What is Three.js?

Three.js is a JavaScript library focused on 3D graphics that is designed to be lightweight, easy to use, and compatible with various web browsers. The main aim of this library is to create a flexible tool for developers, making the generation of 3D content on the web more accessible. At present, it features a WebGL renderer, and it also presents experimental options like WebGPU, SVG, and CSS3D renderers in its examples. To visualize scenes with Three.js, users must establish three critical components: a scene, a camera, and a renderer, which collectively allow viewing the scene from the camera's viewpoint. In addition to the WebGLRenderer, Three.js offers alternative renderers suitable for users with outdated browsers or those who do not support WebGL. To ensure that the visuals remain animated and fluid, it’s necessary to create an animation loop that refreshes the scene's rendering each time the display updates, typically at a frequency of 60 frames per second. Within this loop, developers can also call functions that modify or reposition elements in the scene dynamically while the application is active, enhancing interactivity. This configuration ultimately provides users with a seamless and engaging 3D experience while interacting with the application, inviting them to explore the content more thoroughly.
