TEveMagField Class Reference
Graphics » 3D Graphics » Event Display

Abstract base-class for interfacing to magnetic field needed by the TEveTrackPropagator.

To implement your own version, redefine the following virtual functions: virtual Double_t GetMaxFieldMagD() const; virtual TEveVectorD GetFieldD(Double_t x, Double_t y, Double_t z) const;

See sub-classes TEveMagFieldConst and TEveMagFieldDuo for two simple implementations.

NOTE: For backward compatibility float versions are the primary sources of field information in this base-class. The float versions are not used in TEve and can be ignored in sub-classes.

NOTE: Magnetic field direction convention is inverted.
