size gives us our spheroid coefficients (A, B, C). Then, we want to find out for each vert its (a, b, c) triple (proportional to (A, B, C) one).
Ellipsoid basic equation: (x^2/a^2) + (y^2/b^2) + (z^2/c^2) = 1. Since we want to find (a, b, c) matching this equation and proportional to (A, B, C), we can do:
m = B / A
n = C / A
hence:
(x^2/a^2) + (y^2/b^2) + (z^2/c^2) = 1
-> b^2*c^2*x^2 + a^2*c^2*y^2 + a^2*b^2*z^2 = a^2*b^2*c^2
b = ma
c = na
-> m^2*a^2*n^2*a^2*x^2 + a^2*n^2*a^2*y^2 + a^2*m^2*a^2*z^2 = a^2*m^2*a^2*n^2*a^2
-> m^2*n^2*a^4*x^2 + n^2*a^4*y^2 + m^2*a^4*z^2 = m^2*n^2*a^6
-> a^2 = (m^2*n^2*x^2 + n^2y^2 + m^2z^2) / (m^2*n^2) = x^2 + (y^2 / m^2) + (z^2 / n^2)
-> b^2 = (m^2*n^2*x^2 + n^2y^2 + m^2z^2) / (n^2) = (m^2 * x^2) + y^2 + (m^2 * z^2 / n^2)
-> c^2 = (m^2*n^2*x^2 + n^2y^2 + m^2z^2) / (m^2) = (n^2 * x^2) + (n^2 * y^2 / m^2) + z^2
All we have to do now is compute normal of the spheroid at that point:
n = (x / a^2, y / b^2, z / c^2)
And we are done!
