/**
 * A bounding box component that provides both axis-aligned and oriented bounding boxes
 * along with bounding spheres for 3D objects.
 *
 * The BoundingBox class extends DIVENode and creates visual representations of the
 * bounding volumes of 3D objects. It supports two modes:
 * - **Axis-aligned bounding box (AABB)**: Aligned with the world coordinate system
 * - **Oriented bounding box (OBB)**: Aligned with the object's local coordinate system
 *
 * The class also automatically computes a bounding sphere that encompasses the entire object.
 * Both the bounding box and sphere can be visualized as wireframe helpers.
 *
 * @example
 * ```typescript
 * // Create a bounding box for a 3D object
 * const mesh = new Mesh(geometry, material);
 * const boundingBox = new BoundingBox(mesh, false, 0x00ff00);
 *
 * // Show the bounding box wireframe
 * boundingBox.setBoxHelperVisible(true);
 *
 * // Access bounding box properties
 * console.log('Center:', boundingBox.center);
 * console.log('Size:', boundingBox.size);
 * console.log('Radius:', boundingBox.radius);
 * ```
 *
 * @example
 * ```typescript
 * // Create an axis-aligned bounding box
 * const aabb = new BoundingBox(mesh, true, 0xff0000);
 *
 * // Show the bounding sphere wireframe
 * aabb.setSphereHelperVisible(true);
 * ```
