Clip-Path Circle Reveal Animation With Mouse Movement

Published at

12/3/2024

What’s the Plan?

We’ll create an animation where an image is revealed through a circle that moves with your mouse. You’ll also be able to tweak the size of the circle and experiment with the behavior.

Here’s what you’ll need:

GSAP: For buttery-smooth animations.
Tweakpane: For a slick UI to adjust the animation on the fly.
HTML & CSS: To set up and style the page.

body {

  height: 100vh;
  display: flex;
  justify-content: center;
  align-items: center;
  background: #000;
  overflow: hidden;
}

img {
  width: 100%;
  height: auto;
  clip-path: circle(var(--size, 10%) at var(--x, 50%) var(--y, 50%));
  transition: clip-path 0.6s;
}

JS

import gsap from "https://esm.sh/gsap";

// Smooth animations
const xTo = gsap.quickTo("img", "--x", { duration: 0.6, ease: "power3" });
const yTo = gsap.quickTo("img", "--y", { duration: 0.6, ease: "power3" });
const sizeTo = gsap.quickTo("img", "--size", { duration: 0.6, ease: "power3" });

// Update based on mouse movement
window.addEventListener("mousemove", (e) => {
  xTo((e.clientX / window.innerWidth) * 100);
  yTo((e.clientY / window.innerHeight) * 100);
});
