Three.js is a library for 3D graphics in JavaScript designed to be lightweight, user-friendly, and compatible across different web browsers. The primary goal of this project is to provide a versatile 3D library that simplifies the process of creating 3D content on the web. Currently, the library offers a WebGL renderer, though examples also showcase experimental WebGPU, SVG, and CSS3D renderers. To render visuals using Three.js, you'll need to set up three essential components: a scene, a camera, and a renderer, which work together to display the scene through the camera's perspective. Besides the WebGLRenderer, Three.js includes additional renderers that serve as alternatives for users with older browsers or those lacking WebGL capability. To keep the visuals animated and responsive, you should implement a loop that refreshes the scene rendering each time the screen updates, generally at a rate of 60 frames per second. Within this animation loop, you can also invoke other functions to alter or move elements in the scene dynamically while the application is running. This setup allows for a fluid and interactive 3D experience for users engaging with your application.
