Babylon.js

Babylon.js is an open-source, WebGL-based 3D engine for building interactive graphics, games, and visualizations directly in the browser. It provides a comprehensive JavaScript/TypeScript API for creating, rendering, and managing 3D scenes, with support for complex meshes, materials, lighting, cameras, animations, and physics. The engine includes a robust physically based rendering (PBR) system, enabling realistic materials, reflections, shadows, and post-processing effects suitable for high-quality visual experiences.

Babylon.js offers an integrated node-based material editor, particle systems, skeletal animation, and support for major 3D asset formats such as glTF, OBJ, and STL. Developers can use the visual scene inspector to debug and tune scenes in real time, inspect draw calls, optimize performance, and adjust material or lighting settings without leaving the browser. The framework supports WebXR for VR and AR experiences, making it suitable for immersive applications.
