#!N #!N Functional Details #!N #!N Reduces the resolution of regularly
connected grids. Box filtering is applied to minimize aliasing effects in
the components that are associated with the grid. It filters and
reduces the number of items in the "data" component of the
input field and also in any components that are position or
connection dependent. #!N #!I0 #!N #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* input
#!EF #!EF #!I50 #!N is the field to be reduced. It
must have regular connections. #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* factor #!EF
#!EF #!I50 #!N specifies the reduction factor(s) to be used in
reducing the resolution of the field. #!I0 #!N #!N If this
parameter specifies: #!N #!I0 #!N #!F-adobe-times-medium-r-normal--18* #!N #!N #!I30 #!N o
#!F-adobe-times-medium-i-normal--18* a single scalar value: #!EF the output is reduced by
that factor in all dimensions. #!N #!I30 #!N o #!F-adobe-times-medium-i-normal--18* a
vector: #!EF each vector element is applied to the corresponding dimension.
#!N #!I30 #!N o #!F-adobe-times-medium-i-normal--18* a list of scalars or vectors:
#!EF the output is a group of fields, each with the
corresponding factor applied. #!N #!I0 #!N #!EF #!N #!N #!N Components
#!N #!N All components in the input are propagated to the
output. Components dependent on "positions" or "connections" are filtered. #!N #!N
