Working with Point Lights and Shadows in Three.js

Lighting is the key to depth and realism in 3D web graphics, but getting point lights to behave correctly can be challenging. This text-based course guides you through the foundational concepts of Three.js lighting, focusing on the versatile PointLight to create localized illumination and shadows. You will learn to: * Understand the core mechanics of PointLight and how it differs from ambient or directional lights * Configure essential light properties including color, intensity, distance, and decay * Set up shadow maps and adjust shadow bias to prevent common rendering artifacts * Position lights dynamically within a 3D scene using vector coordinates * Apply modern ES6 module imports and structure clean Three.js initialization code * Optimize shadow resolution for better performance on mobile and desktop web browsers You will start with basic terminology and scene setup, then progress to positioning lights, enabling shadows, and fine-tuning performance settings. This course is designed for beginners with basic HTML and JavaScript knowledge; no prior 3D graphics experience is required. Start lighting your Three.js scenes with precision today.
