Detailed Description

Geometrical description of a sensor.

Class resembling GeometricDet class. Slight changes were made to suit needs of the TOTEM RP description. Each instance is a tree node, with geometrical information from DDD (shift, rotation, material, ...), ID and list of children nodes.

The translation and rotation parameters are defined by local-to-global coordinate transform. That is, if r_l is a point in local coordinate system and x_g in global, then the transform reads:

   x_g = rotation * x_l + translation

July 2020: Migrated to DD4hep To avoid any regression with values from XMLs / Geant4, all lengths are converted from cm (DD4hep) to mm.
