Detailed Description

Class for interfacing to the geometry; it also builds and manages the look-up tables for fast access to geometry and alignment information for sensitive alignable volumes: 1) the look-up table mapping unique volume ids to TGeoPNEntries. This allows to access directly by means of the unique index the associated symbolic name and original global matrix in addition to the functionality of the physical node associated to a given alignable volume 2) the look-up table of the alignment objects associated to the indexed alignable volumes

◆ applyMisalignent()

void GeometryManager::applyMisalignent ( bool  applyMisalignment = true)
