* \brief Definition of the G4ChannelingFastSimCrystalData class
|
|
* The class inherits G4VChannelingFastSimCrystalData containing the data and properties
|
|
* related to the crystal lattice.
|
|
* The functions related to the crystal geometry (transformation of coordinates and angles
|
|
* from the reference system of the bounding box of the local volume to
|
|
* the crystal lattice co-rotating reference system and vice versa) and
|
|
* initialization function SetMaterialProperties are compiled in this class.
