Script Preparation code:


function generateNoise(width, height) {
    // Iterate from Top-Left to Bottom-Right
    let noise = [];
    for (let y = 0; y < height; y++) {
        for (let x = 0; x < width; x++) {
            if (noise[x] == null) noise[x] = [];
            noise[x][y] = Math.random();
        }
    } return noise;
}


function generateNoiseSingle(width, height) {
    // Iterate from Top-Left to Bottom-Right
    let noise = [];
    for (let y = 0; y < height; y++) {
        for (let x = 0; x < width; x++) {
            noise[xyToSingle(width, x, y)] = Math.random();
        }
    } return noise;
}

    return (y * width) + x;
