The p5.sound library has a built-in FFT object, which comes in handy with a lot of useful methods depending on what you need to do. Then, using these different ranges, you can make your drawing respond differently for the bass, mid, or high frequencies of the signal. So after you run an FFT analysis on an audio track, you can get a detailed report of its complete frequency spectrum and the amplitude of each frequency range. What if you would want to create different animations for the bass frequencies and for the high ones, or use a custom range of frequencies to animate different parts of your drawing? Here is where a Fast Fourier Transform can broaden your options.Īt its heart FFT is an algorithm, that analyses a waveform and provides data about its different frequencies. This will give you the ability to animate your drawing, but only based on a single input. When you want to make a drawing respond to an audio signal, the most basic thing you could do is to make it respond to the overall signal’s volume, its amplitude.

We really hope this tutorial has been useful, and that you have found inspiration in these effects!Īnimated Fragment Slideshow was written by Luis Manuel and published on Codrops. Select the next slide: hide current items, update indexes, and show the new current item Ty: piece.h_ty 0 ? currentIndex - 1 : slidesLength - 1 Stop the pieces animation at 60%, and run a new indefinitely animation of `ty` for each piece ![]() Now we have all the options for each type of item, lets put them togheter to pass it to the Pieces library! // Build the array of items to draw using Pieces Finally, we need to make sure that the slider is responsive with a couple of media queries. But we also want them to fallback to their initial markup if no JavaScript is available. We’ll need to hide the images and texts as we’ll be redrawing them with our library. The slideshow needs some special styling for our effect. ![]() The markup is quite simple, since we have each slide with a corresponding image and text, the canvas element to animate things, and buttons to navigate through the slider. Let’s start! HTML Structureīefore starting to write Javascript code, let’s see how we have defined the HTML for our slider. Throughout the tutorial we will explain each piece of code, so you can learn how to implement your own animations using the Pieces library. To see all the possible options I recommend you check out the documentation on Github. But anyway, let’s quickly see some essential concepts to be able to start using this library.Īssuming that we want to draw and animate an image, these are the basic elements that make up the scene: Pieces Basic ElementsĪs you can see, the image we want to draw will be our item, which will be divided into several pieces, which can also vary in size and position according to the options we define. ![]() ![]() So, without further ado, let’s see how to use this library! Getting started with PiecesĪll the detailed documentation about the Pieces library can be found in its Github repository. To achieve the desired effects, I developed a library that I called “Pieces”, since it allows to draw and animate text, images and SVG paths through rectangular pieces. Since I saw it, I wanted to implement an effect like that for my new personal website, which I recently launched:. The source of inspiration for this kind of effect came from the Dribbble shot Shift Animation by Alexander Saunki: Shift Animation The demo is kindly sponsored by: Northwestern’s Online Master’s in Information Design and Strategy.
