To configure shadows in Three.js, you need to enable shadow maps on the renderer and set shadow-casting properties on lights and objects. This Skill guides you through configuring shadow behavior for AmbientLight, DirectionalLight, PointLight, SpotLight, and RectAreaLight.

Image-based lighting (IBL) in Three.js uses environment maps to achieve realistic lighting and reflections without manually placing multiple light sources. You need it when you want consistent, physically accurate illumination and tone mapping across complex 3D scenes.

You can set up a minimal Three.js scene by adding an AmbientLight and a DirectionalLight, then enabling shadows to observe immediate visual improvements. This Skill provides practical examples for common real-time rendering scene setups.

Your Three.js scene looks flat due to incorrect lighting configurations or missing environment lighting. This Skill solves inconsistent rendering by providing comprehensive guidance on light types, tone mapping, and image-based lighting (IBL) for realistic results.

Performance tips for real-time lighting in Three.js include using helper utilities to visualize light parameters and optimizing shadow configurations. This Skill offers practical examples and performance tips to maintain high frame rates during rendering.

Yes, Three.js supports RectAreaLight to simulate light emitted from rectangular surfaces. This Skill details the behavior of RectAreaLight alongside other light types like PointLight and SpotLight to achieve realistic illumination in your scenes.
