SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps developers implement input handling in Three.js projects, enabling raycasting-based selection, camera controls, and responsive user interactions in 3D scenes.

Core Features & Use Cases

Raycasting-based object selection and interaction with scene objects.
Integration of camera controls (OrbitControls, FlyControls, FirstPersonControls, etc.) for navigation and exploration.
Supports desktop and touch input to create interactive 3D experiences such as editors, demos, and product configurators.

Quick Start

Set up OrbitControls and a Raycaster to enable object selection via mouse clicks in a Three.js scene.

FAQPage Schema

How do I add mouse click object selection to a Three.js scene?▼

To enable object selection in Three.js, you combine a Raycaster with camera controls to cast rays from the pointer position, intersecting scene meshes to identify clicked objects. This Skill provides the integration pattern for raycasting, event handling, and object management across desktop and mobile devices.

Can I use OrbitControls and raycasting together in a 3D web app?▼

Yes, you can use OrbitControls and raycasting together in a 3D web app. This Skill combines camera controls for scene navigation with raycasting-based selection, allowing users to orbit, pan, and zoom while simultaneously supporting click-to-select interactions with 3D objects without input conflicts.

Does Three.js raycasting work with touch input on mobile devices?▼

Three.js raycasting works with touch input on mobile devices by mapping touch events to normalized device coordinates for the Raycaster. This Skill supports both desktop and mobile touch input, enabling interactive 3D experiences like product configurators and educational demos to function seamlessly across platforms.

What is the best way to set up interactive 3D product configurators in Three.js?▼

The best way to set up interactive 3D product configurators in Three.js is by integrating OrbitControls for scene navigation with raycasting for object selection. This Skill provides the necessary pattern for combining camera controls, event handling, and object management to create responsive configurators.

What Three.js dependencies do I need for interactive 3D scene controls?▼

To implement interactive 3D scene controls, you need the Three.js core library and OrbitControls for camera navigation. This Skill requires these components to establish a clear integration pattern for raycasting, mouse click event handling, and responsive object management within 3D web apps.

Why does my Three.js object selection not work with camera controls enabled?▼

Object selection may fail with camera controls enabled if raycasting and OrbitControls event handling are not properly integrated. This Skill addresses the issue by providing a clear integration pattern that synchronizes pointer events for object selection with camera navigation, ensuring both interactions function without conflict.
