You can make 3D objects clickable by implementing raycasting to detect mouse clicks and touch events. This enables object picking and selection within your Three.js scene, allowing users to interact directly with specific meshes.

You can use various camera controls including Orbit, Fly, FirstPerson, and PointerLock modules. These schemes allow users to navigate and manipulate the camera view dynamically within Three.js applications.

You can add transform gizmos to translate, rotate, and scale 3D objects by integrating specialized control modules. These gizmos enable direct manipulation of selected objects within your Three.js scene.

Yes, you can detect user input by attaching event listeners for mouse clicks, touch events, and keyboard inputs. This functionality integrates with existing Three.js scenes to provide dynamic user experiences.

Building a 3D product configurator involves combining raycasting for object selection with camera controls like OrbitControls. This lets users click parts to change color or texture and view the product from all angles.

Raycasting is needed for object selection because it calculates intersections between a projected line from the camera and 3D meshes. This mechanism accurately identifies which object a user clicked in the Three.js scene.
