Medical Sphere Estimation - Realistic Hip Center Analysis

Clinical Context: This simulation represents femoral head center estimation from limited surface points, as typically acquired during hip surgery. The default parameters (10cm radius, 6mm measurement error) are based on typical adult femoral head dimensions and surgical measurement accuracy.
