Not everyone uses the Windows version.

Good point, on both counts.  I hadn't thought of that.

With the script in its current form (which I will upload a newer
version tonight unless I get some bug reports/idea suggestions to work
on (hint hint :) ) one can do the following:

1. Render a single file or batch render all files in a directory tree
2. Convert the output image(s) to JPEG or GIF
3. Create (a) thumbnail(s) in the corresponding format
4. Tune the JPEG/GIF compression/color depth for the image/thumbnail
5. Replicate the directory structure of the input directory, eg:

Input directory is /usr/local/lib/megapov/demos/
Output directory is /home/peter/scriptus/

The script will create:

/home/peter/scriptus/thumbnails/iso
/home/peter/scriptus/images/uv
/home/peter/scriptus/streams/uv/tweaked_by_me

etc. and will place the corresponding files there.

6. Auto-continue render if raw output file found
7. Only render files if corresponding JPEG or GIF not found
8. Delete the raw output file after rendering

and more.

I am currently working on a sort of a database for the renders. The
other thing I am working on is a CGI script which will automatically
generate a web page with previews, individual stats, render
histograms, global stats etc. The ultimate goal is to have a system
which you can give a motherload of work, go on vacation an monitor its
progress online. Well, maybe not :) but it sure helps when you have a
blind Linux box. The bash scripts which my brother and I wrote did a
good job in rendering the MegaPOV sample scenes, but they can't do
much more than that.

Enough blabber, back to coding :)

Hey Peter,
What is Perl ?

To quote Larry, the author of Perl,

"Perl actually stands for Pathologically Eclectic Rubbish Lister, but
don't tell anyone I said that. "

"The Perl motto is ``There's more than one way to do it.'' Divining
how many more is left as an exercise to the reader. "

"The three principal virtues of a programmer are Laziness, Impatience,
and Hubris. See the Camel Book for why. "

:)

It actually means Practical Extraction and Report Language. It is a
script, interpreted language (like POV :) ) which is very suitable,
among other things, for manipulating text streams.

Here comes the next version (as if anyone cares :) ). The
--replicate-tree option now works. Return codes are handled so if you
cancel a render in a batch the script will know and will not try to
convert the output file nor delete it. MS users might have problems
with the / vs. \ pathname separators but that's what beta testers are
for. As of MacOS... well, I have no idea how to execute a command line
on the Mac, so there. No MacOS support.

I am working on a few other things. One of them is an option to zip up
the stream files. The other is of course the CGI part which will
analyze the whole mess and generate a master page with thumbnails and
links to individual pages with various stats (not only those reported
by the renderer). I will be glad if I get some feedback before I hit
1000 lines of code.

Thanks for your time.

A very educated answer if I may say so, but how do I use it? An enlightening
link?

Oh drats. Darn copy-paste. Line 549 should read:

print "File $Output_Directory.$Subdirectory.$Stripped_File_Name.ppm" .

with the quotes and the ending period and all. Sorry about that.
