Description:
A CmpMap is a compound
Mapping which
allows two component Mappings (of any class) to be connected together to form a more
complex Mapping. This connection may either be
"
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.
Constructor Function
Inheritance
The CmpMap class
inherits from the Mapping class.
Attributes
The CmpMap class does not define any
new attributes beyond those which are applicable to all Mappings.
Functions
The
CmpMap class does not define any new functions beyond those which are applicable to all
Mappings.
