SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill enables developers to implement interactive 3D experiences by handling user input (mouse/touch) and object selection via raycasting in Three.js.

Core Features & Use Cases

Raycasting-based object selection and click detection
Camera controls demos (OrbitControls, FlyControls, PointerLockControls, FirstPersonControls)
Mouse/touch input handling for interactive 3D scenes
Transform and Drag controls to manipulate objects in 3D space
Examples and patterns for building interactive web 3D experiences

Quick Start

Set up a basic Three.js scene, import OrbitControls, and implement a click-based raycasting interaction to select objects and control the camera.

FAQPage Schema

How do I implement raycasting for object selection in a Three.js scene?▼

Raycasting in Three.js tracks mouse and touch input to project a ray from the camera into the scene. This Skill provides the implementation patterns to detect object intersections for precise click-based selection and interactive workflows.

What's the best way to set up camera controls like OrbitControls in Three.js?▼

You can import control libraries like OrbitControls, PointerLockControls, and FirstPersonControls to manage the camera. This Skill provides examples for configuring these multiple control schemes within interactive web-based 3D applications.

Does Three.js raycasting work with both mouse and touch input?▼

Yes, Three.js raycasting supports cross-device input. This Skill handles both mouse and touch events to ensure interactive 3D object selection and manipulation functions consistently across different devices.

How do I use TransformControls to drag and manipulate 3D objects?▼

TransformControls and Drag controls allow users to directly move and manipulate objects in 3D space. This Skill includes implementation patterns to integrate these utilities alongside raycasting for complete interactive workflows.

Do I need to install additional libraries to use FlyControls and PointerLockControls?▼

You need the core Three.js library and its raycaster utilities. Optional control libraries like FlyControls and PointerLockControls are used to enable specific camera movement and first-person interactive workflows.
