Raycasting and object selection in a Three.js scene are implemented by detecting pointer hits against meshes, enabling click selection, hover feedback, and interactive state changes. This handles input event normalization and hit detection automatically.

Configuring OrbitControls for Three.js involves attaching the control module to the camera and DOM element to manage rotation, zoom, and pan interactions. This Skill configures OrbitControls and normalizes pointer and touch events for responsive camera movement.

Three.js supports touch input for 3D object interaction through normalized pointer events that map touch coordinates to 3D raycasts. This Skill provides touch event normalization, enabling reliable tap selection and drag workflows on mobile devices.

Drag and transform workflows for selected meshes in Three.js require managing selection state and attaching gizmos to targeted objects. This Skill manages selection state and provides coordinate conversion utilities for transforming objects in editors and visualizations.

Three.js raycasting works simultaneously with keyboard movement controls by separating pointer hit detection from camera navigation logic. This Skill supports click selection, hover feedback, and keyboard movement patterns within the same interactive scene.
