Three.js
Three.js is a cross-browser JavaScript library and application programming interface (API) used to create and display animated 3D computer graphics in a web browser using WebGL. It simplifies the process of building 3D scenes, handling rendering, cameras, lights, materials, and geometries, making it accessible for developers without deep graphics programming expertise. It is widely used for interactive 3D visualizations, games, data visualizations, and virtual/augmented reality experiences on the web.
Developers should learn Three.js when building interactive 3D web applications, such as product configurators, architectural visualizations, educational simulations, or browser-based games, as it provides a high-level abstraction over WebGL, reducing complexity and development time. It is particularly valuable for projects requiring real-time 3D rendering without plugins, leveraging modern web standards for broad compatibility and performance. Use it to enhance user engagement with immersive visuals in marketing, e-commerce, or data analysis tools.
