Ah, OK. Not heard of that one...

Oh, don't get me wrong. Imagine 3D was quite a nice program. Just don't
expect reflection or refraction to work properly! Everything else works
though...

Yeah, or maybe I just need to sit down and write something in Java... ;-)
[I'd use Haskell, but I can't get the bindings for libSDL to work. At
least, not on Windoze. Works fine on Linux...]

48 kHz was already standard in recording studios on DAT tapes, and I assume
it was also used for movie sound. So that is why DVD used 48 kHz, but where
that frequency came from in the first place I don't know. 48 kHz is quite a
nice round number, so I guess they just made it up.

OK, I rephrase: Real3D didn't have this feature. :-P
(BTW... Do you know of any real modellers that do? I realise
theoretically somebody could make such a thing, but do you know of any
real programs that do this?)

It's easier to see the difference on brighter monitors in darker rooms.

Amiga Format gave away a coverdisk containing almost all of level 1 of
Flashback. After spending a week completing it, it was perfectly clear
that I had to own this game.
My dad eventually purchased the ECS version. I've never played the AGA
version, but it seems some of the cut sequences were much longer and
more detailed.
Unfortunately, attempting to play the ECS version on an AGA machine
results in the audio and video getting out of sync. (Apparently it's
timed according to how fast the graphics can be drawn, so on a more
powerful machine, the graphics draws faster and gets ahead of the
music.) Bit of a pity. Oh, and it doesn't run on my Amiga with its
updated ROM either...
That was a damned fine game. I adored the graphics of the opening level,
although many of the other levels were much less graphically
interesting. The final level was just awesome.
I don't suppose you even have the game any more, but where did you get
stuck?

I think you're right.

Seems plausible at least.

The property you're after is "paremetric modelling", where instead of only
being able to assign numerical dimensions, you can apply rules and formulae
based on any other dimensions. Commonly you can do things like "make sure
this face remains parallel to this one", or "make this radius half of this
dimension" etc. Then of course when you change one thing, everything else
updates.

I see...
The examples given seem to indicate that this is only a feature of
extremely high-end CAD products though.

There was a really good free CAD package called ProDesktop, but they stopped
releasing it a few years back which was a real shame. Maybe you can somehow
find a copy of it.
A google for "free parametric cad" brings up some candidates, the first one
called "Varkon" looks ok.
