ConstReadonlyMAX_ELBOW_FLEXION: 2.53Maximum safe elbow flexion: 145° (2.53 radians)
Full elbow flexion is approximately 145-150°, allowing natural bending and manipulation in joint lock techniques.
ReadonlyMAX_SHOULDER_ROTATION: 1.57Maximum safe shoulder rotation: ±90° (±1.57 radians)
Safe shoulder rotation range for circular Hapkido movements without risking impingement or structural damage.
ReadonlyMAX_WRIST_HYPEREXTENSION: 1.22Maximum safe wrist hyperextension: 70° (1.22 radians)
Typical wrist extension limit is 70-90°. We use 70° as a safe threshold for realistic joint locks without causing injury.
Anatomical safety constants for Tae (Lake) joint lock animations
These limits document safe physiological ranges for joint manipulation techniques. The constants serve as reference documentation validated by Korean martial arts experts and inform the design of all joint lock animations to ensure realistic Hapkido mechanics without exceeding anatomical safety thresholds.
Note: These are documentation constants. The actual animation rotations are designed to stay within these limits naturally through authentic joint lock biomechanics.
