Interface defining an arbitrary bijective mapping from R^2 to R^2.
This interface provides methods to define an arbitrary bijective mapping from R^2 to R^2, i.e. from the twodimensional space of real numbers onto itself, as is representable by the double floating point type. The mapping must be bijective, i.e. map a pair of real numbers to exactly one other pair of real numbers and vice versa, to facilitate a working inverse. Bijectiveness also implies completeness, i.e. for every pair of real numbers there must be another pair that is mapped upon them.
RealPoint2D map  (  [in] RealPoint2D  aPoint  ) 
Forward 2D mapping function.
RealPoint2D mapInverse  (  [in] RealPoint2D  aPoint  ) 
Inverse 2D mapping function.
The following invariant must hold: map(mapInverse(p))=p
. This effectively rules out nonbijective mappings.
