Yes, the novices submit one image, the rest submit two.

David would have to enter the Advanced class, hopefully people
like him would be disqualified if they tryed to enter that
complicated stuff in the novice class.

Indeed.  I've done some scenes (not for IRTC) which are fairly simple in
concept but very slow to render, so an extra image would increase the
total time required significantly.

Cheers, PoD.

	If you don't mind my saying, I have been thinking of testing the
envelop or pushing the loophole to see what happens. I can make
PS sit up and beg and I have been thinking of exactly that. Do as
much as possible in PS and then run a two minute render and see
how it fares. 

	My original interest in POV was to do things that are hard in PS
and got addicted. No more struggling with textures just crank
them out. This time (six foot cockroach) I got a compliment on
the wallpaper and I stated that it was created in PS. 

	Anyone else feel like testing the limits? As long as it crawls
through a renderer at some point it appears to be acceptable. And
then renderer appears to mean that the package uses the word
render in its sales brochure.

	The following took about 10 minutes (start to finish) with
photoshop. 

http://giwersworld.org/artii/nraol.jpg

	This one about an hour total including modifying the psi
charcter

http://giwersworld.org/artii/psicorp.jpg

	It takes some hours in hell with PS and the plug-ins to learn it
and I have some thousands of those hours. But I get feedback on
my attempt in a couple seconds not hours regardless of
complexity. I can gat a new trial and error faster than I can
change the code in POV. 

	And anyone try this in POV

http://giwersworld.org/artii/perspec.jpg

	and that was just noodling around with one of the plugins. I
don't remember how long it took. 

	So that is the difference to me. 

	Now look at this one. 

http://giwersworld.org/artii/pattack.jpg

	The pyramid and the flyers are POV. The rest is PS and plugins.
The benefit I first expected from POV is that I can get different
perspectives and viewpoints on the POV parts trivially. But in PS
I cannot move the ground plane without planning way ahead to want
to move it and duplicating it without planning to do so is
essentially impossible. But this was also just playing around one
night, maybe a couple hours with a dozen variances and no
planning at all. 

	OK, I have bored you and bragged but those are examples of the
differences between POV and raster rendering. 

	So yes, once raster rendering is considered the same as
raytracing we might as well shitcan POV usage in the IRTC. And PS
5.x has added animation features such that if characters don't
turn or the camera does not change distance POV is out for that
also.

	An outstanding suggestion! It would wipe out the raster
renderers completely.

	Not impractical as the famous last words of someone who doesn't
have to do it. 33.6k is finally falling so 56.6k can become the
most common dialups so switching to doubling (by the time it is
done) should not harm the download time per voter. The second can
be smaller size and lower quality as it would just be a proof
against raster rendering so both storage and bandwidth are not
really harmed. 

	But then it gets complicated and technical requirements to
english speakers often fail. Language barriers are still real
barriers. But I did just find a dutch site yesterday announcing
the dutch version of the site would no longer be updated. The
common internet language wouldn't bother me if it were Italian or
Swahili -- only if it were French. Just wish there were only one.

	And who is a novice? asked the doubting Pilate before the
