Dear Fellows,

Here's a little Radiance teaser to exercise the noggin(*).

Explain the absence of level 2 ambient sampling (blue) markers
directly under the box in Figure 2 of the Third Radiance Tech Note.
Level 2 markers are scattered across the rest of the plane, why not
under the box?

The Prize? Something money can't buy: the respect of your peers!

The Judge? As I'm not too sure of the reason myself, I nominate
whasisname.... Greg. Post answers to this thread.

-John

(*) noggin
n : informal terms for a human head [syn: attic, bean, noodle]

Actually, my entry *was* serious...

I just chose to make it a little cryptic, so that others would
have a chance to find their own solution, or to translate mine
into plain english.

Of course. As the official judge, I should have spotted the truth in your jest. As you also gave your response right away, you deserve the first prize. Anyone want to try for second place by explaining what Schorsch meant in his response (attached)?

The blue dots are coming late for the seats in
that part of the auditorium...

The explanation is not particularly technical. Pretty much
everybody on this list could figure it out by considering the
sequence of ambient ray propagation, and a minimal amount of
spatial imagination. A look at the diagram on page 552 of the
book might make it even more obvious.
