Objects #!N #!EC #!N #!N A Product Array is a compact 
encoding of a generalized notion of a regular grid. It is 
frequently used to describe a rectilinear grid as a product of 
Regular Arrays; in such a case, it is generally more convenient 
to use the  #!F-adobe-times-bold-r-normal--18*   gridpositions #!EF keyword described earlier. #!N #!N 
A Product Array is the set of all possible sums of 
the points of the terms forming the product. For example, the 
product of a set of Arrays, each of which is a 
Regular Array as described above, is a lattice of points with 
basis vectors equal to the deltas of the Regular Arrays and 
origin equal to the sum of the origins of the terms. 
A product of a Regular Array with an irregular Array is 
a "semi-regular" grid whose unit cells are prisms. A Product Array 
is specified by a list of  #!F-adobe-times-bold-r-normal--18*   term #!EF clauses naming 
the Arrays that form the product. The last term varies fastest 
in the resulting list of positions. #!CForestGreen #!N #!N  #!F-adobe-courier-bold-r-normal--18*   #!N
