I haven't really done anything "complex" - I just fiddled with some textures,
tidied up some code to hopefully keep some of the memory usage down and speed
things up, and tried to get most of the code into a tab-indented hierarchy so I
could follow all of the nested CSG operations.

Well, this is where I learned it all - and I probably couldn't have learned as
much as fast without all of help and suggestions and examples and debugging
assistance from dozens of people.

:O ? What errors and what lines?

Line 354: expected map file spec, string identifier found instead.

Could be because I am using the 3.7 version. Of the 3.8 version, I only have the
32 bit version (pvengine32-sse2.exe) but not the 64bit version. Do you have the
64bit version and if so, can you send it to me? Was there any 64bit version?

If not, I will go ahead with the 32bit version.

Pretty sure I have the 64 bit version.   But I'm running Dick Balaska's
QT-POV-Ray port of 3.8 on Linux.

I think all you need to do is prepend png or jpg right before the quoted
filename and it will be fine.

Though I suppose we might play with checking the version number, and then:

y.org%3E

just for experimentation purposes.   ;)

I only left it out because I remembered:

Turns out that the EXE file I had and believed to be 3.8, is in reality just one
more copy of 3.7.

Is there any URl for the download of 3.8 alpha? I know that the development of
3.8 had been plaed back into the body of 3.7, but hope that someone still has a
64bit version of the 3.8 executable.

Up to now I was not been able to resilve the error problem with 3.7, and my head
is smoking.   :-(

Fffiuu.... I truly had not been aware of the tremendous size of those 
things! Learned something. ;-)

Yes, it is amazing. Those ballistae came in all different sizes. But there were
not only those XXL sizes as depicted here, there were also the smaller sizes
made to target humans.

And beside ballistae, there were also cheiroballistrae and scorpions especially
to target enemy soldiers.

All these artilleries were able to load stones, arrows, and special ammunition
like the glowing coal loaded fire arrow, or the harpax for naval combat.

http://news.povray.org/povray.beta-test/thread/%3C5c6b6863%241%40news.povray.org%3E/

which points to:

https://github.com/POV-Ray/povray/releases/tag/v3.8.0-alpha.10064268

Weird.  Maybe someone else running a 3.7 Win version can try to render it and
see what they get.

It's true that the Romans of the time where thinking big.
That ballista was made to take out the opponents engines, medium 
fortifications, ships and scatter troops.

Just imagine keeping your formation when 75 Kg balls of rock are flying 
at you and bouncing around...
