question:
 How to generate "typo portraits"?

self portrait in particles




Example 1:

PImage img;
int smallPoint, largePoint;
PFont f;
float threshold = 80;

void setup() {
size(736, 736);
img = loadImage("portrait.jpg");
smallPoint = 2;
largePoint = 30;
imageMode(CENTER);
noStroke();
background(255);

// Create the font
printArray(PFont.list());
f = createFont("Georgia", 9);
textFont(f);
textAlign(CENTER, CENTER);

}

void draw() {
float value;
color pix;
// if (mousePressed == true) {
background(80);
int counter = 0;
char letter;

float pointillize = map(mouseX, 0, width, smallPoint, largePoint);
float threshold = map(mouseY, 0, height, 0, 255);
for (int x = 0; x < img.width; x+=pointillize) {
for (int y = 0; y < img.height; y+=pointillize){
pix = img.get(x, y);
value = brightness(pix);
if (value > threshold)
fill(0, 255, 0);
else fill(0);
//ellipse(x, y, 5, 5);
counter = int(random(66, 123));
letter = char (counter);
text(letter, x, y);


}
}
// }

}



Example 2:

/**
* Pointillism
* by Daniel Shiffman.
*
* Mouse horizontal location controls size of dots.
* Creates a simple pointillist effect using ellipses colored
* according to pixels in an image.
*/

// The next line is needed if running in JavaScript Mode with Processing.js
/* @pjs preload="moonwalk.jpg"; */

PImage img;
int smallPoint, largePoint;

void setup() {
size(736, 736);
img = loadImage("portrait.jpg");
smallPoint = 4;
largePoint = 40;
imageMode(CENTER);
noStroke();
background(255);
}

void draw() {
float pointillize = map(mouseX, 0, width, smallPoint, largePoint);
int x = int(random(img.width));
int y = int(random(img.height));
int xWidth = int(random(10, 200));
int yHeight = int(random(10, 200));
int xShift = int(random(-20, +20));
int yShift = int(random(-20, +20));
for (int i = 0; i< xWidth; i++) {
for (int j = 0; j< yHeight; j++) {
color pix = img.get(x+i, y+j);
stroke(pix);
 //ellipse(xShift+x+i, yShift+y+j, pointillize, pointillize);
point(xShift+x+i, yShift+y+j);
}
}
}


Example 3:

float resolution;
float radius = 100;
float circleX;
float circleY;
float circles;
float circleW;
float circleH;
float offset;
PImage img;


void setup() {
  size(736, 736);
  circleX = 0;
  circleY = 0;
  background(0);
  img = loadImage("portrait.jpg");
}

void draw() {
  float value;
  color pix;

  fill(0,0,0,25);
//  rect(0,0,width,height);
  translate(width/2, height/2);
  fill(255);
  noStroke();
  offset++;

  resolution = map(sin(offset*0.00025), -1, 1, 5, 50);
  //resolution = 50;
  circles = 200;

  circleW = map(sin(offset*0.05), -1, 1, 1, 10);
  circleH = map(sin(offset*0.05), -1, 1, 1, 10);

  for (int i = 0; i < resolution; i++) {

    float scale = 200;

    float waveAngle = map(i, 0, resolution, 0, TWO_PI * circles);
    float waveOffset = sin(waveAngle) * scale*1.2;  //scale the -1 to 1 up

    float angle = map(i, 0, resolution, 0, TWO_PI * 331); //multiply for weirdness

    float circleOffsetX = cos(angle) * (radius + waveOffset); //xposition
    float circleOffsetY = sin(angle) * (radius + waveOffset); //yposition

    float x = circleX + circleOffsetX;
    float y = circleY + circleOffsetY;

    pix = img.get(int(x+width/2), int(y+height/2));
    value = brightness(pix);
    fill(0, green(pix), blue(pix));
    ellipse(x, y, circleW, circleH);

  }

}


Final Project:
Self Portrait Demo:
最少三種
例如，Andy Warhol 風格，字型風格，拼貼風格，動態曼陀羅風格，...
