RE: Fulldome names...
- Hum, how about Digital Dome Graphics (DDG)?

on the dome, regardless of format. My main "detraction" was from that
angle -- from the hardware (cheap LCD projectors, VHS tape) to the "hit 'em
with a blast of snow, then the picture rolls in..." presentations -- you
know what I mean. Then there's what you actually show with the hardware,
but I digress.
Now, the technology has advanced enough to make "something better"
achievable, possible. Still, nothing is simple, and there are a gazillion
tradeoffs, not to mention maintenance, alignment, reliability issues all
around. But at the Western Alliance conference in Eugene, for example, I
saw a video all-sky look better than a photographic allsky when A/B'ed,
panoramas that had color saturation and scalability. Dang, now we're
talkin'! 'Course it was a half-million dollar system, but what of that.
Steve Savage is actually more my "enabler", as it were. This year for IPS,
in order to show *anything* in the theater, it would need to be in fulldome
video. We've been getting the questions for quite some time now, "Is Loch
Ness going to be providing content for these fulldome systems?" So we're
finding out <g>.

produced a "traditional" 2-D planetarium show in fulldome. With Sky Quest,
and the clips from the other shows we're doing in our demo, we'll now have
a chance to see what Loch Ness shows look like in this new
medium. However, we are taking advantage of the opportunity to transcend
the limited 2D medium, as you'll see. The MarsQuest pans now have skies
above 'em, Venus has clouds and lightning over its pan, we can create a
whole dome montage without worrying about lenses on a dozen projectors, we
can zoom things wherever without worrying about inverse square law. For
now, though, we're concentrating on doing things in "enhanced 2D" -- we are
not starting over from scratch with 3D modeling and rendering. We're doing
the kind of show you would expect to see at an extremely well-festooned
planetarium. Well, at least what I would expect to see <g>.
And we'll have a chance to see how our traditional planetarium-style
storytelling holds up when played back to back with Oasis In Space,
Infinity Express, Passport to the Universe. And I'm sure people will be
most interested in dollars all around -- how much LNP product will
eventually cost in dome master form, how much did what cost to produce, how
do those dollars compare to the 3D wowzers, and on anon. As I said, I'm

the future is probably not in slide-based shows, so there you go. Whether
this means I'm keeping up with the market, or simply being buffeted by the
winds of change, I can't say. A lot of places are still slide-based, and
doing well -- and we'll keep serving them. As to how long... well, that's
why we have IPS meetings, to gauge these things!
Ryan chimed in:

rendering in the background right now. As long as a video system can pump
out circles at 30 fps, we should be okay (and this should include
MediaGlobe, in theory).

theory they should. Phil Groce has had several test discs of ours since
MAPS, and despite following what I think is every step in the manual,
they're not playing -- yet. I too am sure that this is just a snag -- if I
had a MediaGlobe here, I'm sure I could figure it out. We hope to show our
theater demo on the MediaGlobe at IPS, so one could compare/contrast... but
we're still in the waiting mode (Hello Phil!). I do think the MediaGlobe
has a positive future ahead of it.
