#!F-adobe-helvetica-medium-r-normal--18* #!N #!N #!Rtall215 Neighbors Component #!N #!N #!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 Topic #!EF #!N #!N #!Ltall217,dxall217 h Box Component #!EL #!N #!F-adobe-times-medium-i-normal--18* #!N
