I think the original spirit of the competition always allowed that kind of
layer-rendering, even if the original authors of the rules never thought on
this possibility. It was just some of the judges and entrants who thought
this was forbidden, but for me it is clear that anything affecting equally
all pixels was legal. Fortunately, I've a copy of the Rules and FAQ, and
specially the FAQ seems very clear to me:

In any case, to make it really clear that it is allowed, the new FAQ could
use an entry very similar to this old one, just replacing "parts" by "layers":

?? "Ray tracing" isn't a synonym for "Povray", or even for "free
software" you know. Most commercial packages include a ray tracer
and some very high end professional renderers are ray tracers
(Mental Ray for example).
Moreover, the "ray-tracing" in IRTC has always been taken to mean
more "3D rendering" than strictly "ray tracing". IOW a valid image
is an image that was created by the computer from a 3D model using
3D algorithms even if those aren't strictly speaking "ray tracing".

Well, I was replying to comments already made here, like:
"I think ultimately most considered IRTC to be a
coding contest..."
there is a wide variety and many of the winners were using modelers. I could
make a long list.

That's OK. My history goes back quite a ways (back to the POVRAY forum
on CompuServe) and that's my recollection from that time. I haven't kept
up with it.

Neither could I, truth be told, at least not a very complex image.
That's why if you look at the history, you'll see no submissions from me.
At the same time, if you look at some of the images Shay (I believe) has
posted in p.b.i, I understand those are all pure code, and he's adamant
he's not a coder (again IIRC).

Correct, that and I haven't felt that anything I've done was particularly
noteworthy. I tended (in the past) to do just simple geometric shapes
using Moray or (more recently) single objects with Wings3D or Blender.
I've also had very little success is coming up with textures that I
thought looked good - but I haven't had the time to spend to learn how to
do better.

Or it could be sticking a sequence of 3D renderings side-by-side to show a
sequence of events. Or it could be changing everything to sepia color. Or it
Maybe we should apply the same logic to the problem of post-processing. If what
it done overall is not sufficiently masterful in 3D then it just gets bad
shades of gray. Is that reasonable?
Submissions are expected to primarily demonstrate and document the use of 3D
software. Scores are awarded based on artistic, technical and conceptual merit.
That keeps the work about 3D, does not dictate methodology or tools. But allows

How about this:
Submissions are expected to primarily demonstrate and document the use of 3D
software. Scores are awarded based on artistic/conceptual, technical merit and
quality of documentation.
That puts us back at three scores per image.
So there you go! Problem solved. Right? Something missing?

It is the Technical rating that gets to me. Being a Pover, albeit I use a
modeller. I feel that I can score Pov scenes on Technical but how can I rate
something that uses software I don't know about?
Also a technically simple scene can look great so concept is important too.

wash. The artistic score cancels out the rise in the conceptual score. Why or
or are we dictating that all images must be beautiful to win?
From: Stephen
it would be like comparing apples to oranges when you are judging technical
where someone has really done something extraordinary, say created their own
rendered.
would be something like:
must be made in PhotoShop and be mostly red with small black specks. The
In the end we could vote on how well people followed the instructions and the
round would be filled with red apples that all looked more or less the same.
Standardization may make judging easier but at the same time destroy the
diversity we all love in the competition.
I have thought for a while it might be less of a problem if there were only one
score given which would account for all of the positive aspects found in a
side is that you would be less able to know what aspect was liked or disliked
some other aspect no one considered that might show up in a round. For example
add anything else in the way of concept. So maybe in a round like that we might
Sure this is silly the next thing you know we would have dozens of aspects,
things you might say are being accounted for now but lumped under another
clear.
Personally I think I would like to make a spreadsheet with two dozen qualities I
look for. Judge each entry on each topic and give them a total as the score.
It seems now that there is more debate about scoring than what should be in the
competition. Should this be considered and endorsement of my first sentence as
the sole criteria for what constitutes an acceptable submission?
From: Michael Hunter
Then the bit about judging:
Scores are based on a variety criteria which may including but not limited to:
originality, difficulty, beauty or expressiveness and documentation.
I think this is how things have been judged anyway but this puts it in writing
and acknowledges the imprecise nature of voting.
