The root Object3D of the hierarchy to calculate the world space radius for.
The radius of the world space bounding sphere.
// Assuming 'rootObject' is the root of your Object3D hierarchy with mesh components
const worldRadius = radiusHierarchy(rootObject);
console.log(`World space radius: ${worldRadius}`);
Calculates the world space radius of an Object3D hierarchy.
The function returns the radius of a bounding sphere that encloses all mesh components in the hierarchy of the provided Object3D. This can be useful for visibility testing, collision detection, or spatial queries within a 3D environment.
