<< you will find this picture in the IIB/Threads/Additional-Directory >>
This didn't seem to make it the first time I tried sending (12 hour
or so again) so I'll send it again. Sorry to everyone if it did make
it thru the first time and I just didn't get it into my box.

To MikeH, Charles, Jason, anyone else who might have seen this and had
similar questions... :)

Wops, forgot that! Sorry for the large download time, previous
renders didn't have the green lights in it, so the size was a lot
smaller with no compression (smaller colour pallet)... Didn't even
think to check the size.

Actually, I think your description of this is a lot more fun than the
real thing. I've been accused by certain people (read: mike B!) that
my pictures are far to dark.. this seems to be true for more than just
the one person! I have incredible problems adjusting my monitor to
the correct brightness, which means I have an equally hard time
boosting my lights up to the correct intensity level. =P. Anyway, to
see the whole effect either turn the brightness up on your monitor or
increase the brightness of the picture by 20-30%... I'll boost the
lights up even more for my next render.
The green lights are, in fact, green lights. The tube in the middle
is actually a bundle of, well, the idea when I was making them was
wires. What might be considered a ladder-type deal was, in my mind
anyway, spacers to keep two wires separate from all the others. When
you turn the brightness up you can see the individual wires.
Unfortunately because the main lighting in the scene is blue the
multi-coloured wires are washed out into a muddy-blue colour. Such is
life.
To Jason in response to 'What is it?'
Well, I don't really know.. I was sort of thinking in terms of a long
shaft leading into the main reactor of a spaceship or some other
energy-generating source. How the wires are surviving their trip into
the fiery plasma is anyone's guess, but it seems clear that technology
has advanced somewhat from where we are now. :)
MikeH:
The glowing at the bottom of the shaft was created using a mixture of
lights, particles and fog. Four lightsources were placed around the
inner part of the shaft with an intensity of ~6000(!) and i/rr
falloff. Then a large sphere was particlized (is that the word?)
several times to give me just over 6000 faces with spherical
particles. ABFakely was applied twice, one effecting filter and the
other colour, giving a light blue centre fading to darker blue.
ABBoost was then applied and the colour slider was set to about 2.5 to
give a really intense white highlight in the middle of each particle.
Brightness was set to 255.
After that I created a CGI sphere, made it a fog object with a
density of around 500. I set the falloff to radial and the falloff
distance to almost the radius of the sphere. Then I hiked up the
overdrive to 3.5 to give a nice solid-looking centre to the sphere.
Then the fireball texture was applied and the colours were both set to
blue, with the same default intensity. I then scaled the texture axis
until the lighter (central) blue colour extended almost to the bounds
of the sphere. This resulted in a nice foggy object which looked
almost like the particles, but actually quite a bit nicer. Too bad
that, due to the fog "bug" the overlapping particles would cancel each
other out if I had made them foggy instead of transparent.
Unfortunately most of this will only work with IFW and the 1.3.4
update, but you could achieve similar results using fakely.itx for dos
and amiga versions of imagine.. and abboost instead of the overdrive
for IFW 1.0..........
Well, that was fairly long. Hope someone finds something useful in
there! Sorry for the bandwidth.
