A Chat with GPT-4: Palm Tree Collage

Using GPT-4 in ChatGPT to code is fun. This same example didn't really work in Processing (Java) but it worked without much fuss in p5.js. Really became acquainted with the model cutting code off halfway through and needing to prompt with 'keep going'. Demo at bottom of post. Picture from Dall-E.

use p5.js to take an image and split it into a collage with movable pieces (32)

GPT:

As an AI language model, I don't have the ability to create visual content using p5.js. However, I can provide you with the basic steps to create a collage with movable pieces using p5.js:

Note: This is just a basic outline of the steps involved in creating a collage with movable pieces using p5.js. The actual implementation may involve additional steps and modifications based on your specific requirements.

Bram:

write it in js

GPT:

Sure, here's an example code in JavaScript using p5.js library to create a collage with movable pieces:

let img; // variable to store the image
let smallCanvases = []; // array to store the small canvases
let selectedCanvas = null; // variable to store the currently selected canvas
let offsetX, offsetY; // variables to store the offset between mouse and canvas position

function preload() {
  img = loadImage('image.jpg'); // load the image
}

function setup() {
  createCanvas(800, 800); // create a canvas
  image(img, 0, 0, width, height); // display the entire image on the canvas
  for (let i = 0; i < 32; i++) {
    let smallCanvas = createGraphics(50, 50); // create a small canvas
    let x = random(width - smallCanvas.width); // set a random x position
    let y = random(height - smallCanvas.height); // set a random y position
    smallCanvas.image(img.get(x, y, smallCanvas.width, smallCanvas.height), 0, 0); // display the extracted pixels on the small canvas
    smallCanvases.push({
      canvas: smallCanvas,
      x: x,
      y: y,
      angle: 0,
      alpha: 150 // set the initial transparency to 150
    }); // add the small canvas to the array
  }
}

function draw() {
  background(255); // clear the canvas
  for (let i = 0; i < smallCanvases.length; i++) {
    let smallCanvas = smallCanvases[i];
    push(); // save the current transformation matrix
    translate(smallCanvas.x, smallCanvas.y); // move the small canvas to its position
    rotate(smallCanvas.angle); // rotate the small canvas
    blendMode(DARKEST); // set the blend mode to make the small canvas partially transparent
    tint(255, smallCanvas.alpha); // set the transparency of the small canvas
    image(smallCanvas.canvas, 0, 0); // display the small canvas
    pop(); // restore the previous transformation matrix
  }
}

function mousePressed() {
  for (let i = 0; i < smallCanvases.length; i++) {
    let smallCanvas = smallCanvases[i];
    if (mouseX >= smallCanvas.x && mouseX

Bram:

keep going

GPT:

Here's the rest of the code:

<= smallCanvas.x + smallCanvas.canvas.width &&
        mouseY >= smallCanvas.y && mouseY <= smallCanvas.y + smallCanvas.canvas.height) {
      selectedCanvas = smallCanvas; // set the selected canvas
      offsetX = mouseX - selectedCanvas.x; // calculate the offset between mouse and canvas position
      offsetY = mouseY - selectedCanvas.y;
      break; // exit the loop
    }
  }
}

function mouseReleased() {
  selectedCanvas = null; // reset the selected canvas
}

function mouseDragged() {
  if (selectedCanvas) {
    selectedCanvas.x = mouseX - offsetX; // update the position of the selected canvas
    selectedCanvas.y = mouseY - offsetY;
  }
}

function keyPressed() {
  if (keyCode === UP_ARROW && selectedCanvas) {
    selectedCanvas.angle -= PI / 8; // rotate the selected canvas counterclockwise
  } else if (keyCode === DOWN_ARROW && selectedCanvas) {
    selectedCanvas.angle += PI / 8; // rotate the selected canvas clockwise
  } else if (keyCode === LEFT_ARROW && selectedCanvas) {
    selectedCanvas.alpha -= 10; // decrease the transparency of the selected canvas
    selectedCanvas.alpha = constrain(selectedCanvas.alpha, 0, 255); // limit the transparency to the range [0, 255]
  } else if (keyCode === RIGHT_ARROW && selectedCanvas) {
    selectedCanvas.alpha += 10; // increase the transparency of the selected canvas
    selectedCanvas.alpha = constrain(selectedCanvas.alpha, 0, 255); // limit the transparency to the range [0, 255]
  }
}

This code creates an array of 32 small canvases, each containing a randomly extracted portion of the loaded image. The small canvases are displayed on the canvas with partial transparency and can be moved, rotated, and made more or less transparent using the mouse and keyboard. The currently selected canvas is stored in a variable and updated when clicked or dragged.

Bram:

start the collage with the complete image with the tiles only jittered away from their spot

GPT:

Sure, here's an updated version of the code that starts the collage with the complete image and jitters the tiles away from their original positions:

let img; // variable to store the image
let smallCanvases = []; // array to store the small canvases
let selectedCanvas = null; // variable to store the currently selected canvas
let offsetX, offsetY; // variables to store the offset between mouse and canvas position

function preload() {
  img = loadImage('image.jpg'); // load the image
}

function setup() {
  createCanvas(800, 800); // create a canvas
  image(img, 0, 0, width, height); // display the entire image on the canvas
  let tileSize = 50; // set the size of the tiles
  for (let y = 0; y < height; y += tileSize) {
    for (let x = 0; x < width; x += tileSize) {
      let smallCanvas = createGraphics(tileSize, tileSize); // create a small canvas
      let jitterX = random(-tileSize / 2, tileSize / 2); // set a random jitter in x direction
      let jitterY = random(-tileSize / 2, tileSize / 2); // set a random jitter in y direction
      smallCanvas.image(img.get(x + jitterX, y + jitterY, tileSize, tileSize), 0, 0); // display the extracted pixels on the small canvas
      smallCanvases.push({
        canvas: smallCanvas,
        x: x,
        y: y,
        angle: 0,
        alpha: 150 // set the initial transparency to 150
      }); // add the small canvas to the array
    }
  }
}

function draw() {
  background(255); // clear the canvas
  for (let i = 0; i < smallCanvases.length; i++) {
    let smallCanvas = smallCanvases[i];
    push(); // save the current transformation matrix
    translate(smallCanvas.x, smallCanvas.y); // move the small canvas to its position
    rotate(smallCanvas.angle); // rotate the small canvas
    blendMode(DARKEST); // set the blend mode to make the small canvas partially transparent
    tint(255, smallCanvas.alpha); // set the transparency of the small canvas
    image(smallCanvas.canvas, 0, 0); // display the small
