  I don't think there's an analytical solution for the intersection of a cone
and any given mathematical surface.
  You have probably heard about raytracers which use cones instead of rays,
but those raytracers most probably support just triangles (the intersection
of a cone and a triangle is possible and rather easy to calculate).
