9. Subdivision vs QMC
At first sight, you might think the
adaptive subdivision image is bet-
ter (less noisy). But if you look
closely, the noise is just different,
not ‘better’. In the shadow area
you get a ‘blotchy’ kind of noise,
compared to the QMC example
which is sharp constant noise.
The top image is the adaptive
subdivision AA, the bottom one is
the adaptive QMC AA.
