The forward transformation of a UnitNormMap subtracts the specified centre and then transforms the resulting vector to a unit vector and the vector norm. The output contains one more coordinate than the input: the initial NIn outputs are in the same order as the input; the final output is the norm.
The inverse transformation of a UnitNormMap multiplies each component of the provided vector by the provided norm and adds the specified centre. The output contains one fewer coordinate than the input: the initial NIn inputs are in the same order as the output; the final input is the norm.
UnitNormMap enables radially symmetric transformations, as follows:
UnitNormMap has no attributes beyond those provided by Mapping and Object.

Construct a UnitNormMap
[in] | centre | An vector containing the values to be subtracted from the input coordinates before computing unit vector and norm. The length of this vector is the number of input axes of the mapping (and one less than the number of outputs). |
[in] | options | Comma-separated list of attribute assignments. |

Return a deep copy of this object. This is called by copy.
Each subclass must override this method. The standard implementation is:
for example Frame implements this as:
Reimplemented from ast::Mapping.
