Examples of Biorthogonal Analysis
One of Thompson s original examples is famous beyond all others: the comparison of Diodon with Orthagoriscus (= Mola) in Fig. V-2. Thompson’s description of his grid pair has already been excerpted on page 70. For reanalysis, I have represented the two outlines by seven point pairs and circular arcs connecting them. The points include the mouths and the axial ends of cranial and caudal margins of the dorsal and anal fins, together with points which correspond, according to Thompson’s drawings, on each of the arcs from mouth to fins. The circular arcs pass through ordinary points approximately midway between consecutive landmark pairs in Thompson’s figure. Of course, the fins, being outside the resulting boundaries, are omitted from the computed representation.
