#!N The "neighbors" component represents information about the neighbors of each
connection element. The number of items in this component must match
the number of items in the "connections" component. The number of
entries in each item must match the number of faces (for
3-D) or edges (for 2-D) in the connection element. For example,
each item in the "neighbors" component for triangle connections has three
entries, while each item in the "neighbors" component for tetrahedral connections
has four entries. #!N #!N For simplexes in #!F-adobe-times-medium-i-normal--18* n #!EF
dimensions (for example, triangles and tetrahedra), each item of the neighbors
Array consists of #!F-adobe-times-medium-i-normal--18* n+1 #!EF integer indices into the connections
Array identifying the #!F-adobe-times-medium-i-normal--18* n+1 #!EF neighbors of the simplex; the
#!F-adobe-times-medium-i-normal--18* i #!EF th of the #!F-adobe-times-medium-i-normal--18* n+1 #!EF indices corresponds
to the face opposite the #!F-adobe-times-medium-i-normal--18* i #!EF th vertex of
the simplex. For quads, cubes, and so on, each item of
the neighbors Array contains 2 #!F-adobe-times-medium-i-normal--18* n #!EF integer indices into
the connections Array identifying the 2 #!F-adobe-times-medium-i-normal--18* n #!EF neighbors of
the polyhedron. The pointers are in the order #!F-adobe-times-medium-i-normal--18* -x[1]+x[1]-x[2]+x[2] ...
-x[n]+x[n] #!EF , meaning that the first index points to the
neighbor in the #!F-adobe-times-medium-i-normal--18* -x[1] #!EF direction, the second to the
neighbor in the #!F-adobe-times-medium-i-normal--18* +x[1] #!EF direction, and so on, where
the #!F-adobe-times-medium-i-normal--18* x[n] #!EF dimension varies fastest in the representation of
the point indices in the interpolation element. Faces without neighbors are
indicated by an index of -1. #!N #!N #!N #!F-adobe-times-medium-i-normal--18* Next
