There are other options (like the gawdawful DoD standard that comes
with
WMM2010); it just takes quite a lot more time.
Yes the DoD standard takes a lot more time but ......
The magnetic field doesn't change that rapidly so there is no need to
recompute it if you haven't traveled very far, except at the dipoles and
that is another story where perhaps one wants that gawdaful code :-)
The DoD code is well separated into distinct steps so one could spread
the
calculation out over *many* frames ameliorating the 'hit' on the rest of
the program
just idle thoughts .......
