Three.js: Create and Display 3D Graphics on the Web Easily

What is Three.js?

Three.js is a popular JavaScript library used for creating and displaying 3D graphics on the web. It is built on top of WebGL, which is a low-level JavaScript API for rendering 3D graphics in a web browser. Three.js provides a more user-friendly interface for developers to create and manipulate 3D scenes and objects, without having to directly interact with the WebGL API. With Three.js, developers can easily create and animate 3D objects, add lighting and shadows, apply textures and materials, and even create complex scenes with multiple objects. Three.js also includes various helper classes and functions to simplify common tasks like camera movement, object positioning, and collision detection. Overall, Three.js is a powerful tool for creating stunning 3D visualizations and games on the web, and is widely used by developers and designers around the world.
