I've run the short code and the fractal competitions, see
http://astronomy.swin.edu.au/~pbourke/povray/scc3/final/
http://astronomy.swin.edu.au/~pbourke/povray/povfrac/final/
Are you sick of these competitions or is there still interest?
If the later then how about another in the near future, what about these options?
1. Limited geometry. eg: Create a scene with no more than 10 objects from
the following list: sphere, cylinder, cone, box.
2. Special geometry. eg: Create a scene using only one high level primitive,
but as many of them as you like, for example: a supershape.
3. Create a 3D scene which when rendered from a particular position forms an
image that tiles the plane.
Feel free to suggest others.

The third suggestion sounds interesting.

Like it. Texturing/lighting could make all the difference. The sharp
edges might be a limiting factor.

Not sure what high level primitive means.

Whoa! Sounds tough. But radical.

The common element between contests is that they are relatively short,
simple, around a single limiting idea, that has more to do with process
than subject?

I dont think this is best idea, it is too hard without little pre-
processing, even AA want work a bit strange around edges

"High level" meaning no meshes, isosurfaces, blobs, etc?
A combination of 1 and 2 would be interesting. Create a scene with just
one scene-level blob, isosurface, or mesh, and nothing else. Manual
specification of data would be allowed, but no modelers...size/time
limits would encourage algorithmic scene generation. Other shapes would
be allowed for things like the object pattern, but not as actual scene
objects.
A practical use competition...try to come up with a useful tool, the one
voted most useful wins. Maybe have two parallel competitions, one POV
only, the other allowing external programs, Java or C++ for example.
Volumetrics. No directly visible objects, the entire scene must be
composed of shapes only visible through interior attenuation or media.
Maybe refraction, as well...it'd allow some good photon scenes. And
maybe some severely restricted visible objects, such as a ground plane
or finite sky_sphere.
Optics. Mirrors, prisms, lenses, etc. Nice caustic patterns, simulation
or illustration of specific optical effects, and so on.
Radiosity only. Not much description needed...
Environment. Basically, come up with some good surroundings that'd make
a good HDRI map. The focus of the scene would be a collection of objects
showing the environment off through reflection and radiosity, and should
probably be standardized to compare the environments more effectively.

This is interesting. I once done a animation (my first real pov-job)
"matrix" that worked that way. It was suprisingly fast rendering as for
media based scene.
But, I thing that to make something realy interesting users have to have
quite strong computers, and it might be a problem to some users.
On the other hand, it would motivate more usesrs to learn madia, with are
realy very powerfull but meany users dont use them (media can seem quite
hard to learn at first). So, maybe for even next competition?

IMHo this idea is *BEST*
- make that way environemts would be very usable (especialy if someone will
make a .hdr output format support, or is it already supported?)
- pov made images could be usefull by other (non-pov) artists, it could be
a good way to promote PovRAY
- no special limitations = meany users will participate
- a good field to create photorealistics images (but not limited to them)
I say it rocks, lets do it Paul :)
Btw - maybe give much longer times? I.e. contest will start in about 1
week, and we woud have a full month to create images. That should allow to
create realy quality images.

I like the idea of a competition for programs that assist in making pov-ray
scenes. I'm sure a lot of people have knocked together quick utilities
(especially when making animations) that this competition would encourage
them to tidy up and release.

As already said the last time, i'd not exaggerate the frequency of those
competitions, designing a good scene takes some time so unless you
explicitly want a short time contest some longer time for the
competitions would be good IMO.
The idea to restrict usage of objects to certain types is an interesting
concept, the french 'Defis' contests had one with only boxes:
http://empirium.free.fr/defis/def.php
A contest which only allows one mesh or one isosurface would be
interesting although the latter surely would lead to exorbitant
rendering times (ABX could send his IsoCSG teapot...)

Those were fun. :D I'de like more ... but I don't want
you getting burned out by running them!

interesting.

yeah, that could work (goes to read what a "supershape" is in
the docs)
1) Hmm: how about just isosurfaces? I'de have to skip that
one for CPU reasons.
2) just prism objects. That I could do :)
3) just the fractal object. I actually misunderstood
the last contest to be this. :(

This last might be too easy to be a contest. I believe there is
an include file out there that will do it for you automatically.
I think Chris colefax wrote it but I'm note sure off the top of
my head.
>Feel free to suggest others.
I have a few. I hope this is not too long:
1) Image re-use. What I mean is, the contest would
specify a picture file (or two?) and the point of
the contest would be to use re-use that picture
in a new render. You could use them as pigments,
you could maybe even UV-map them. Height field
would be an option. using functions to recolor
the pictures would be creative. Since the picture
file would be created/chosen by the contest organizer,
there would be no copyright problems with it.
2) finish / remix a scene. The contest organizer
would create a partial scene in a .pov file. and
put it up on the web. Contestents would download this
theme and edit their copy. Some sort of limit
for the amount of changes should be done but I have
no idea how that would work.
