Let's put this creative effort used on sigs to use!
SHORTEST CODE CONTEST
Povray has many strengths. On one hand it can compete with some of the best
professional packages in the production of photorealistic images with
radiosity from the DXF output of a modelling program. On the other hand, it
IS amazing what the thoughtful amateur can do with just a few lines of ASCII
text. IMHO, this second quality of povray is a better "poster boy" for the
program and much more *fun*.
Many pov'vers like to celebrate this second quality of povray with
innovative signature files: making something really interesting with just a
few bytes of text.
Let's have a contest.
HOW TO ENTER:
Send an email to Greg M. Johnson at gre### [at] aol com with two attachments:
1) your submission in the form of a XYZ.pov file.
a) Please don't have any personal info in the image as the contest will
be judged blind. For example, if you currently have text that says, "BILLY
POVUSER", change it to "POV 3.5" or "POVVERS RULE" or something else.
b) Make it compatible with povray 3.5.
c) no #includes or #reads or #writes or #fopens are permitted.
d) MAX size: 500 bytes (arbitrarily chosen as twice the size of one very
competent sig file posted to p.g.)
e) have it end with //XYZ, where XYZ is a (hopefully) unique 3-digit
combination of your initials and/or numbers
2) an XYZ.txt file with
a) your name,
b) email adresss,
c) web page,
d) and any other comments you want to make about the image.
3) Please make the title of your email distinct from typical junk mail,
something like, "[Shortest Code Contest]"
HOW IT WILL RUN:
1) An 800 x 600 jpg of your pov file will be prepared.
2) A web page will be prepared where all of the image are visible, BUT NO
personal or author information NOR any data about the scene file
3) Participants will vote on their favorite five images (or some other
criteria). No one will know how many bytes are in the pov file during the
judging!
4) Prizes (in the form of praise) will be given to:
a) highest score
b) lowest bytes to still get rated as someone's favorite 5.
c) GRAND PRIZE: most efficient (some sort of formula of score / bytes of
text).
5) Contest submission deadline:
February 28th, or the first instance that we have ten entries AFTER this
date!

I mean scenes compatible with documentation but not working becouse of bugs or
changes ? For example I can prepare suprehipertransscene but beta from February
could destroy it somehow ...

Some examples:
- camera behaviour was changed but documentation not updated yet.
- something with isosurfaces'll change afaik
(I don't know how changes influence appearance).
- sphere sweeps differ from behaviour described in documentation.
- radiosity has bugs
- splines has bugs
- there are a few of blob bugs
- and many others from Known Bugs lists
There is a chance someone can discover nice 500 bytes long scene unfortunatelly
based on bug (without his knowledge), send it , and next beta can destroy his
effort.

sig files already have a max size: 320 bytes. Any longer and they're not
sig files. So if you limited participants to, say, 300 bytes (to make up for
word wrap issues) then they'd be making sig files.
Wow! 500 bytes. Whatever will I do with all that space?
Seriously, though, no theme or anything? It's easy to come up with an
attractive-looking pseudo-abstract image in a small number of bytes. An
image that actually has a point - like "neon" or "uses bicubic patches to
draw letters" or the below-included "spectrum" - is a lot more difficult.

Well, that's what makes it all the more interesting. It's a raw judge of
"quality" without knowing how small. If some bloke decides to do a fractal,
well maybe that's cool to some, and crap to others.

2 raised to the power of a relatively small integer.

In fact, it's better to use well less than 80 characters in order to avoid
line wrapping in quotes (I think that the recommendation is something like
72 characters in a line).

Signatures are exempt from that rule, because only lusers quote signatures. :)

Well, on one hand, the idea is to impress a newbie, (okay, me!). I think
having it open allows a wide variety of coolness: fractals, landscapes,
etc.. So I'd vote to keep it wide open.

Okay, is this covered by the requirement of "no includes"?

Yes, but as RP pointed out, it can be too easy to produce a nice, unstructured
abstract with just a few lines of code. Of course, they still have the option of
a nice fractal landscape that somehow spells out "POV 3.5".....

Hence, have judging so that people will pick out the coolest/best/ most
innovative.
Yet, wide open, so that people can see all the wild things that ARE
possible. If it's limited to text, really why bother at all?
(IMHO, yes povray's strengths do include the ability to make photorealistic
renders from Poser, and super-advanced DXF modellers. BUT if I were to see a
box of povray in the store, and what I saw was exacting detail of the Taj
Mahal and a note that said that image required 100Mb of meshes, I'd be
ho-hum, next freeware please. Seeing the VARIETY of what a genius can do
with a few lines is better, IMHO).
BTW: I'm just one opinionated dork. If someone more popular wants to
officially host it, by all means...

Have you rendered fractals3.pov in scenes\textures\patterns? It's half of

I wouldn't say text is really a limitation. Look at the various ways I've
found to express a couple characters. Look at Warp's sig.

With regard to fonts, etc., perhaps you should repost some rules to clarify this
issue. Ditto for subject matter (if this is to be set).
