Three.js

Definition

three.js is a JavaScript library that simplifies the creation of 3D graphics for the web. It provides an easy-to-use interface for rendering 3D scenes using WebGL, enabling developers to create complex animations and interactive visualizations without needing to dive deep into the low-level details of WebGL programming. The library supports various features such as lighting, shadows, and materials, making it a popular choice for artists and developers working in generative art.

5 Must Know Facts For Your Next Test

1. three.js abstracts away many complexities of WebGL, allowing artists to focus more on creativity rather than coding intricacies.
2. The library supports a wide range of 3D object formats, making it easier to import models created in other 3D design software.
3. three.js is frequently updated and maintained by a large community, ensuring compatibility with modern browsers and the latest web standards.
4. Animations in three.js can be easily created using built-in functions, allowing for smooth transitions and dynamic scene changes.
5. The library encourages interactivity, enabling users to manipulate 3D objects through mouse events and other user inputs.
