NAME

cxPyrConCompare - compare two set of vertices based on the equivalence type

C SPECIFICATION

#include <cx/Pyramid.h>

long cxPyrConCompare( long n0, long *x0, long n1, long *x1,
   cxPyrEquivType type )

FORTRAN SPECIFICATION

integer function cxPyrConCompare( n0, x0, n1, x1, type )
integer n0, x0(n0), n1, x1(n1), type

PARAMETERS

n0: The number of vertices in x0.
x0: First vertex list.
n1: The number of vertices in x1.
x1: Second vertex list.
type: Equivalence type to govern comparison of vertex lists.

FUNCTION RETURN VALUE

Returns 1 if the two vertex lists are equivalent, or 0 otherwise.

DESCRIPTION

cxPyrConCompare compares the two vertex lists x0 and x1 governed by the equivalence type type. The equivalence types and their ordering restrictions are:

CX_PYRAMID_EQUIV_IDENTICAL sequences must be exactly identical.

CX_PYRAMID_EQUIV_IDENTICALR sequences must be exactly identical or be identical when one is reversed (same as CX_PYRAMID_EQUIV_IDENTICAL with reversal allowed).

CX_PYRAMID_EQUIV_CYCLIC sequences must be identical under some cyclical shift (or rotation) of one sequence.

CX_PYRAMID_EQUIV_CYCLICR sequences must be identical under a cyclical shift of one sequence or of its reversal (same as CX_PYRAMID_EQUIV_CYCLIC with reversal allowed).
