The method also includes measuring coordinates of a second set of points on a second surface of a second portion of the 3D element and generating a second volume enclosed by the second set of points. The method continues by connecting the first and second volumes to form a combined volume, and generating coordinates of a third set of points on a third surface of the combined volume to form a 3D surface map of the element.5/7 ACQUIRE FIRST ACQUIRE SECOND SET OF POINTS OF SET OF POINTS OF ORGAN ORGAN 202 204 GENERATE FIRST GENERATE SECOND CLOSED SURFACE CLOSED SURFACE FROM FIRST SET FROM SECOND SET OF POINTS 2OF POINTS 206 208 FILL FIRST FILL SECOND CLOSED SURFACE CLOSED SURFACE TO FORM FIRST TO FORM SECOND VOLUME210 212 VOLUME COMBINE THE TWO VOLUMES AS A UNION, TO GENERATE COMPOSITE VOLUME 214 GENERATE SURFACE OF ORGAN BY COVERING COMPOSITE VOLUME 216 GEND FAD
