105.0. "The Last Starfighter again" by XENON::GAUDREAU () Mon Jul 16 1984 16:07
The last Starfighter - Some thoughts ...
*** SPOILER ***
I just saw this movie on the 15th at the Brandt theatre. All I can say is
WOW!! The computer graphics in the movie are fantastic. The article at the
end of this note will explain why too!!
One thing I thought peculiar, and haven't been able to check out as yet is
the character GRIG. Grig is the lizard like being that helps Alex out in the
Gun ship. Odd thing is, he reminds me a LOT of that character in BATTLE BEYOND
THE STARS called a "Sithule" (the lizard like creature with claws for hands who
runs the Zyme collector and has Kelvin helpers). They look a little like each
other but they sound EXACTLY the same, too me at least!!
About the video game which the Star League called the Excalibur Test. Rather
Earthlike for a name, eh? When Alex broke the high score, why didn't the
machine take his picture or something? Centauri had to ask, so the machine
didn't help things along. It could have also recorded the needed info for the
beta unit. When Alex was being chased by the "Hit creature", the machine erased
its disguise, why didn't it just blast'em?? Lastly, when will this game come
out? I want to play and play...

3-D Images for the Film Industry
Behind Digital Productions' Closely-Guarded Doors
By W. Mike Tyler
The largest producer of computer-generated 3-D images, in terms of
sheer volume, is located in an obscure section of Los Angeles.
One might not even notice Digital Productions' presence if it were
not for a huge water cooling tower, or the extra power lines
coming from a nearby utility pole.
John Whitney, Jr. and Gary Demos founded Digital Productions in
1982. Together, they developed a process known as Digital Science
Simulation(tm) for creating totally computer-generated images for
the film industry. This month, the firm will add motion pictures
to its list of TV commercial accomplishments when Lorimar
Productions releases THE LAST STARFIGHTER, a full-length feature
film containing 21 minutes of computer-generated images.
Behind Digital Production's closely-guarded doors is the most
sophisticated hardware and software ever assembled for the sole
purpose of creating computer-generated imagery and simulation.
The facility is capable of producing 12 minutes of film per month,
where the average frame complexity is 250,000 polygons. At 24
frames/second, that is 17,280 individual images (4.3 trillion
polygons).
To accommodate this intensive computational load, Digital
Productions has acquired a Cray X-MP computer (hence the need for
the cooling tower which extracts heat from liquid freon
circulating through the Cray's PC cards).
In addition to the Cray X-MP, Digital Productions has a full array
of data entry, encoding, and movie previewing workstations.
Ramtek RM9460 imaging/graphics display systems give technical
directors the ability to view fully rendered images before they
are committed to film. The amount of data that can be displayed
is 1280 x 1024 pixels x 24 bits per pixel, or approximately 4
mega-bytes per frame. Interfacing to the Cray X-MP via a DEC VAX
11/782, these previewing stations provide immediate feedback and
allow the technical directors to experiment with a variety of
different display attributes. The hardware also includes a 2560 x
2048-pixel by 10-bit/color film recorder and a high-speed custom
interface to the Cray IOP. Both were designed and built be
Ramtek.
From a systems perspective, Digital Productions' designers are
interacting with a graphic database--representing 3-D shaded solid
objects, something common to many CAD system designers. However,
the scope and scale of their system sharply departs from your
everyday CAD operation. This has to do with the special
requirements involved in the production on images for film. Most
significant is the need for raw computational speed.
Quality film production work for a single 35mm frame requires a
film recorder resolution of 3000 x 4000 pixels and 10 bits for
each color. At 10 floating-point calculations per color, per
pixel, it would take 8.64 billion calculations to produce one
second of film (3000 x 4000 pixels x 3 colors 24 frames/sec. x 10
calculations/color pixel).
In creating realistic computer-simulation scenes, lighting and
rendering algorithms require one to 10,000 calculations per color.
Thus, anywhere from 864 million to 8.64 trillion calculations are
needed to produce one second of animation. The Cray, at 200
million floating-point instructions per second, takes anywhere
from three seconds to 10 hours to generate one second of film.
Since adjacent frames contain common image features, programming
shortcuts exist for reducing the overall number of calculations.
Large-format 70mm movie film resolution (4600 x 6000 pixels/frame
x 30 bits/pixel, or approximately 100 Mbytes of data) ups the
computational requirements even further.
How economical is all this? In the case of THE LAST STARFIGHTER
production costs were significantly lower than filming scale
models of the Armada ships and performing post-processing to make
them look real. When comparing industry firsts, THE LAST
STARFIGHTER includes over twice the amount of simulation that
appeared in STAR WARS, and was produced in approximately one third
the time, at about one quarter the cost.
CONCLUSION
There are fundamental parallels between Digital Productions'
supercomputer environment for film-making and high-performance
systems for mechanical CAD design or engineering simulation. All
have a common purpose: design productivity. Each has its own
intensive computation burden.
But not everyone can afford access to a Cray-class computer.
However, these application needs have spawned a new generation of
graphics peripherals with special-purpose computation accelerators
to tackle the dynamic display of complex 3-D solid objects.
Ramtek's new 2020 products fall into this category. The major
improvement brought by this class of device is the 3-D design
takes that formerly took anywhere from tens of minutes to hours
can now be done in seconds.

I finally saw this film last weekend - entertaining, heavily loaded
with deja vu from Star Wars and other pop SF films, and with excellent
effects.
The effects, though, reminded me very much of TRON and Automan -
as a casual observer, I didn't see much pioneering going on here.
I liked the film - but I'm really turned off that what this really is
is not so much a movie, but instead a two-hour advertisment for a new
video game from Atari.
I feel sorry for them - the video game market is dead - and it strikes
me that this movie is a last-ditch effort to get those quarters falling
again.

| Two observations:
(1) It's funny, but the special effects did *not* remind me of TRON at all.
TRON's computer-generated images were more of the "grid pattern" variety,
while THE LAST STARFIGHTER's images were solids.
(2) On the other hand, I understand exactly what you mean about it looking
like an ad for video games. My biggest disappointment in coming out of the
film (which I *did* like, despite the flaws), was that I felt like I had
watched a video game rather than a movie.

| "Excalibur test" didn't refer to the Starfighter game, but rather to the
similarity of this ploy to the trick which had been played, a long time
ago, on a guy named Arthur ... this was slightly better detailed in the
book.

| and Arthur said (more or less) :
"King? What do you mean, 'Your the new king'? Is that, like, ultimate power
over man and beast, armies, and such? But I don't want it..."
and Merlin said unto Arthur (Just like Centauri) "My boy, think of the
possibilities, the opportunities, the WEALTH, the power. Think of your country,
do YOU want to let them down, why, you could help them, make them better than
they are. Everybody wants to be king, it's an honor boy, you just HAVE to
accept it!!"
and Arthur did reply "Hogwash, don't pull that Freudian ego stuff on me!!!"

| Sorry folks but there is only one computer generated scene that
I could find major fault with. The entire family enjoyed the flick
and I didn't even think of it as an ad until now (in fact, I still
don't). Somehow it seems that I usually end up liking stuff that
most other people don't (I couldn't stand Star Trek until after
it had gone into syndication yet I loved Battlestar Galactica.)

105.6 | RE 105.5 | DICKNS::KLAES | The Universe is safe. | Tue Aug 18 1987 09:42 | 5 |
| So what was the "one computer generated scene" that you found
"major fault" with?
Larry

105.7 | maybe this is the one... | KALKIN::BUTENHOF | Approachable Systems | Fri Aug 21 1987 21:08 | 16 |
| I dunno about .5, but the scene *I* found major fault with was
when Centauri and Alex return to Rylos after the attack. There
is no sign of rubble, and the exposed ends of the fortress are
geometrically smooth. The center might feasibly have been cut
out and vaporized by energy weapons... but it was supposed to
have been blown to smithereens by "meteors".
With all that shading and anti-aliasing, you'd think a couple
of fractals wouldn't have been too much to ask...
Nevertheless, I really enjoyed the movie. Robert Preston
and the Cray were fantastic, and the story was interesting.
In fact, I just watched my copy of it last night, purely
by coincidence...

105.8 | Smack dab in the middle | EDUHCI::BOELKE | | Tue Aug 25 1987 17:24 | 4 |
| The 'objection' in .7 can, I think, be explained - the fortress
wasn't disarmed until they had destroyed all of the 'meteors' except
one. That one hit dead center - the launch bay.
|
105.9 | I don't buy it... | KALKIN::BUTENHOF | Approachable Systems | Tue Aug 25 1987 20:11 | 3 |
| One amazingly *neat* little rock, wouldn't you say?
/dave
|
105.10 | Felix Unger of Space Wars | EDUHCI::BOELKE | | Wed Aug 26 1987 12:32 | 3 |
| Maybe - but I would think that the complex would have been HUGE,
and a dead center hit would not neccessarily destroy the 'wings'.
|
105.11 | arrgh | KALKIN::BUTENHOF | Approachable Systems | Wed Sep 02 1987 20:52 | 6 |
| I never said it should have destroyed the wings. I said
it should have left jagged edges and rubble, not a clean
geometrically precise cut perfectly perpendicular to the
plane of the outpost. OK?
/dave
