"
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.
