Assignment 2- Shaikha AlKaabi

For this week’s assignment I wanted to create a feather-like magazine design. I got some inspiration from Peacock feathers since they are known for their iridescent colors and striking patterns, featuring an eye-like design.  While working on the code I wanted each “feather” to move whenever the mouse move over it so I used the sin function to scale the flutter effect. 

A code that I’m particularly happy about is the one that creates an ombre effect on the “feathers”:

let inter = map(i, 0, featherHeight, 0, 1);

let col = lerpColor(c1, c2, inter);

This code helps the colors to smoothly change from c1 and c2 creating the ombre effect.

let featherWidth = 100;
let featherHeight = 100;
let cols, rows;
let c1, c2;

function setup() {
  createCanvas(400, 400);
  cols = width / featherWidth; 
  rows = height / featherHeight * 2; 

}

function draw() {
  background(255);
  for (let i = 0; i <= cols; i++) {
    for (let j = 0; j <= rows; j++) {
      let x = i * featherWidth;
      let y = j * featherHeight / 2;

      // Adjusting for every other row to create a staggered effect so that the feathers dont overlap
      if (j % 2 === 0) {
        x += featherWidth / 2;
      }

      // Check if the mouse is over the current feather shape
      let mouseOver = dist(mouseX, mouseY, x, y) < featherWidth / 2;

      drawFeather(x, y, mouseOver);
    }
  }
}

function drawFeather(x, y, mouseOver) {
  if (mouseOver) {
    // Generate a gradient of colors for the ombre effect
    c1 = color(random(255), random(255), random(255), 100);
    c2 = color(random(255), random(255), random(255), 100);
  } else {
    c1 = color(0, 100);
    c2 = color(0, 100);
  }

  // Draw and color the feather with a diamond shape using QUAD_STRIP
  noFill();
  strokeWeight(1);
  beginShape(QUAD_STRIP);
  for (let i = 0; i <= featherHeight; i++) {
    let inter = map(i, 0, featherHeight, 0, 1);
    let col = lerpColor(c1, c2, inter);
    stroke(col);
    
    // Introduce fluttery motion when mouse is over
    let flutter = mouseOver ? sin(frameCount / 10 + i / 3) * 2 : 0; // Adjust flutter effect here
    let baseXOffset = sin(map(i, 0, featherHeight, 0, PI)) * featherWidth / 2;
    let xOffset = baseXOffset + flutter; // Apply flutter effect
    vertex(x - xOffset, y + i - featherHeight / 2);
    vertex(x + xOffset, y + i - featherHeight / 2);
  }
  endShape();
}

function mouseMoved() {
  redraw(); 
}
