        RaycastHit hit;
        if (Physics.Raycast(ray, out hit))
        {
            Handles.color = Color.green;
            Handles.zTest = UnityEngine.Rendering.CompareFunction.LessEqual;
            Handles.DrawLine(transform.position, hit.point);
            Handles.DrawWireDisc(hit.point, hit.normal, 0.5f);

            Handles.color = Color.red;
            Handles.zTest = UnityEngine.Rendering.CompareFunction.Greater;
            Handles.DrawLine(transform.position, hit.point);
            Handles.DrawWireDisc(hit.point, hit.normal, 0.5f);
        }
