Excellent floor!  Where's the reflective sphere, tho?


Seriously, looks great. But what are the dots outside the windows? Looks 
like birds or netting, running off the light posts? Artifacts? Or 
intentional?

The thickness of the outer walls, overexposed from the bright daylight?

Well, without height references such as people figures perhaps it does.  Its
POV-Ray camera is so much closer to the floor than the ceiling that that
reaction is certainly understandable.

Yup, the capitals are most familiar indeed.

I remember seeing that before.  I tried having the media for light beams
turned up that high, but it didn't look quite right, especially since the
"windows" have no glass, so the indoors air has to match the outdoors air,
and it couldn't be that hazy outdoors.  It works great with his image of
Justinian's church though (which is a rather awesome rendering IMHO).

That's interesting and very good work...  Like me, he seems to give loops
heavy useage for the purpose of constructing with patterns of virtual
building blocks, kind of like building with virtual Lego.  POV-Ray makes
that so easy, and is why POV-Ray does well with Classical architecture.  His
details are generally so much more intricate, complete with egg & dart
trim.  If my machine had more RAM maybe...  View-based detail management to
save on RAM useage is a goal of mine.

Thanks for the links!

Exactly; the thickness of the window frames.  I used a marble pigment which
got massively saturated.

There is an color abberation artifact, though, along the roughly right third
of the end upper window, with a round edge and what I've decided is a bird,
not an error or artifact, at where the color abberation's left edge
intersects the bottom of the upper end window.  I didn't create a bird
there, but that's what I'm saying it is. ;>  It was media useage that led
to it, not radiosity (or maybe the combination, but radiosity use alone
generates neither the color abberation nor the "bird").  There are some
versions I've made where it's much more noticable.

Here's another example from a different angle (also at 70% JPEG quality
setting to save server space) showing the media-related lighting error I'm
getting.  Not sure how to solve it...  Getting into a different question
now I guess.

I must be getting tired...  I'm really not trying to see how many pics I can
put on the server...  I'll try one more time to show the _different_
view...

Stunning work.  I especially like the coffered vaulting.  Now where are the
pools of water with steaming media?

Thanks.  The ceiling (including barrel vaults) is made, basically, of
multiple layers of a rather large amount of fairly simple trigonometry.  It
took me awhile to figure out how to do the crossvault "seams" (crossovers),
and getting everything to line up decently enough took some trial and
error.  The earliest models used CSG, but it looked plastic and utterly
fake, like everything was covered in a single sheet of formica (and took
much longer to render than using a building block approach).

That would be the caldarium (hot bath, a Turkish bath of today) - haven't
depicted that yet. ;>

I read a quote from back then that there was so much gleaming marble Rome
looked rather like it was covered in a carpet of snow when viewed from a
hilltop (except of course, I would think, for nearly everything being
roofed in brick roofing tiles, and the significant fraction of the city
consisting of squalid tenements wouldn't have looked exactly gleaming from
any distance).  But for a denarii (about US$0.25) even the poorest of
Romans could spend the day in the greatest general health clubs the world
has ever seen (and also likely the noisiest from other quotes I've read).

At some point I'd like to add a frigidarium (cold water pool, essentially a
modern public pool) to its left, with its own elaborate wall based on the
Thermae of Diocletian, but print-grade renderings at least (3200 x 2400 or
higher) require such detail as it is that POV-Ray alone (initially at
least) uses 3/4 of the 1G RAM my machine has.  I do _not_ want to try doing
a rendering with the machine heading into swapfile land, slowly thrashing a
HDD.  If I can figure out how to automatically minimize away-facing details
based on the viewpoint and zoom chosen...
