  About thirty high-field magnetoresistance Stereographic Maps have been
measured for metals between Fifties and Seventies but no way was known till now
to compare these complex experimental data with first-principles computations.
We present here the method we developed to generate Stereographic Maps directly
from a metal's Fermi Surface, based on the Lifshitz model and the recent
advances by S.P. Novikov and his pupils. As an application, we test the method
with an interesting toy model and then with Au and Ag.
