How To Create And Animate Svg Polygons In 2023

In the field of web development, Scalable Vector Graphics (SVG) have become the go-to choice for developers looking to add some visual flair to their sites. SVG is a vector-based image format that can be used to create images that are infinitely scalable and can be used on any device. SVG polygons are one way to create complex shapes with SVG that can be used to create animations, designs, and more.

SVG polygons are shapes that are composed of multiple lines to form a single shape. They can be used for a variety of purposes, from adding a unique shape to your website to creating an animation. In this article, we’ll discuss how to create and animate SVG polygons in 2023.

What is an SVG Polygon?

An SVG polygon is a shape composed of multiple straight lines. It is an SVG element that can be used to create a variety of shapes, including stars, hexagons, and more. SVG polygons can be used to create custom shapes, or to animate existing shapes.

The advantage of using SVG polygons is that they are infinitely scalable, meaning they can be resized without losing any quality. This makes them ideal for use on any device, regardless of the size of the screen. Another advantage of SVG polygons is that they can be animated using JavaScript or CSS, allowing for some truly unique designs.

How to Create an SVG Polygon

Creating an SVG polygon is relatively simple. All you need to do is use the polygon element in your SVG code. This element will allow you to define the points of the polygon, as well as the style of the polygon. Here is an example of a basic SVG polygon:

The points attribute is used to define the points of the polygon. The points are defined by x and y coordinates, separated by a comma. In this example, the polygon is a triangle with points at (20,0), (40,0), (60,15), (40,30), (20,30), and (0,15). The style attribute is used to define the style of the polygon, such as the fill color, stroke color, and stroke width.

How to Animate an SVG Polygon

Once you have created an SVG polygon, you can animate it using JavaScript or CSS. Using JavaScript, you can use the setInterval() method to call a function that updates the polygon’s points. This can be used to move the polygon, rotate it, or resize it. Here is an example of a JavaScript function that rotates an SVG polygon:

function rotatePolygon(angle) {
 var points = polygon.getAttribute('points');
 
 var pointsArray = points.split(',');
 
 for (var i = 0; i < pointsArray.length; i++) {
 var x = pointsArray[i].split(' ')[0];
 var y = pointsArray[i].split(' ')[1];
 var newX = x * Math.cos(angle) - y * Math.sin(angle);
 var newY = x * Math.sin(angle) + y * Math.cos(angle);
 pointsArray[i] = newX + ' ' + newY;
 }
 
 var newPoints = pointsArray.join(',');
 
 polygon.setAttribute('points', newPoints);
 }

This function takes an angle (in radians) and rotates the polygon by that amount. You can use setInterval() to call this function at regular intervals to create an animation. Keep in mind that you will need to use browser prefixes for certain browsers.

Another way to animate an SVG polygon is to use CSS. CSS animations can be used to move, rotate, and resize an SVG polygon. Here is an example of a CSS animation for an SVG polygon:

#polygon {
 animation: movePolygon 5s linear infinite;
 }
 
 @keyframes movePolygon {
 from {
 transform: translate(0px, 0px);
 }
 to {
 transform: translate(100px, 100px);
 }
 }

This animation will move the SVG polygon from (0,0) to (100,100) over the course of 5 seconds. You can use other CSS properties, such as rotate and scale, to create other types of animations.

Conclusion

SVG polygons are a powerful tool for creating complex shapes and animations. They are infinitely scalable, making them ideal for use on any device.
