**B. Physics Simulation Capabilities

# Python API for VR physics (PyBullet)
def simulate_interaction(vr_hand, prototype):
    # Real-time physics in VR
    p.connect(p.VR)
    p.setGravity(0,0,-9.8)
    obj_id = p.loadURDF(prototype.path)

    while vr_session_active:
        hand_pos = get_controller_position()
        p.applyExternalForce(
            obj_id, -1, 
            force=[hand_pos.x*10, hand_pos.y*10, 0],
            pos=[0,0,0],
            flags=p.WORLD_FRAME
        )
        p.stepSimulation()

3. Multi-User Collaboration Features

**A. Real-Time Design Markup

// Unity-based annotation system
public class VRDesignComment : MonoBehaviour
{
    public void RecordAnnotation()
    {
        var annotation = new DesignNote(
            transform.position,
            voiceRecording.clip,
            DateTime.Now,
            currentUser.ID
        );

        CloudSync.UploadAnnotation(prototypeID, annotation);
    }
}

**B. Version Comparison Tools
