WebAug 7, 2012 · So for example, if you have one point which should lie on the ellipse, then you could compute the distance to the two foci, add those lengths, and know that sum to be equal to 2a, where a is the length of the semimajor axis. Then you get the length of the semiminor axis as b = sqrt(a 2 - f 2), where 2f is the distance between your foci.
