Detailed Description

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 two-dimensional 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.

◆ map()

RealPoint2D map ( [in] RealPoint2D  aPoint)

Forward 2D mapping function.

◆ mapInverse()

RealPoint2D mapInverse ( [in] RealPoint2D  aPoint)

Inverse 2D mapping function.

The following invariant must hold: map(mapInverse(p))=p. This effectively rules out non-bijective mappings.
