Detailed Guide

Read the detailed guide before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end-to-end work, read the guide completely.

When to Use

• You need user interaction inside a Three.js scene.
• The task involves raycasting, object picking, pointer handling, touch input, or camera controls.
• You are building an interactive 3D experience rather than a passive render.

Example

Add pointer selection to this canvas using its bounding rectangle, test after resize/scroll and provide keyboard selection. Dispose listeners/controls on unmount and verify picking nested meshes.
