Btw, I really hope you will not get a low score because many of the voters
think you cheated. That would be very bad.

Good news. These post-processing open a "realm of new opportunities" as they
say in commercials. This picture couldn't have been made without Megapov, and
I hope that it will be possible to render it in POV 3.5.
About the antialiasing, it was not such a problem here : in fact the bad
antialiasing could have been solved by using more demanding aa parameters.  I
had more trouble with the fact that focal blur is not totally compatible with
the "continue trace" option, since that means that the image had to be
rendered in one pass, or in several determined ones, but could not be aborted
without losing part of the blurring info. Right now, I'm not sure about
rendering a larger version: should I render smaller parts and glue them
together at the end, or should I wait for Megapov 0.5 and be able to abort and
resume the trace whenever I need it ?

This is unlikely to happen, since that the IRTC admins investigated the claims
and wrote to the people who complained that the picture was legit. One "proof"
of the image being touched-up was that the colour distribution of some parts of
the image was unusual for a povray picture. In fact, this may be due to the use
of semi-transparent, vertical planes. Now that the offending part of the scene
in available, I guess that those interested in this problem will be able to
check it out by themselves.

When 0.5 comes out (in a week or so, if all goes well), it will support
continued tracing with post-processing.  The problem with 0.4 is that the
post-process data file (postdata.tmp) is getting deleted when you stop the
render.  With 0.5, it will only get deleted when render has been completed.
In future versions, I hope to provide the user with even more control over
the post-process data file.

Haha..  *Most* POV-Ray pictures actually have an unusual colour
distribution to begin with (compared to reality or photographs.) I
wouldn't be surprised if your "unusual distribution" was simply the
somewhat rare look of a near-perfect rendering.    :)

Later,
