Hmm, it sounds as though you just need to turn on anti-aliasing. Assuming that
you're using pov for windows, just select one of the AA formats for rendering in
the output dropdown, or specify +A 0.3 in the command line.
However, you say that when you render a sphere or other primitives, the "jaggys"
are not present, which is a bit confusing, since spheres are very subject to
jaggys.

Since he raised the "antialiasing levels", that means he tried that...
I am not a PoV-Ray guru, so I can't really help :-(
Perhaps Mark could post a simple model showing this problem on p.b.s-f, so
experts can take a look.

probably the best idea.

You should look at the final image, which is saved by POV-Ray to the
directory configured in Moray or POV-Ray itself (probably the same directory
where the scene file itself resides), with some image viewer.
Moray scales the image to the preview window, which can cause some
artifacts which aren't in the actual rendered image.

I think none of you guys read his second post (maybe it wasn't there, the
date suggests it was however) and didn't carefully read his first one
either. he used some incorrect terminology in the first one but still
described his problem accurately....
If you carefully read the first post you find that he reports the problem
only with objects from udo files. AFAIK (I don't use Moray) those are
simply triangle data files. So the problem is not with POV-Ray but with the
input data triangles. I don't know what options Moray has to smooth
triangle meshes, but I guess there is some, so maybe someone could explain
him how to do that?

Well, no, he says that

which rather implies that the problem is not limited to .udo's.

Hi all,
Mark again. Okay, I see you guys have replied to my original post, and
thanks. I have been wrecking my brain trying to find more info in the
tutorials/manuals out there, and I find that they all assume a little
understanding of raytracing. I have found out how to set the anti aliasing
in povray, and I assume that a threshold of 0.0 is the best one can get. I
rendered a couple scenes at this setting and it improved a lot, but I still
have problems with aliasing. I have also noticed that if I dolly the camera
away from the model it cleans up. I gather that the closer the zoom on the
object, the more it will alias. The scene I would like to render has
several close up views of objects (cone/torus merged, kind of like a dunce
cap with a moulding around the opening for the head) I also noticed that
when I have the threshold set to 0.0 the pixels that were aliased terribly
at no AA were now kind of "off the edge" or seperated from the model. It
looks as if particles of the model are coming off the edge slightly( I
don't think I am explaining this well) Sort of like the model was shedding
dust from itself. My question now is this: Is there a way to make a model
have sharp edges at a very close view, and if so how? If you need more
information from me to help, I will be watching this forum a few times a
day.
Thanks,
Mark

Perhaps if you post some sample images in p.b.i, we can better see the
problem you are having.

Since he is posting in povray.newusers it can be worth to explain p.b.i means
povray.binaries.images group designed for posting images.
