You can add clickable object selection to a Three.js scene by using raycasting to detect mouse clicks and touches on 3D objects, enabling click-to-select and hover effects without building custom input handling logic from scratch.

The best way to implement camera navigation in Three.js is using pre-built Orbit, Fly, FirstPerson, PointerLock, and Trackball controls, which provide intuitive scene navigation out of the box for interactive 3D viewers.

Yes, you can detect mouse hover events on 3D objects in a Three.js web application by utilizing raycasting utilities to track pointer movement over meshes, enabling interactive hover effects for product viewers and virtual showrooms.

Raycasting in Three.js works by projecting a 2D screen coordinate into a 3D ray to intersect with scene objects, while coordinate conversion utilities translate mouse and touch inputs into 3D world space for accurate drag interactions.

Yes, this Three.js interaction approach supports touch events for mobile 3D viewers by providing pre-built input handling that detects touches on 3D objects, enabling click-to-select and drag interactions across both mouse and touch interfaces.
