I need some help to avoid jagged lines.
I prepared a scene with a lot of straight lines that are modeled as
cylinders with a very small radius.
Rendering this scene I get very jagged lines. I tried to change
antialias parameters, antialias_depth, Jitter_Amount. Although the
results look better I don't get a satisfactory result.
I hope somebody can give useful suggestions. Thanks!
Herman

Sometimes such problems just can't be fixed by pov. The general solution in such
cases, iirc, is to render the image at twice the size you need without any aa,
and then reduce the image size using a suitable graphics application.

Or you can try a slight focal blur.

Which is equivalent to rendering with +AA0.0 (AA threshold of zero) and +Rn
(where n is the number of times to multiply the image size) except that you
can also use jittering with this method.

Can you elaborate on this?

To get the best antialiasing you should use the antialiasing parameters
"+a0.0 +am2". For an even higher quality, you can increase the +r value
from its default (which I think is 3), for example with "+r4" (or larger).
This gives you a very high-quality antialiasing even when there are lots
of sub-pixel-sized details in the image. The drawback is, of course, that
it will take enormous amounts of time to render.
(And no, using a value larger than 0.0 for the +a parameter will not help;
it will make the render faster, but its quality will not be good if there
are are lots of sub-pixel-sized details.)
