This guide provides a comprehensive overview of the core concepts of Three.js, the leading JavaScript library for WebGL 3D rendering. It covers setting up the entire 3D environment, including the Scene, Camera types (Perspective, Orthographic), and the WebGLRenderer. Users will learn to handle object hierarchies, apply transforms (position, rotation, scale), and manage complex rendering settings like lighting, shadows, and environment maps. Essential for any developer starting a WebGL project.

Configure Three.js scenes with PBR materials like MeshStandardMaterial, add various light types, enable shadows, and use environment maps for realistic reflections. Essential for fixing black or flat models and achieving physically based rendering.

Implement stable and scalable directional shadow systems for Three.js applications. This skill covers large procedural worlds, city scenes, and terrain rendering with moving cameras. It includes techniques like WebGPU/TSL shadow nodes, cascades, cached clipmaps, texel stabilization, update budgets, and targeted invalidation to ensure performance.

Implement high-quality volumetric cloud systems in Three.js using weather-driven density, bounded raymarching, and temporal reconstruction. Supports multiple layers, cloud shadows, and scalable quality modes for realistic weather visualization.
