SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Three.js interaction enables developers to handle user input, detect object selection, and control the camera for immersive 3D experiences.

Core Features & Use Cases

Raycasting for click detection and object selection
OrbitControls and other camera controls for navigation
Pointer and touch input handling with responsive interactions
Hover feedback and selection patterns for interactive scenes
Use Case: build product explorers, simulations, or games with interactive objects

Quick Start

Create a basic Three.js scene, enable OrbitControls and a Raycaster, then try clicking objects to observe selection.

FAQPage Schema

How do I detect clicked objects in a Three.js scene?▼

Object selection in Three.js is handled through raycasting, which tracks pointer input coordinates and intersects them with 3D meshes. This enables robust click and tap detection across interactive scene objects.

Can I use OrbitControls and raycasting together for interactive 3D navigation?▼

Yes, OrbitControls and raycasting work together to provide smooth camera navigation alongside click selection. You can enable both to handle pointer input for orbiting while detecting object interactions.

What is the best way to add hover feedback to Three.js objects?▼

Hover feedback in Three.js is implemented by combining raycasting with pointer move event handling. As the raycaster intersects objects during pointer movement, you can apply visual feedback patterns to highlight targeted meshes.

How do I handle touch input for selecting 3D objects in Three.js?▼

Touch input handling for Three.js object selection uses raycasting to map touch coordinates to 3D scene space. This enables responsive tap interactions and object selection on mobile devices.

Does this Three.js interaction approach work for building product explorers and simulations?▼

Yes, Three.js interaction is designed for building product explorers, simulations, and games. It provides the raycasting, camera controls, and input handling needed for interactive 3D object experiences.
