For this week’s assignment, I’ve used Pointillism tutorial. by Daniel Shiffman. It somehow reminded me of Vincent Van Gogh’s paintings, so for my image manipulation I chose his famous “Starry Night”.
Here’s the code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 |
PImage painting; //PImage brush; //PImage head; float x, y; float rot; int pointillize = 12; void setup() { size(500, 400); painting = loadImage("vincent.jpg"); //brush = loadImage("brush.png"); //head = loadImage("gogh.png"); //x = 0.0; //y = width/2.0; //rot = 0.0; background(255); smooth(); } void draw() { // Pick a random point int x = int(random(painting.width)); int y = int(random(painting.height)); int loc = x + y*painting.width; // Look up the RGB color in the source image loadPixels(); float r = red(painting.pixels[loc]); float g = green(painting.pixels[loc]); float b = blue(painting.pixels[loc]); noStroke(); // Back to shapes! Instead of setting a pixel, we use the color // from a pixel to draw a circle. fill(r, g, b, 100); ellipse(x, y, pointillize, pointillize); //image(brush, mouseX, mouseY, 50, 50); // painter's brush // translate(x, y); // rotate(rot); // imageMode(CENTER); // image(head, 0, 0); // x += 1.0; // rot += 0.02; // if (x > width+head.width) { // x = -head.width; // } } |
(I have some stuff commented out there that I’ve also tried to do using Shiffman’s tutorials)
The first one has the pointillize value 12, and the second one is 20.
