    Create animation loops with noise and GIF exports in one line of code. This library is a lightweight wrapper of createLoop.

    Features include:

    • GIF image rendering
    • noise loops



    <script src=""></script>
    <script src=""></script>


    function setup() {
        createCanvas(400, 400)
        createLoop({duration:3, gif:true})
    function draw() {
        translate(width / 2, height / 2)
        const radius = height / 3
        const x = cos(animLoop.theta) * radius
        const y = sin(animLoop.theta) * radius
        ellipse(x, y, 50, 50)


    Noise Loop

    • makes use of animLoop.noise()

    Noise Loop 2x

    • two noise seeds, one for x and one for y

    Noise Loop 1D

    • a noise value for each x position

    Noise Loop 2D

    • a noise value for each x and y position

    also works in instance mode


    When a sketch is initialized the following are attatched to it:

    • createLoop()
      • a function to be called in setup()
    • animLoop
      • an object containing helpful properties and methods for draw()


    This function can be called in three ways:

    createLoop() //defaults to three second duration

    createLoop options

    Name Default Description
    duration 3 sets the duration in seconds of the loop.
    framesPerSecond 30 approximate fps of the loop. This is the same as calling frameRate()
    noise options See noise options
    gif false can also accept true or options to be passed to GIF module. See gif options

    Options can be passed as an object:


    or as camelCase:


    noise options

    These can be passed in createLoop and also overridden each time animLoop.noise() is called. See this Coding Train explanation of how noise loops work.

    Name Default Description
    radius 1 radius of the circle in a noise field to query. Similar to the concept of frequency
    seed random(0,99999) noise field offset
    theta animLoop.theta By defalt is angular progress of the loop. This can be set in animLoop.noise() but not in createLoop

    gif options

    some notes on making GIF images:

    • The built in p5 frameRate() function will also set the delay between GIF frames
    • The GIF encoder gif.js uses web workers to render the GIF asynchronously
    Name Default Description
    render true render the GIF image alongside the sketch. Clicking on the image will begin downloading the GIF
    open false open the gif image in a new tab or window
    download false download the gif automatically
    fileName image.gif name of the downloaded GIF file
    startLoop 0 loop index to begin recording the GIF
    endLoop 1 loop index to end recording the GIF
    canvas <canvas> the canvas to render. By default this is the sketch canvas
    options {} options to pass to gif.js encoder. see gif.js documentation


    Because the aim here is to get loopin asap, this object provides some valuable properties and methods for animating loops. See documentation on Loop Instance for further details.

    Name Description
    progress linear progress of the loop with a range of 0 to 1
    theta angular progress of the loop in radians with range 0 to TWO_PI
    noise(options) returns a noise value between -1 and 1. See noise options
    noise1D(x,options) Same as above also accepting an x value, providing a 1D line of noise for each frame
    noise2D(x,y,options) Same as above also accepting a y value, providing a 2D plane of noise
    noiseSeed() set the noise seed. See noise options
    noiseRadius() set the noise radius. See noise options

    To do

    • add easing functions
    • set GIF size to reflect pixel density
    • add draw option to stay in sync with GIF loop
