I followed the advice of subdividing the mesh in small triangles and 
launched this test in high quality to show how it is. Hope you like. I 
will show images at the rate of one every 7-10 days in this same thread

Yes, I will share the documented source with examples as soon as it is

Yes, this is excellent   :)
I like the way the plane turned out, and the focal blur is a good choice.

TBTFH is nicely sculpted - though perhaps the white on white with a white "sky"
and whitish plane with white reflections is a bit washed out.
Sprinkle some Irish freckles in there.  :D

Thanks!   It's always nice to have a few new things to look forward to.

I wholly understand.   I have large swaths of code that are Jackson Pollack in
nature, and others where I look open the file, look at the code, wonder what it
all is, and what it's for, ... and then realize that I'm the one who wrote it.

:D

Love the thought. :)

I am looking at an animation I made 10 years ago, wondering what I was 
thinking of with the mechanics.

This looks good - but I'm confused.
I haven't had a chance to look through your code and see what you're doing.

Is that "stripe" supposed to be missing?
(I like the effect anyway  :) )
This took about 13 min to parse on my tower at work, and not very long to render
for me - what are those huge times you're posting?

The torus that I'm working on doesn't take nearly that much time to parse on my
laptop.

I'll send you an email and maybe we can compare notes.

your reply to BGimeno encouraged me to try on my machine (lowly I3), and now I'm
confused.  run with:

  $ povray +w1024 +h768 +a0.05 +am2 +ag1 -j +q11 +itorus-test6.pov

parsing is well under a minute, and (4 threads) radiosity + trace total up to
under 20 minutes.

BGimeno: looks like your system would benefit from some tlc + admin.  ;-)

just over 20 mins.  </sighs>

parse: 52.5 s.
bounding: .05 s.
radiosity: 130.6 s.
trace: 1157.2 s.

So, I'm triply confused.
a)  There's a quality 11?    (Throws horns, bangs head)

b) I don't see a radiosity block in this scene...

c) I copied your settings and pasted it into QTPOV-Ray like so:

+w1024 +h768 +a0.05 +am2 +ag1 -j +q11 +ITBTFH_2018-09-07.pov

Parser Time
  Parse Time:       0 hours  0 minutes 49 seconds (49.470 seconds)
              using 1 thread(s) with 0.-01 CPU-seconds total
  Bounding Time:    0 hours  0 minutes  0 seconds (0.063 seconds)
              using 1 thread(s) with 0.-01 CPU-seconds total
Render Time:
  Photon Time:      No photons
  Radiosity Time:   No radiosity
  Trace Time:       0 hours  0 minutes 33 seconds (33.499 seconds)
              using 4 thread(s) with 0.-04 CPU-seconds total

 It took 1:24.

so, actually, quadruply confused - since it took over 13 min to do at work on
what I believe is an i5.

:-)  section (docs v3.8, section 3.2.8.3)

immediately below the '#include' lines, the (second) global_settings block.

that's roughly en par.

and that is *fast*.

the work machine a Linux box too?

mine says 'Intel(R) Core(TM) i3-2100 CPU @ 3.10GHz.  os is Slackware 14.1.

did you compile POV-Ray or installed a pre-built binary?  fwiw, I compile + add
"-march=native -mtune=native" to the compiler flags.

I see.
For some reason the page I went to specified that section as I/O no
restrictions, but I found quality 9, 10, 11.
My message pane window displays the lower redundant value of 9.

Oh THAT radiosity "block".
First of all, that's a radiosity LINE, son.
And second of all, these damned dried frog pills that I imported from Scotland
send up a cloud of dust every time I bite into them, so I missed that sections
when I was scrolling down...

Well YEAH - WITHOUT radiosity.
I enable that commented line, and it took 27:40.   I thought I was doing ok when
it was at 3:30 and started actually rendering a visible scene, but then it hit
that BTFH....  :|


> the work machine a Linux box too?

Nope.
And now that you mention it, it's a 32-bit Win 7 box that has some
network-linked account......   I wonder what else that's slowing down....
That would explain a LOT about some of my spreadsheet woes.

I installed it as per Dick Balaska's instructions, so I'm just hoping he knows
what he's doing   :D

So it seems that your i3 is doing just fine   :)
