Here's the accompanying SVG markup:
For this example, we'll create a Sushi X Top animation that showcases the library's capabilities. The animation features a sushi roll rotating and scaling, with toppings (represented by small circles) moving in sync with the roll. fe expression script sushi x top
The FEExpression class takes two arguments: the element(s) to animate and an object containing the animation expressions. The expressions are functions that take a single argument, t , which represents the animation time. Here's the accompanying SVG markup: For this example,
<svg viewBox="0 0 200 200"> <g id="sushi-roll"> <rect x="50" y="50" width="100" height="100" fill="#FFC700" rx="20" /> <path d="M 100 50 L 150 100 L 100 150 Z" fill="#FFC700" /> </g> <g> <circle class="topping" cx="80" cy="80" r="10" fill="#FF69B4" /> <circle class="topping" cx="120" cy="80" r="10" fill="#FF69B4" /> <circle class="topping" cx="100" cy="120" r="10" fill="#FF69B4" /> </g> </svg> The expressions are functions that take a single
// Create a GUI to control the animation const gui = new GUI(); gui.add(animation, 'speed', 0.1, 10); gui.add(toppingAnimation, 'speed', 0.1, 10);
// Define the sushi roll and toppings const sushiRoll = svg.querySelector('#sushi-roll'); const toppings = svg.querySelectorAll('.topping');
