Just wondering... Several people here have signitures consisting of
compacted POV-Ray code. Has anyone ever actually tried *running* this stuff?
I just did, was utterly unable to follow how the heck it works, but was
highly impressed by the resulting graphics!
Just a thought...
Andrew.

Well, some time ago (a year or something like that?) there was a boom
of making compact pov-signatures.
I think that the idea started from me using a compact signature written
in C and then making a similar with pov code (or was it someone else who
made it in pov code first? I can't remember).
At that time it was a common practice for me and a couple of other people
to take the signatures of other people and shorten them even more (without
affecting the resulting image in any way, or at most only slightly
noticeably). Some of the shortenings were really impressive (eg. something
like from 5 lines to 2 lines).
Usually shortening has the side-effect of making the code even more
obfuscated, so it has two advantages.

A good exercise is to format nicely these signatures, then to understand how
they work. Renaming variables may help :-)

I believe the origin of such craziness is from "The International Obfuscated
C Code Contest" <http://www.ioccc.org/>
Now, most programming languages has some obfuscated code showing :-)
Even Perl, which is quite obfuscated in its natural state ;-)
See also the "Name that programming language" (approximate citation) from
the Off-Topic newsgroup.
> PS. I gotta get me one! :-|
Me too :-) I just have to start working on it, creating a short scene then
compressing it.

I think the very *existence* of the IOCCC is a statment about the mentality
of C programmers... (Bloody weirdos!) I keep having these nightmares that
one day I'll wake up and discover I've become a C programmer...
(Of course, programming in Java can hardly be considered sane either! But
it's mainly the class library that's bizzare, not the actuall language...)

Oooo... Can't stand Perl!

Mmm... with my years of experience of fractal geometry and iterated systems,
_surely_ I can come up with something ;-)

You are aware of the language POV-Ray is written in, aren't you? And
that probably the only group on this server with a higher concentration
of coders and patch writers is povray.unofficial.patches? ;-)

I think C++ is an even better example. There you have an ugly library
*and* a language that you can do all sorts of bizzare stuff in.
Perl is more obfuscated in normal use, but you can't do as much. Either
one can be reduced to something that doesn't resemble anything
human-readable.

I hate Perl. I can't get it to work at all. It's nasty. I've had more sucess
with C, although it's just too dam hard to read... (I was actually trying to
write an object engine... *you* try manipulating pointers to pointers to
arrays of pointers to functions! Very hard when you don't have any sort of
manual ;-) Not to mention the danger of leaving pointers dangling... I
wouldn't *dare* try it with anything other than Linux 8-D (But then... I've
never heard of a C compiler that works on anything but Linux. I'm sure such
things must _exist_, but I've never come across one...)

Everyone does. Post the results in p.g. and watch the sparks fly!
It's quite interesting to find out the tricks other povers will come up
with to compact your .sig even more!

You are probably making things too difficult. And function pointers are
very weird at first, but they will make more sense eventually.

Huh? The vast majority of C compilers were for non-Linux platforms. C
itself existed long before Linux, and is as old as Unix (it was created
to make developing Unix easier...the first Unix was written in PDP-11
assembler, but was rewritten in C two years later, in 1973). One of the
main goals in its design was portability.

As I said guys, I know that compilers must _exist_ for other platforms (what
with the number of C programmers they want for Windows projects and so
forth)... Actually, now I strain my brain a bit, we used a Borland C++
compiler at college (DOS-based thingy - but then, we were using Win 3.11
anyway!) But let's face it, you'd be hard pressed to find a Linux distro
with no C compiler; how many Windows install CDs have one? ;-) How many
*free* ones are there? Linux (and probably UNIX) is just _built_ to compile
C; Windows needs more effort. (In many other things too... ;-)

That's just because the distributors bundle one with it. The C, C++,
Fortran and Pascal compilers that come with most distributions are
really separate pieces of software.
Some Unices do (or did) not come with a bundled C compiler.

GCC is available for many platforms, including Windows.

No. Just because most Linux distros also include an older version of
POV-Ray doesn't mean that Linux was made for POVing.

Indeed. follow-ups set.

Windows itself is written mostly in C (at least win3.x was; probably also
win9x used a lot of the same C code; currently windows is probably written
mostly in C++).

Unix is user-friendly. It's just selective about who its friends are. ;)

There was a company named "Microsoft" that came out with a C compiler about
15 years ago for DOS. I don't know what's happened to them since, must have
fallen into obscurity...
Based on my experience, and this is not meant as a criticism towards anyone
specific, overly complex or unreadable C or C++ is the fault of the
programmer, not the language.

Idea of heaving POV sig is not only to have a nice image there but also to put
something to recognize who is owner of the sig. So could be nice to include
nick there. Not talking about the cryptic nature of signatures :-)

Sorry to respond after more than a week, but this is a matter of life and
death... The thing is that yet another superfluous character remains in Pyry's
nice and short sig. Being a very compulsive person, my rest of days would have
had mere shallow meaning if this issue was left unattended.

Thanks for shortening my signature, but I can't really use it because:
-It doesn't have my name or anything about me on it.
-Now that you people have shortened it, it isn't really *my* signature and
IMO it would be wrong to use it.(You might disagree, but this is the way I
feel and I think that what is mine must be made by me.)
But thanks anyway. =)
I'll keep on POVing and maybe one day I'll come up with a new signature.
