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 routines beyond those which are applicable to all Mappings.
