Well, I was kind of thinking that an infinite plane would require an
infinite number of rays to trace since there would be an infinite number of
places that a ray could intersect (and that would be potentially in view).

However, on reflection, it occurs to me that:
a) the number of rays is limited by the resolution
and
b) that would just be silly.

Toodleoo.
