That bounded_by gives you no benefit; try computing a snugly fitting box 
instead.

Difference and intersection benefit most from manual bounding, because in many
cases the auto bounding box can be orders of magnitude larger than the result of
the CSG operation. I once wrote a curved-brick macro that achieved something
like 10x speedup once I sorted the bounding out.

Meshes will be faster (non-csg meshes, at least), although presumably that would
mean more work for you... :-(

I seem to have resolved most of the bounding image. The following test 
render only took about an hour to render. Not bad.

"Bounding issues", rather. Also forgot to mention that I replaced all 
the cylinders, spheres and so forth with meshes. However, I wasn't able 
to detect any performance improvement in this particular instance.

Ack! I tried rendering again this time with radiosity, the atmosphere 
and so forth turned on, and render times went through the roof!

I'm getting to be f*****g tired of having to deal with all this 
low-level stuff! I want to get back to the creative side of the project!!

There always comes a time when you have to deal with that stuff  :-)  Be 
patient. Just don't let it eat you up.

I'm also considering a shiny gold Kepler Poinsot solid and an 
"historical" spacecraft, both from the Object Collection.

Nice one! There must be an artist living there.

Here are results of some test renders showing the effects of turning 
certain features on/off.


Legend:

rad   = radiosity
atmos = atmospheric media
fit   = the method I used to bound the buildings in boxes
qual  = the quality of the textures & materials
     0 = random pigments, no finishes, no media
   1/2 = regular pigments & finishes, no media
     1 = regular pigments, finishes, & media
seconds = the time elapsed from start to finish on a 2.4GHz single-core 
Celeron CPU with 3GiB RAM
pov   = POV-Ray version, either 3.6.2 or 3.7.0 beta 37a

Two more test renders. After 18 hours 28% of the image completed, and 
then dropped to the PPM range instead of PPS when it got to the crowded 
bits.

:(

Another test render. I seem too have eliminated a few more bottlenecks. 
This one only took 15273.62 seconds with all features turned on except 
the atmospheric media.

Forgot the image. ;)

Anyway, the atmospheric media seems to be the main remaining bottleneck. 
Not sure how to make it perform faster.
