WebGL Distortion Hover Effects

Today we’d like to share a little hover effect library with you. The effect goes as follows: when hovering an image, we’ll use a displacement image to transition to another image. Using different displacement images, we can create a variety of looks. The main idea behind this little library is to recreate an effect similar to what we have done previously, but with broader support, better performance and that is easier to customize.

The demo is kindly sponsored by HelloSign API: Everything IT requires and Developers love. If you would like to sponsor one of our demos, find out more here.

The animation is based on WebGL and we use three.js, so it works in all recent browsers.

To get started we need two main images and one displacement image to create the effect.

Here is an example displacement image we’re using:


The effect works in the following three steps:

  1. Modifying the images with the displacement image
  2. A classic fade between the 2 images
  3. Reverse the displacement


We can use a simple div to initiate our effect:

var myAnimation = new hoverEffect({
	parent: document.querySelector('.my-div'),
	image1: 'images/myImage1.jpg',
	image2: 'images/myImage2.jpg',
	displacementImage: 'images/myDistortionImage.png'

Keep in mind that the demo needs to run in a server environment.

We hope you like this library and find it useful!
