#Underwater in Imagine
29 messages in this thread
Howdy Paul, have you ever experimented with UNDERWATER Scenes in Imagine?
Were you able to get realistic results???? I saw Erik Floms Demo Reel and
it had just such a scene and it looked GREAT and so I of course had to try
the idea. My first attempt was a FLOP. Any light you can shed will be
apreciated. Thanx
Peter,
No, but I have read that section in Steve's book and it sounded neat
and worth trying.

<Steve's Book> Understanding Imagine 2.0???? Egads, Time to dig that PUPPY
OUT again. Tho Erik Did mention he used some Non linear Greenish FOG so
I'm going to try that myself too.
Hi guys, why don't you just buy some of my REAL underwater scene frames. Great
for back grounds, on disk from video, clean too and it's the real world, and
you don't have to dope out the program.

Of course the problem with using REAL underwater scenes for backgrounds is
that the illusion of reality falls apart the first time you move the
camera.
Jeff, i'm missing your point about loosing reality. would you explain. george
George,
Imagine you're doing an animation that takes place in about 40 feet of
water. You want to use an image of a reef as a backdrop. The animation
starts with a view of the reef and a computer generated fish swims into
view. The camera them pans to the left to show a minisub cruising over the
bottom. Since you're using a background that's fixed to the camera when
the camera moves the reef stays in the same spot in the view and it
appears that the sub slides sideways into the view rather than the camera
panning to the side.
The problem can be avoided by using a sequence of backgrounds but it's
VERY hard to syncronize the movement of the computers camera with the
sequence of background images.
Most of the 3D animators that want to do underwater stuff want to do deep
water scenes. Since there's very little light or plant life below 100 feet
it's much easier just to use a dark fog and a smooth landscape for the
bottom of the ocean.
I tend to use backgrounds only for very complex scenes with a lot of
detail. (A flying saucer takes off from the center of a city and flys past
the camera) With a scene like that you don't HAVE to move the camera to
get an interesting shot.
Jeff, I shoot in all depths, from shallow with ambient light to 130 ft and
more. There I use lights. Heavy duty puppies giving me 3400K. As for still
reef, well that depand on a shot. Sure, many shots the camera is still, the
back ground is in one place and the subject is moving. But often when i swim
through along the reef, the whole image passes, or pans. It all depands on a
shot. Depands how it's used. An animation is animation. Motion video is just
that. But often one frame as backdrop is neat for c.g. or whatever. george
Email me Details. Are they avail on CDROM or Syquest Carts???
No Peter, I simply freeze frame with tbc from live video and save on disk
through toaster in rgb. I shoot my own video underwater. Have good scenic,
sharks, fish, divers, wrecks, invertabrates, octopus, eels, dolphins, you name
it. Benn shooting for about 12 years video and 3 years film. are you
interested? george
Please email me details/pricing/method of delivery etc. I'm interested in
Stills mostly in IFF24 or JPEG form.
George,
Your underwater images sound interesting. Have you uploaded any
samples. You could composite four quarter screen images. That way we could
take a look but the images would not be useful until you bought the real
full screen version.
I use real 24bit images in my 3D animations all the time. I also add
hand animated effects to 3D animations. Whatever works to produce the
images I have in my imagination. However there is a real kick to creating
a virtual reality that works right in a variety of situations. I view the
challange of translating a series of images that reside only in my
imagination into a working virtual reality within my Amiga as a great
puzzle – much more interesting, fun, and engaging then any game I could
play on Ami!
Sometimes you need water to react with animated objects. For example:
A DS9 runabout enters the atmosphere of a planet. It descends to the
surface of a great sea. "Shields up" The spherical shields are invisible
except where it contacts the water as the runabout descends. The water is
displaced as the runabout submerges, revealing the shields shape.
Underwater the runabout moves off surrounded by shields to an underwater
city.
Wow, that one sounds interesting enough to try. . .;)

It sure Does. When ya do this Underwater Runabout Anim I'd love to see
it.
First I've got to build the runabout ;)! I've got to get two Pagestream
projects (next year's school calendar and a literary magazine) out the
door, then I'll get going on some fun stuff!

Good Luck Modelling the Runabout. I've modeled "A" Runabout but it isn't
very similar to the one from DS9. If you like I'll send it up to area 10.
It uses some Essence Textures to make it look more interesting.
Peter,
I bought a magazine that has a pretty detailed photo of the runabout
that shows alot of panel detail. I think I have enough to produce a pretty
good likeness. I think I can save some time by using modified versions of
Carmin's Enterprise Warp engines, but I still have to wait until I have
the time to get into it. Of course if got off CIS and Genie once in a
while I have more time ;)!

-Paul-
Tell me about it. CI$ and Genie Eat up ALOT of my Time as does the
TradeNPost BBS. I just finished a SILLY Alien Model That I will also
Upload.
Uh-oh, what's the "TradeNPost" ;)?
…AutoPilot Engaged…
-Paul-
TradeNPost is a 4 line Local BBS that carries ALOT of Fidonet Echo msg
bases. It also is Getting a LARGE collection of 3D models online. The
Sysop is a Toaterite and there's quite a few others as well as Imagine
Dabblers like myself.
Paul, I'm basically a computer idiot. I shoot video and edit. Loading up and
sending images on cis, you must be kidding, i would not know where to begin. I
freeze frame from video and save in rgb through the toaster. They look great. I
even had some frame stores transfered to slides, shocked the heck out of me how
good they came out. Right now I'm saving a few for a video slip case cover
print. let me know if thereis an interest. I ussualy edit video and sell, and
have sold raw footage on a buy out basis. trying to see if there is a market
for still images for back drops. george
Say, Paul —
Where's the rap on underwater scenes in Steve Worley's book? I'm interested,
but don't see it!
Thanks,
John D.

<Fog is very versatile…If you make a dark blue-green color fog with a
moderately short fog length, you can make some terrific underwater
scenes.>
Not a great deal of direction…
I hadda reread thru the book to find the bits on underwater. Ther's no
listing about it in the Index.
The January 1993 issue of Amiga User International has 2 pages of FOG tips
for Imagine 2.0. Page 54. *8>

Amiga User International eh? I'll have to look for that Rag.
John,
Oh sorry to mislead you. There was no big section on UW scenes. Steve just
mentioned some fog settings that would give an underwater effect.

Paul —
No, ya didn't mislead me! I finally found the underwater section in the Fog
chapter — good idea — thanks!

Hey man. You gots to quit dropping my name. This is getting embarrasing!
