You have to move the viewer to the origin and translate the terrain
the same amount. Al calculations should be done in double and the
results put in the performer structures (float). There is a mail in the
archives describing this principle. I think it was Rob Jenkins who
wrote it. It should be in the 1996/1997 archives.
