>How the heck did "" get in there?
Something like
(E(t)-P).(E(t)-P)
where E is the ellipse and P is the point.
>Is there a reason not to use the cubic formula in this situation?
Numerical stability in edge cases, which will occur for code exercised as extensively as Parasolid's.
I guess you could a Bernstein version of the cubic formula, though I've not seen one derived in the wild. It would be nice to have as well as Bernstein quartic formula. The Bernstein quadratic is easy.
