You input the lengths of three lines and their starting coordinates, and the
engine calculates where they intersect ( in three dimensions).
I solved the problem when I was in the mental hospital in 1988. It was all
I could do to keep my sanity. This is ~some~ of the math used to determine
GPS coordinates. It also calculates the two points as the result of the
intersection of three spheres.
