  I think an infinite object does not have a bounding box at all.

  I don't understand how you came to this conclusion.
  An infinite number of intersection points to calculate what? For one
pixel we need one intersection point (unless using antialiasing, which
means we may need something like 9 intersection points). What do you need
to calculate an infinite amount of intersection points for?
