This option structure contains the optional controls for
PK_DEBUG_BODY_compare


Description of fields:



max_diffs         If max_diffs = 0, only global comparison tests will
                    be performed on the bodies, for instance, comparison of
                    the number of vertices/edges or faces in the body.
                    If max_diffs > 0, then more expensive tests will
                    first attempt to match face pairs, each pair consisting
                    of one face selected from each body on the basis of
                    broad similarities. Analysis will then be performed to
                    detect any differences between each face of a matched pair.
                    Analysis of remaining matched pairs will continue until
                    max_diffs matched face pairs have been found which are
                    considered non-identical by those comparison tests which
                    have been specified.
                    The faces which remain unmatched represent a significant
                    difference between the bodies, therefore the option to
                    return non-matched faces is recommended. The default
                    value of the field is zero.


all_tests         Perform all local comparison tests. If max_diffs = 0,
                    this argument will be ignored.


num_tests         Perform max_diffs numerical comparison tests.


acc_dev_tests     Perform max_diffs accurate deviation comparison tests.


tol_dev_tests     Perform max_diffs deviation comparison tests to within
                    session precision.


tol_tests         Perform max_diffs tolerance comparison tests.


class_tests       Perform max_diffs class comparison tests.


sense_tests       Perform max_diffs sense comparison tests.


missing_tests     Perform max_diffs missing entity comparison tests.


non_match_tests   Perform max_diffs non-matched entity pairs comparison
                    tests.
