Detailed Description

Class for getting the jacobian d_mother/d_component for various kinds of alignment parametrisations, i.e. the derivatives expressing the influence of the parameters of the 'component' on the parameters of its 'mother'. This is needed e.g. to formulate constraints to remove the additional degrees of freedom introduced if larger structures and their components are aligned simultaneously. The jacobian matrix is

/ dp1_l/dp1_i dp1_l/dp2_i ... dp1_l/dpn_i | | dp2_l/dp1_i dp2_l/dp2_i ... dp2_l/dpn_i | | . . . | | . . . | | . . . | \ dpm_l/dpm_i dpm_l/dpm_i ... dpm_l/dpn_i /

where p1_l, p2_l, ..., pn_l are the n parameters of the composite 'mother' object and p1_i, p2_i, ..., pm_i are the m parameters of its component.

Note that not all combinations of parameters are supported: Please check method isOK() before accessing the derivatives via operator(unsigned int indParMother, unsigned int indParComp).

Currently these parameters are supported:

mother: rigid body parameters,
component: rigid body, bowed surface or two bowed surfaces parameters.
