[Proj] Geocentric Coordinates

[Eran Burstain]

Tnx, but how do i do it from code ?
I understand that I should initialize two projections with the
"+proj=geocent +ellps=XXXX" and "+proj=utm +zone=XX +ellps=XXXX" strings,
but then what ?
(Transformation should have 3 points for each input and 3 for each output
with height above ellipsoid, isn't it ?)
