Original s‐rep of a hippocampus and its improved s‐rep. Left: lateral and superior view of a hippocampus and its initial s‐rep (magenta, up spokes; cyan, down spokes; black, skeletal locus; yellow, implied surface). Right: improving the initial s‐rep by: (1) adjusting the spoke lengths to precisely meet the boundary surface of the hippocampus (grey) and (2) pointing the tip crest spoke (red) to the right position.
