Greetings:

I have a question that possibly _anyone_ could answer:

I am searching for a simpler equation to determine the 3D coords.  of
a point defined by the vertex of a tetrahedron.

If you have the lengths of the edges of the tet., and you have the
base cordinates, is there a simple algorithm for determining the
coords. of the vertex?

Thanks all,

Mike Nielsen

P.S. - In case my terminolgy is wrong:  tetrahedron - three sided pyramid.

Thanks again
