Well, SeaQuest DSV is actually more visible because it is a network show.
But I bet fewer people watch SeaQuest than watch Babylon 5.
We all know that these days a 1st run syndicated show can actually get
better ratings than a network show, at least in their own markets. Not
sure about cumulative ratings since there must be some gaps with 1st run
distribution where the show is not aired.
Other shows that use Lightwave:
Robocop (don't really see it much, or it doesn't call attention to itself)
MANTIS (not the best artists on this show in my opinion)
And now Earth 2. But since the ship crashed, I bet they don't need much
in the way of CGI modeling.
These days its almost a given that if it's a sci-fi show, you might as
well go with the Toaster/lightwave.
Babylon 5 paved the way with its pilot movie.
Even Paramount has jumped on the bandwagon it seems. Rumors indicate
that Voyager will break from the TNG/DS9 tradition and go all CGI, most
likely the Toaster. SGI workstations are still too pricey for series
television, even for Spielberg and Paramount. And I'm not sure SGI
workstations are really going to provide that much more.
Toaster/Lightwave can generate NTSC resolution images at a fairly
productive rate. Once you step up to film resolutions, SGIs become that
much more important. You are talking a geometric increase in rendering
times. If you have enough time on your hands, you could render a huge
chunk of NTSC animation on a pretty modest Amiga setup. Babylon 5s
initial render farm was nothing but 2 Amiga 2000s networked together.
------------------------------------------------------------------------
Now, with that aside, for those of you who have or are planning on
getting the standalone Lightwave for their Amiga. I've looked into it
and at face value, $500 for a commercial grade raytrace animation system
sounds like a great bargain. But if you ever plan on sending output to
videotape in a clear resolution, it's gonna be costly. SO costly in fact
that it almost makes sense to go ahead and get the full Toaster board setup.
Let me be more specific. The AGA Amigas have what I consider to be very
wonderful graphics which are perfectly suitable for sending directly to
video via a genlock. HAM8, when done RIGHT, can look just as good as
24-bits. For most applications, the limitations of HAM8 do not rear
their head. Certainly for the limited palette of Lightwave's most common
subjectmatter, space battles, this would probably not be a problem.
You'd save the frames as .IFF 24s and do a GOOD conversion to HAM8 to
optimize palette usage for each frame. But the problem now is HOW do you
send this to video? There is no way to drive it at 30fps. This means
using a single frame-capable VCR which is no cheaper than $1000 and
probably more, or you could forsake HAM8 and use DCTV so you can play
animations at full speed. I have yet to see DCTV output but supposedly it
is pretty good. HOWEVER, since it outputs composite only (right?) the
signal will be fuzzy because of this. Using an S-VHS or what not will not
make any difference.
So if you can find a cheap enough deck that can do single framing, you
are all set. That and a cheap external GENLOCK and you can even use an
A1200 w/HAM8 and probably get some amazing results. If the Genlock
outputs split video then you can output to SVHS which has greater
horizontal resolution than standard VHS. They also have these new Hi-8
VCRs believe it or not. But I don't know what these have for single
frame capabilities. But they have great sound characteristics and at
least 400 lines horizontal resolution capacity. These go for like
$500-$600 I believe.
I've seen some U-matic 3/4 decks floating around used, which I have to
assume have fairly good resolution statistics. But kinda poor sound. I
don't know what they have for video inputs nor do I know exactly how they
might handle single framing. But these can be quite affordable used.
The only other options are the Personal Animation Recorder and Vlab and
stuff, things which require a Zorro slot (thus invalidating usage of a
cheap A1200 or other non-Zorro Amy) or is way too expensive to consider
(Abekas tape output).
