There are quite a few more machines with hard disks than with 8 megs of memory. Perhaps in the future the 8MB demos could be done in such a way as to run in a small amount of memory, and be read from the hard disk on the fly. This would make large anims available to a much larger audience. I don't know what the machanics are exactly, but I do know that current controllers and disks ahould be able to keep up if the disk isn't too fragmented. Any comments? -- *** Sean Casey sean@ms.uky.edu, sean@ukma.bitnet, ukma!sean *** Copyright 1989 by Sean Casey. Only non-profit redistribution permitted. *** ``Nuns. No sense of humor.'' - Kurgan

I haven't tried it yet, because I don't have an anim that big.

Tom Smythe, of Real-Time-Systems, the *BEST* seattle amiga dealer (Sorry, OMNI international, but you're overpriced slow and stupid) for the recent computer fair, put together an *ELEVEN* megabyte animation featuring a side-view of a dragon which would turn its head and the camera pan angle would move 180 degrees.

$Yeah.
$What's the point?

$(Sorry, OMNI international, but you're overpriced slow and stupid)
Thats funny I did a request for dealer evaluation about four or five
months ago and I got a lot of compliments about OMNI International and
absoluly no complaints. I guess the old saying still holds (if you got
nothing good to say refrain!
$for the recent computer fair, put together an *ELEVEN* megabyte animation

The animation of which you speak was created by Glen Grahm the same person
who created the shuttle disk for Sculpt 4D. I can at least agree with this
opinion!
$But...The point is He was running 11 megabytes internal chip-addressable ram.
$No hard-drive access.
$
Boy 11 megs of INTERNAL CHIP-ADDRESSABLE RAM. I guess he also had special
versions of the custom chips designed by Jay Miner to address this much chip
Huh? What he was running was a CSA 020 board with piggyback 030. The
CSA Dragstrip with dual 2058's populated with 4 megs each. And one more 2058
in another slot, So this gives us...
8 megs CSA Dragstrip
2 megs A2058
1 Megs Chip
11 megs total.
$He got around this limitation by using a 32-bit memory addressing

$
$For large animations, I think THIS should be the trend and not the obvious
$tending toward hard-drive dependancy.
$
So if I unedrstand you right then we should forego the writing of software
that will enable us to run animations larger than the amount of available ram.
Sounds pretty short sighted to me!
I guess I shouldn't be so critical but the slam against a Good dealer without
supportive evidence really burns me. Omni works damn hard to sell the Amiga
and also to help out the amiga community in general. Nuff Said!

Lamont | | What's the point?!?!?!?!?!??!?!?! I'll tell you what the point is. The point is that this guy was running some very bizarre and EXPENSIVE hardware. Let's look at this reasonablly. A large hard drive, like say a 100 meg SCSI Quantum and a GVP hard card cost about $1200, while RAM is going for much more. Say a Microbotics 8UP with 8 megs RAM is $1795. This is not your mythical 11 meg 32-bit Super-non-standard-won't-autoconfig-worth-sh*t RAM board but you get the picture. This 11 meg animation required around $3300 worth of RAM chips, plus a 68020 accelerator plus a hard drive to store the animation on to begin with! So why not exploit the fact that this ridiculously large animation is sitting on your hard drive somewhere and play directly from the bloody HD!? There are a whole lot more people with 11 megs free on their hard drive than there are people who have "11 megabytes internal chip-addressable ram." In fact there is no one with that much "Chip-addressable" RAM unless people have been busy etching their own Uber-Agnus-on-Steroids and building their own Amiga 3*10^9 motherboards. This guy was either pulling your chain or having a VERY good time with some nifty chemicals. #8^) Down to the point: It would be silly to require ultra expensive, non-standard hardware to view large animations when thanks to some ingenious programming it can be done much more inexpensively on standard hardware. Isn't the whole point of distributing animations allowing the maximum number of people the enjoyment of viewing them?

I was browsing at a bookstore recently and I believe that Antic's Amiga Plus had just such an animator. I believe it required a hard drive but it was supposed to load and play at the same time.
