This is the type of problem I am having. The model is ONLY there to show the
problem, not a real model I am making. Please don't judge me for the model,
okay?

I really think this is a terrible model. Please don't post any more things.
I think you're one of those people with 2 eyes, 1 nose and some arms and
legs attached. :)

(just kidding of course (to make sure))

For Anti-aliasing look at:
1) AA level (+An.n : +A0.0=best,slow)
2) Sampling methos (+AMn : 1 or 2; +AM2=best slowest)
3) Recursion level (+Rn : +R3 standard, > better,slower)

If you have the patience try +AM2 +A0.0 +R4

see section "5.2.6.4  Anti-Aliasing Options"

Thanks, and will do...I haven't read anything about the sampling methods and
recursion level...I know sampling...now I gotta learn what recursion is :)

See
news://news.povray.org/3CDA721E.A3091134%40luxlab.com
or if you prefer another protocol:
http://news.povray.org/povray.binaries.images/24275/

It's not a newbie problem. It's a general problem of how to sample
a 2D signal. You may also want to try +am1 +r<R> +j<1.5xR>.
It trades gridded artifacts for noise: http://luxlab.com/tmp/aa_noise.png
