Since Monday, my local paper has used a rather... interesting headline
for its year in review. I decided to POV it.
Happy 2021!

That's well done. I hope that when they write the review for 2021 next year they
can use a thumbs-up for the 1, and not a middle finger.
Let's all have a good POV-year.
Cheers
Ton

2021 HAS to be better than 2020!
Just during the last three weeks, my older brother and his wife came down with
Covid-19, plus two local friends of mine and one of their wives. They are all
recovering, which is good news of course. I'm still feeling fine, I'm happy to
say.
Here in the United States, there have been TWO equally devastating viruses that
we have had to deal with: One is called 'Covid-19', the other is 'President
Donald Trump.' :-P One infects the body, the other infects the mind. I can't
even imagine how the rest of the world views our current and crazy U.S.
situation.

Nice!
How did you get those blurred reflections? My few attempts over the years to use
micro-normals have always resulted in Moire patterns that I could not eliminate.

I rendered 10 frames, with each frame having the micronormal translated
and rotated randomly, then averaged the 10 frames.
In retrospect, the rotation was probably overkill. My initial trials
with translation only showed what looked like a blend of sharp
reflection and blurred reflection, and since I have noticed regular
patterns in the bumps normal, I figured rotating the normal would help
the blurriness. Rotating did not help, but reducing(!) bump_size did.
Evidently, there is some sort of phase transition, somewhere between 0.1
and 0.5, above which increasing bump_size led to poorer results. The
final scene uses bump_size 0.05.

The blurred reflection version is very nice, well done sir!

I agree 100% Kenneth, Trumpty Dumpty is obviously (and literally) insane. Stay
safe!

I tend to use some averaged micro-normals. Around 5 to 10 seems to work
well.
I prefer to use granite as my base pattern.
I also use rather large random translations after the scaling.
Also, when doing blurred reflection, I increase the AA recursion depth
to 5 or 6 and reduce the threshold to around 0.01 or even 0.001.
D. Trump is probably the worst leader to ever lead any country in Human
History. And, yes, he's bat shit crazy.

Granite-- I never thought of that. It is nicely 'random'. My own trials used
overlapped and rotated 'linear' patterns... like sine waves or scallop waves for
the normals, IIRC. Maybe that was the cause of my Moire patterns? I need to
experiment with your method.
