Hello,

  Does any of you know how I could calculate the *exact* coordinates
of the tetrahedron points' coordinates? I mean, yes of course I looked
at include/shapes2.inc, but they seem to be approximations at 0.1 %, and I
need a greater precision (for a scientific job). So I'm looking for
the formulae that could give me these coordinates, or the equations from
which I could draw them.

  Any hint would be appreciated, even if it is just a geometry hint.

  E-mail answers will be summarized and posted here, news article answers
are welcome. Thanks in advance,

Roland.
