Detailed Description

template<typename G>
struct Acts::InterpolatedBFieldMapper< G >

struct for mapping global 3D positions to field values

Template Parameters

DIM_POS	Dimensionality of position in magnetic field map
DIM_BFIELD	Dimensionality of BField in magnetic field map

Global 3D positions are transformed into a DIM_POS Dimensional vector which is used to look up the magnetic field value in the underlying field map.
