Thanx guys. Found Some stuff to calculate the norms. One question. the new point nx ny nz calculated after the cross product. Does glNormal3f() see that as a vector starting at (0,0,0) going thru (nx,ny,nz)?

It is just a direction. It doesn't start anywhere.

Yes you could look at it that way. Remember that only the direction and length of that vector matter however (and the length should be 1.0 if you want correct lighting).
