Build a star field animation from scratch in JavaScript and HTML5 canvas
Hi everyone! In this video, I'll show you how to build a beautiful star field animation from scratch using JavaScript and the HTML5 canvas.
We'll start by looking at the final result and the different types of stars we'll be creating, including simple round ones and more complex ones with diffraction spikes, similar to those seen in images from the James Web Space Telescope.
I’ll walk you through the math and code needed to draw these unique star shapes, highlighting how we use canvas transformations like translate and rotate to simplify the process.
Then, we will put it all together inside a Vue.js component, which allows for easy integration and real-time control over the animation's parameters. We'll use the requestAnimationFrame method to create a smooth, dynamic animation.
You'll see how to handle key features, such as changing the number of stars, adjusting their speed and size, and adding a glowing effect with configurable blur. The core logic can be adapted for any web project, whether you're using Vue.js, React, or just plain JavaScript.
