As it says in the IRTC rules
( http://www.irtc.org/stills/rules.html#tools ):
----------------------------------------------------------------------
3.Acceptable Tools

     This describes what software and hardware you may use.

        b.Any rendering program is acceptable. The competition welcomes the
use of cheap or free software rather than packages only available to a few
professionals. There is nothing wrong with using such software.
----------------------------------------------------------------------

Likewise, in the Stills FAQ, ( http://www.irtc.org/stills/faq.html#q1.1.7 ):
----------------------------------------------------------------------
[1.1.7] Can I use a renderer besides POV-Ray? Isn't this a POV-Ray
competition?
     You can use any computer rendering program. The competition is hosted
by POV-Ray, but they do not make any demands on us or the participants.
[1.1.9] Can I use a scan-line renderer instead of a ray tracer? How about
one that uses some other rendering
technique?
     Yes, all algorithms are welcome. The quality should be equivalent to
modern ray tracers, though, or your image will compare badly with the other
entries. Note--we do not consider photocopying or paint programs to be
"renderers". The image should be generated by a computer, algorithmically.
----------------------------------------------------------------------


So yes, you can use Terragen for rendering your images.

Ok. thanks. thought I remembered something about it having to be raytraced,
and I'm pretty sure terragen doesn't ray trace. Thanks for the help

If there is a program that turns terragen "source" into POV-Ray source,
then it must be some kind of rendering tool, which is legal.

It's a bit contradictory that in the internet RAYTRACING competition ANY
renderer is allowed, even if it doesn't know anything about raytracing.

True, but considering the odd photo is submitted, I think demanding rt apps
only is going to create too much confusion and bad-feeling. I think that the
basic requirement of an algorithmic app is a good compromise.

Is a painting program acceptable if it uses some depth information to
calculate transparency and focal blur?

Depth info about what?

Okay, here's a scenario:

1. You paint a pic, using layers to which you can attach a particular depth
level.
2. You apply the focal blur based on this info.

It would seem to me that you could submit this to the IRTC provided that the
"source" included the picture from stage one. This would be the equivalent
of an image map being the bulk of a raytrace, and with correspondingly low
scores.

What you couldn't do is claim that the whole picture is
raytraced/algorithmised/whatever. No one could reproduce your submitted
picture without a copy of your picture prior to the focal blur. No algorithm
would exist for it.

  So if I paint an image map to use it on an object in my raytraced scene,
it's not a valid entry because the whole picture is not algorithmically
calculated?

???

(a) the quote you're replying to doesn't imply that. It only implies 
that if you paint an image map to use on an object, you cannot claim 
otherwise. (I hope this isn't controversial.)

(b) The post you're replying to covered this in a different paragraph:

"It would seem to me that you could submit this to the IRTC provided 
that the "source" included the picture from stage one. This would be the 
equivalent of an image map being the bulk of a raytrace, and with 
correspondingly low scores."

So, yes, of course you can use image maps. The more your scene is an 
image map, however, the more low scores you can expect to receive.
