Here are some guidelines that should help you to create a suitable entry for the competition.
In contrast to the competition rules they are not binding.
The files to submit
The rules require you to submit various information in addition to the actual
image. It is recommended to make descriptions informative and elaborate. The additional
information (except the author identity) will be made available to the judges who
will use them to better evaluate the entry.
You are required to list all tools and data files used for creating the image. It is
important to give correct information here. You are allowed to use any tool you want for
modeling, texturing etc. but if you neglect to mention this you will be disqualified.
If you use 3rd party data files like meshes and textures you need to take care of the
licensing issues. You need to obtain the rights to use those in your image when they are
not free to use. The winning entries will need to submit the complete source code but
this is only for screening purposes and usually does not require a special license. If
in doubt ask the owner of the data file.
The main purpose of the rules for the image itself is to ensure a high and comparable
quality. The judges should be able to assess the author's work mostly by viewing the image. Therefore
there is a minimum size and you should take care of not using too strong jpeg compression.
In addition we also want to make sure that the scenes are detailed enough to look good
when printed in large. Therefore we require the entrants to submit two detail views. You are
of course free to render the whole scene in large but since this can take a long time with a
slow scene we only require two small views. To render the detail views you can use POV-Ray's
+sr/+sc/+er/+ec options but note that the images generated by those are not
readable by most imaging programs. We prepared a unix shell script
to turn a partial render in PPM format into a correct PNG image. You can also use the
following include files:
Subject: ZoomIn include file
Date: Sat, 11 May 2002 17:40:53 -0400
which allows to set up a camera for a partial render. This has the disadvantage of not
allowing use of vista buffers because of non-perpendicular camera vectors and it only works
with perspective cameras. Since the purpose of the detail views is to show the detail level
of the scene you can also just change the camera manually to point at the right region of
the scene and reducing the camera angle as required. The small difference in perspective will
not be considered critical.
If you submit a larger render this will be scaled down to screen size (1600x1200) for
judging and the large version will be used as additional information for the details
just like the separate detail views.
The image has to be submitted as rendered without modifications. A lot of people might
find this restrictive so you can submit an additional post processed version if you want
to but the purpose of the competition is to feature 3D renders made with POV-Ray, not 2D
We allow use of custom modified versions of POV-Ray but be careful when making use of
this. As the rules say you have to make sure the scene can be rendered for verification
in case your submission wins. Therefore you will have to ensure a sufficient quality of
your patch. Use of extensions that are still buggy, platform specific or otherwise
problematic would not be recommended. Also make sure your patch complies with the
POV-Ray license. If you intend to use a patched version it would be a good idea to
discuss it in the POV-Ray newsgroups.
