For this assignment I chose to use a colorful picture of a high school friend.

Initially, I wanted the interaction to be like painting on a canvas; as the mouse drags, part of the image appears. However, I felt that given the small size of the squares that appear while “painting”, it would take too long to paint the entire image. Therefore, I added random squares that would simultaneously appear as mouse drags and paints.

At first, I also randomized the size of the squares, however the random larger squares were too large and not detailed enough to create the image.

Then, I changed the size of the dots to be consistently small and decided to add two more lines of squares that would appear to the upper right and lower left of the mouse as it dragged. I also sped up the appearance of the random dots.

function setup(){
    createCanvas(314, 480);
    background(255); //black background
    frameRate(500); //sped up the frame rate
}

var rSize = 3;

function draw(){
	noStroke(); //no outline
	fill(photo.get(mouseX, mouseY)); //fill of square is color of background photo
	var locX = random(0, width); //random x coordinate
	var locY = random(0, height); //random y coordinate
	rect(locX, locY, rSize, rSize); //draw square
}

function mousePressed(){
	fill(photo.get(mouseX, mouseY)); //fill of square is color of background photo
	rect(mouseX, mouseY, rSize, rSize); //square drawn when mouse is clicked
	fill(photo.get(mouseX - 50, mouseY + 50, mouseY)); //fill of square is color of background photo
	rect(mouseX - 50, mouseY + 50, rSize, rSize); //square drawn towards upper right 
	fill(photo.get(mouseX + 50, mouseY - 50)); //fill of square is color of background photo
	rect(mouseX + 50, mouseY - 50, rSize, rSize); //square drawn towards lower left

            ellipse(i, y, 2, 2);

                                                            // vertical lines of dots 
            var colorLocationV = underlyingImage.get(x, i); // gets color value of image at (x,i)

            fill(colorLocationV);                           // fills circles with color of image at (x,i)

var timer = 0;

function draw() {             // draw at a defined time (0, 6, 12, etc.)
   makeCorner(timer, timer);
   timer += 6;
}
 

Using the sample code given for this project as a starting point, I wanted to create more directionality & structure in how the points aggregated to create the underlying portrait. Starting at the top-left corner of the canvas, I wanted the pixels to aggregate horizontally until the edge of the canvas, then vertically (see sketch). I ended up writing a code which does all the horizontal and vertical pixels in each row simultaneously, however, through the variance in point sizes I was able to make the aggregate of the pixels more engaging and interesting and am overall content with the result.

var x = 230;
var y = 0;


function preload() {
    var portraitURL = "https://s1.postimg.org/1qix3ahu5r/IMG_6211.jpg";
    portrait = loadImage(portraitURL);
}

function setup() {
    createCanvas(230, 300);
    background(229,203,170);
    portrait.loadPixels();
    frameRate(60);

}

function draw() {
    //finding color
    var px = x;
    var py = y;
    var ix = constrain(floor(px), 0, width);
    var iy = constrain(floor(py), 0, height);
    var colorOfPoint = portrait.get(ix, iy);

    //generates waterfall effect
    push();
    y += 2.5;
    noStroke();
    fill(colorOfPoint);
    rect(x, y, 2, 2);
    pop();

    if (y > height) {
        x -= 2.5;
        y = 0;
    }
}

This is a portrait of my friend, Amara. At first, I really wanted to code a waterfall effect into the picture, but I was unsuccessful. Still, I spent a lot of time of this project and learned a lot, and I am pleased with the results.

After being inspired by Professor Golan’s work, I decided to approach this project by laying a grid of circles on the picture. The grid using the nested for loop will create a sense of geometric order of the display. I also find it interesting that I can play with the visibility of the content by adjusting the size of the circles. So I added the Mouse Pressed so that when pressed the circle will become larger, which will gradually shows a clearer version of the picture.
