  I have done so and would not undertake the task again unless the need were
very, very, great. Even though I have done so my largest hand coded mesh
object was minuscule in comparison to what most computer generated mesh
utilities output in quantity.

I added Ron's suggestions. Thanks Ron.
  I also corrected the allegation 20. You got a point.
  I still think that the allegations should score 1 to 3 points. I think
it's much more notorious to be able to code all the Colefax's includes than
just know the format of a df3 file.
  The scores are my personal estimations. If you disagree on some of them
(too low or too high), I'll be glad to listen.
  With this new test my personal score is now 25. (The new questions start

  Hi, Gail, Ken, and Marc. Where do the v3.0 docs do better compared with
the v3.1 docs? Is this the docs in general or a specific format (.html,
.pdf, Word, etc.)?

 The content appears to be the same only the format has changed. I believe
we discussed this in .general a while back didn't we ?

Well, since I do have a mesh modeller, I can't really bring myself to
messing with vertex coords. Besides, a truly hardcore POVer would hardly
ever need triangle meshes. CSG, people! :)

I blatantly ignore all "non-hollow object", "scaled by 0" etc warnings,
because I know when they don't affect me. 'hollow' is such a long word to
type :)

  I'll post an image in the images group that I would like to hear how you
would csg a similar shape or I would like to hear your concession that
modelling it with triangles was the logical choice. Bear in mind when
you view the image the object pictured was constructed for Pov v2.2 quite
some time ago and was never really meant for public display.

I will post it under the thread title of "Triangles for Estonia" :-)

Nothing to do with format. I personally found that the pov 3.0 docs had more
info on the structure of the language, examples, comments on effects of
options and pictures showing effect of values. This would be especially
useful re interior and media.

Although I did prefer the docs in one long file, made reading for interest
easier.

Ah! Finally, a challenge!
Of course, the object is so obviously composed of triangular elements that
asking for any concession is unfair :) And I did say you _hardly ever_ need
it.
Anyway, I accept. Just give me sec, I'll go find my math brain...

  We discussed the way we could no longer traverse the entire docs by paging

  I will have to take your word on this as I have only the current docs on
my present system. I *thought* it migrated into its present form mostly
unchanged, though, save for halo/media and any additional features over
v3.0.

  Ken and I also like to be able to do this. I use the Adobe Acrobat version
of the docs. I am able read the entire document from beginning to end (if I
wish) and it retains all section numbers and demo images. The entire
document can be searched for specific keywords and phrases, also, something
that might be difficult to accomplish in some of the other formats.

 I just retried the test and now score 27 (maybe 29 with doubt)

  I think question 62 is invalid by reason of it's wording. Csg's are not
primitives and are regarded as operations.

I'm using primitive in a different sense than you are.  There
are five CSG operations, counting inverse, but only three of 
them are primitive operations (as the term is used in Forth
programming) The other two can be expressed in terms of the 
three primitives, and one actually is expressed that way in 
the source.

I know that difference is actually the intersection with the inverse.

Am I on the right track with merge ?

merge {
 object1
 object2
}

==

union {
 intersection {
   object1
   object2 inverse
  }
  intersection {
    object2
    object1 inverse
  }
}

I've also only got the current docs now. That was my impression first time
I read the 3.1 docs. I read the section on radiosity yesterday. I'm fairly
sure
that the 3.0 docs had more than two pages on radiosity.

Is the pdf for 3.1 at www.povray.org ? If not where?

I think yours is an exclusive-or.  Here's what I came up with:

intersection {
  object {foo inverse}
  object {bar inverse}
  inverse
}

On the plus side, you get the points for wondering how it was done,
whether or not you actually got it. :)

Sorry for not answering that fast I have been busy the last days.
I would copy what Ken and Gail have said. What I have to add is that I
found the language declaration at the language description more
irritating than helping. I printed out both manuals and when I started
to do the 3.1 stuff I first tried to do it with these declarations at
the beginning of each section and really disliked them. They way the
language has been presented in the 3.0 docs I personally found much
easier (and that only a matter of the format).


All the Best,

Marc

What about the one that says you only use PNG format or the one that says you
always use the alpha channel?  I hardly ever 'always' do something in POV.  I
use colors.inc as a time saver, but by no means need to do so.

Then there was the one about making a patch for POV-Ray.  I made that one
patch a few months ago with changes to fix the problems with radiosity.
Later there were bug fixes made in those areas in the official version, but
I'm sure they handled it different, but I did point out the areas where the
problem lie.  Does that count?  Do I care?  I dunno, maybe.

Perhaps I'm just a casual user with hardcore tendencies. :)

  I can't remember what the differences are. I will check some CD-ROMs for
the v3.0 docs as I don't have them on my system any longer. If you can
recall offhand without having to turn it into a research project what are
some sections from the older doc that I can compare with v3.1 version
(dependent on whether I can find the older version laying around)?

> ...(and that only a matter of the format).

  Do you mean the doc's file format (.html, .pdf, Word, Windows Help) or
something else? I just want to make sure I'm on the same wavelength as
everyone else <s>.

Not the file format but the style actually. I know that it is typical
for programming language descriptions to describe the syntax in the way
it is done in the 3.1 docs. I tried to use it for a fast reference even
with parts from the 3.0 version I had forgotten (shame on me) but found
them not usable for me. Maybe you could add a small section that
explains how to understand them (or have I overseen such a part ... ?).

All the Best,

Does the "hardcore povrayer test" count for much? Should we care? 

I think it makes for some interesting trivia, but shouldn't be thought
of as some sort of important judgement on any POV-User's worth or
merit as an artist, craftsman, or human being.

You overlooked such a part.  See "Notation and Basic Assumptions",
toward the top of the document.

If we're speaking of the PDF version, the fact that the index doesn't
have hot links to the content is a minor annoyance for me.

(I don't know about the Windows version of the Acrobat Reader, but under
OS/2, it can be set to default to continuous rather than single pages,
so it *is* possible to page down continuously through the docs.)

I got 24, but have some questions:


#12-Not really, but I have ported the Photon Mapping patch to the
Mac(and found one very tiny bug in the code). I suppose that doesn't
count.

#19-I understand what it means, I don't know how it is calculated. One
point?

#25-does this mean "the only time you use PNG is with POV-Ray" or "the
only format you use with POV-Ray is PNG"? In any case, I use PNG and
TGA.

#31-Should this be here? I have heard of emacs, but I don't know what it
is, and I don't think there is a Mac version.

  Hi, Jeff. I'm using Acrobat Reader v4.0 for the Windows platform and I'm
able to click on a topic in the index to go to that particular section or
sub-section of the docs.

  My version of Acrobat Reader is set up this way although I don't recall if
this is the default or I changed something.

I support that opinion, and not only because I don't seem to get more than 10
(of course it's hard to resist to such a test because it's fun)...
Let's try to imagine such a test in the late 1880... The hardcore oil-painter
test... with questions like :
- do you know all the chemical formulas of all the pigments you use ?
- can you build a weaving machine so that you can make your own canvas ?
- what's the ideal growing temperature for linseed, so that you can grow some in
your backyard and crush the seed to make your own oil ?
- the thermodynamics of sunsets are a piece of cake
- can you tell the names of the ten Parisian brothels where you can sit down,
drink absinth and find cheap models and inspiration ?
- what's the average WHR (waist-to-hip ratio) of the brothel employees ?
- what's the average permanency of eosine ?
- what are the scientific name of sunflowers and irises ?
- do you hunt minks and wild boars to take their hair and make your own brushes
?
- do you have your two earlobes ?
- have you ever sold any painting ?

Yes. Software like this really needs several doc writers on each
topic. So much of the explanation is bound up in the way the
writer looks at it, their background and such. If the reader does
not have that background it does not make much sense. 

e.g. I was very familiar with the media scattering diagrams (two
points! for a total of three) before I saw them in POV but as to
the rest of the docs on media, I can't get it to work like it
"should" based upon my knowledge of scattering. 

The doc writer and I don't speak the same language. That is one
thing to get across to new-comers, don't be concerned if you
don't find the docs easily understandable, you are not alone.

There is a mac version (at least one). It's a programmable text editor
(*HUGE* understatement).

search at altavista (+emacs +macintosh) turns up some likely links. I
would imagine that much of what emacs can do mac emacs can't... but I
haven't looked.

  Well in defense of those who responded with their scores to this thread I
would say without exception they all offer aid to those in need. This comes
in various ways from simply answering questions in these groups on a regular
basis, hosting sites with tutorials, and spending time through private
emails helping track down that elusive problem. Personaly I think we are a
pretty helpful bunch aroung here. I know I personaly go above and beyond the
call of duty sometimes to answer questions around here and I am not alone
in that regard. I often hear comments that there is no other user group bar
none where one can recieve the level of help available here on the Pov news
server.

I found this test very funny and even the responses by those who made
it. I also think that Ken is right when he says that the willingness in
this group to help is quite great. See this test as a kind of joke. As
long as you like the pics you generate with pov nothing is wrong. I fail
many of the answers in this test and I don't feel minor in any way.
There's a lot to learn and for most of us only few time to do. Just take
it easy and have a laugh or two.
