SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you turn passive Three.js scenes into interactive experiences by handling input, selection, camera control, and object manipulation without reinventing the interaction layer.

Core Features & Use Cases

Raycasting for click, hover, and touch-based object picking.
Camera controls including orbit, fly, first-person, pointer lock, trackball, and map navigation.
Selection and drag workflows for editors, configurators, data visualizations, and 3D dashboards.
Coordinate conversion and event management patterns that keep interactions responsive and maintainable.

Quick Start

Use the threejs-interaction skill to add orbit controls and raycast-based selection to a Three.js scene.

FAQPage Schema

How do I make Three.js objects clickable with mouse input?▼

To make Three.js objects clickable, use a Raycaster to cast rays from the camera through the mouse coordinates, detecting intersections with 3D meshes for object picking and click selection workflows.

What is the best way to add touch input and OrbitControls to a Three.js scene?▼

The best way to add touch input and camera controls is implementing OrbitControls, which handles multi-touch events for orbit, pan, and zoom navigation while maintaining responsive interaction across mobile devices.

Can I use raycasting for hover and drag selection in Three.js?▼

Yes, raycasting supports hover and drag selection in Three.js by continuously tracking pointer movement against scene objects, enabling interactive highlight states and selection helpers for 3D editors and configurators.

Does Three.js support coordinate conversion for interactive 3D applications?▼

Three.js supports coordinate conversion for interactive 3D applications by translating screen-space mouse and touch input coordinates into normalized device coordinates for accurate raycasting and object manipulation.

Why do my Three.js touch events feel unresponsive during object selection?▼

Touch events feel unresponsive when event management patterns lack optimization, requiring performant event handling and coordinate conversion techniques to keep raycasting and camera controls smooth during interactive selection.

Do I need a Raycaster to implement drag workflows in Three.js?▼

Yes, you need a Raycaster for drag workflows in Three.js to identify the target object under the pointer, combined with camera controls and selection helpers to maintain accurate object manipulation.
