Holder for +- extents in 3 dimensions.
Definition: BDSExtent.hh:39
BDSExtent Translate(const G4ThreeVector &offset) const
Provide a new copy of this extent with an offset applied.
Definition: BDSExtent.hh:125
Class to provide scaling and a base class pointer for interpolator fields.
BDSExtent ExtentNoOffset() const
Extent of field without any offset (ie in its own coordinate frame).
BDSExtent Extent() const
For now, we will ignore any rotation of the transform. TODO.
BDSExtent extentNoOffset
Extent without offset.
G4double eScaling
E field scaling value.
Interface for BDSIM electric fields that may or may not be local.
Definition: BDSFieldE.hh:37
G4Transform3D transform
Transform to apply for the field relative to the local coordinates of the geometry.
Definition: BDSFieldE.hh:77
Interface for all interpolators containing basic extent of validity.
