A wrapper class for BDSFieldMag that rotates it.
G4RotationMatrix * rotation
The rotation matrix used to rotate the coordinates.
G4RotationMatrix * antiRotation
The opposite rotation matrix used to transform the resultant field vector.
BDSFieldMagSkew()=delete
Private default constructor to force use of supplied ones.
BDSFieldMag *const field
virtual G4ThreeVector GetField(const G4ThreeVector &position, const G4double t=0) const
Get the field - local coordinates, and rotated.
Interface for static magnetic fields that may or may not be local.
