Locating atoms from angles-Help!

I wonder if someone can help me with a problem.
I'm writing a protein folding program that uses
a simplified representation storing only the amino
acid sequence, C-alpha coordinates and the Phi and
Psi dihedral angles.
At the end of the program, I need to reconstruct
a detailed atomic model of the molecule. With the
dihedral angles, I know the relative orientation
of the backbone C, N and O atoms between one residue
and its neighbour. But how do I get the starting
coordinates of the FIRST N atom? Once I get that,
I can work out the rest of the atoms.
Any ideas will be greatly appreciated.
Thanks in advance.
