I'm thinking about writing my own renderer, but it would be vector graphics
based. How does the Internet *Ray*Tracing* Competition feel about that? The
rules state work must be produced using a 3D renderer, but there's no mention
that it actually has to trace rays.

I just want to confirm that no-one makes a distinction within the IRTC as to the
exact means of rendering 3D things.

Oh, and while we're on the subject, if there's no restriction then why's it
called the IRTC? Surely it should be the I3DC or something ;)

Well, they permit Blender entries, and Blender isn't a raytracer. There have
also been numerous entries using the 3DS scanline renderer, and Terragen
entries, which I think uses z-buffering.

Just rolls off the tongue better?

Actually, this is covered in the FAQ:

http://www.irtc.org/stills/faq.html#q1.1.9

[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.

I missed that when I checked the rules!
That puts my mind at ease. :)

Though the choice of name still seems a little odd...

Thanks

I wasn't sure if they all had ray tracing options. Though now you mention it I
do recall some people noting that their 3DS entries were using the scanline
renderer.

Could be, but I'm sure there must be some sound historical reason or something.
Or the could call it ICGC, or even the Internet Rendering Competition, but that
acronym would get confusing :)
