"
in series"
(where the first Mapping is
used to transform the coordinates of each point and the second mapping is then applied
to the result), or "
in parallel"
(where one Mapping transforms the earlier
coordinates for each point and the second Mapping simultaneously transforms the later
coordinates).
Since a CmpMap is itself a Mapping, it can be used as a component in forming further CmpMaps. Mappings of arbitrary complexity may be built from simple individual Mappings in this way.
