SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you add reliable user interaction to Three.js scenes so clicks, taps, drags, and keyboard input feel natural instead of brittle.

Core Features & Use Cases

  • Raycasting and selection: Detect which 3D object a user is pointing at and trigger contextual actions.
  • Camera and navigation controls: Configure orbit, fly, first-person, pointer-lock, and map-style controls for different experiences.
  • Touch, hover, drag, and keyboard input: Support desktop and mobile interaction patterns in games, configurators, editors, and immersive visualizations.
  • Use case: Build an interactive product viewer where hovering highlights parts, clicking selects meshes, and orbit controls are disabled while objects are being dragged.

Quick Start

Ask for a Three.js interaction implementation that adds raycasting, selection, and responsive camera controls to your scene.

Frequently Asked Questions about threejs-interaction

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I implement raycasting and object selection in a Three.js scene?▼

Raycasting in Three.js converts pointer coordinates to 3D rays, intersecting meshes to detect object selection. This Skill implements coordinate conversion and event-driven filtering to trigger contextual actions on selected objects.

How do I add touch input and drag controls to a Three.js browser scene?▼

Touch input in Three.js requires mapping touch events to camera controls and object interactions. This Skill supports mobile drag and tap patterns by managing control states and applying coordinate conversion for responsive behavior.

Does Three.js support both orbit controls and object dragging at the same time?▼

Three.js can disable orbit controls while objects are being dragged. This Skill manages event-driven control states, allowing interactive viewers where hovering highlights parts and dragging meshes suspends camera navigation.

What is the best way to handle keyboard input and camera controls in Three.js?▼

Handling keyboard input and camera controls in Three.js involves configuring orbit, fly, or first-person navigation. This Skill applies event-driven control state management to ensure responsive scene behavior across desktop and mobile patterns.

Why does my Three.js object selection feel brittle when clicking 3D meshes?▼

Brittle Three.js selection stems from imprecise coordinate conversion and missing object filtering during raycasting. This Skill implements reliable interaction logic for mouse, touch, drag, and hover input so clicks feel natural.
