The problem is commom and frustrating, but there is an answer! Got into 
the action editor and add a global size with the default 0,0. Do this 
evertime you use raytrace. I spend hrs trying to figure this out until I 
called Impulse. It should have been a default setting.

Sorry, I was in a hurry when I posted this. Our comp lab here is only open to
us ugrads for another week (arrrgh time to buy a modem!!).

I do a lot of rendering (both stills and anims) with Imagine, (i'm very
interested in the new developments in this and other packages however), and
for starters would like to be able to output these (Ham i'laced) to video (VHS).
I assume I can do this straight through the composite out?? Eventually I
would like to start outputting 24bit stills and anims to tape but the extra
hardware is prohibitively expensive down here!! at present. The paint package
sounds excellent - better than MacroPaint (IV24) at any rate, and I would be
a keen user of this on my collection of pix, etc...

Apart from these which are my main aims, just generally playing and
experimenting :)

A PIP feature would be nice so I can watch TV as I model in Imagine!!!!!!
Just sit the window over one of my side views...

Thanks for your replies so far (sorry I don't have priviledges to email any
replies...)
Matt.

You can find pictures of the new Real3D 2.0 interface at nic.funet.fi in
pub/amiga/applications/commercial/pictures/. The file is Real3D-2.0-Pics.lha
or something like that. I took the time to download the archive (about 140K)
and was simply amazed (along with a MacIIci-owning friend of mine).
Believe me when I say that anyone with a stake in 3D ought to download the
pix. They are simply amazing. Download them now, and then dream for a while.

As far as specs are concerned, well I only own half the story, but what I've
heard so far has convinced me to take the upgrade path from 1.4.2.

such as: Spline paths for objects, motions; a Forth interpreter awaiting your 
commands and new word definitions for easy mathematical object creation,
motion or layout; lens flare effects; totally customizable interface (the
pix will prove this assertion more than amply enough); each user-defined
window has its own rendering mode (yes Virginia, that's right. You can,
while in the modeler, have 6 windows or more, each with its own point of
view, camera tilt, etc..., and its own rendering mode (scanline, wireframe,
ray trace), and each rendering while you design; cut and paste operations
from one rendering window to the next; laws of physics are respected to
a certain extent, i.e. make a cube and a sphere. Place sphere on top of
cube and tilt cube. Sphere rolls off... :); and more...

Trust me. You want to download those pics.

Harv, what do you think of the new scanner from Migraph, the PS400 Wand.

It scans 8.5' wide, up to 14' long, 100-400 dpi in 10 dpi increments
with Touch-Up software.  It does 200, 300, or 400 dpi with Migraph OCR.
Uses 8x8 dither for halftones, a line art mode.  It's MUCH easier to
keep it straight because of the widely spaces rollers.  It goes for $500
with Touch-Up.  There's an optional sheet feeder for $200.  I saw it at
WOC in Pasadena and my order is in.

Oh yes, you need a 14MHZ Amiga with at least 2MB of RAM and a hard
drive.  You'll 4.5 MB for the OCR.

I can't hardly wait!

The Sharp JX100 model is a couple years old. It originally sold for
nearly $1000. I don't know if it's been discontinued or what. It is
neither a hand-held scanner nor a flat bed. It's kind of a mutant of
the two. Imagine a regular loaf of white bread sliced in half 
horizontally the long way. That's about the size of the JX100.
Its "bed" (actually its scanning window) is about 4x6.5 inches. 
It takes one pass of the scan head to do monochrome or grayscale.
It takes 3 passes to do full 18 bit color. The scan head contains
color filters which the scanner changes itself on each pass. The unit
is sealed up and you don't have to muck around inside it. In fact
it's 100% software controlled and doesn't even have any external
controls on it itself. ASDG's ScanLab/100 support software is pretty
good. Even better is their JX-100 "loader" which runs inside of
Art Dept. Professional. 

At $1000 the JX100 was wildly overpriced. At around $300 is a fair
bargain. Scanning its entire bed (4 x 6.5") at 200 DPI in 18 bit color
takes about ten minutes. Compared to full page flatbed 24 bit
scanners (like the Epson ES300C) this is very slow. Compared to any
other small half page color scanners it's fast because there
aren't any others :)

The JX100 connects to the serial port. You can't use any 3rd party
serial boards for it. ASDG's software (to use Perry's terminology
in an earlier posting) bangs the serial port pretty hard to get as
much data flow speed out of the JX100 as possible. 

The little scanner delivers excellent results. Very clean, very 
uh.. well Sharp :)

The archive contains a 68000 and a 68020 version of the tracer. It works on
normal Amigas, but slooooow ...
I recompiled it for my '030 and gained about 20% of speed :-)
Speed is ok, and the best thing is that it compiles at our university machines

 Speed is about the same as DKB trace, depending on the complexity of the

I only have a Stereo VCR (Realistic Model 33) at present.  Hoping to pick up
another Stereo VCR (Sanyo model).  Pausing makes line-bar noise... Ick. I don't
know if the Laserdisk does or not.  I have a Stereo TV/Monitor (Realistic,
planning to buy a new Stereo TV soon) and when I pause, I don't see a picture,
except a blue screen (with PAUSE).

That's another problem I have.  Trying to get the "correct" colour match with

That sounds pretty cool.  Now I have to figure a way to get both my TV and the
computer + the Laserdisk in close proximity so I can digitize.  (They are on
opposite sides of room, and can't find RCA cables long enough to do the job
just right...  Ugh)

I'll give it a try...

Does it matter what format the LD is?  Am also curious about that, for I have
some disks in the CAV format (eg, Dirty Pair: Affair on Nolandia,Terminator
2:Judgement Day Special Edition) and CLV format (eg, Vampire Princess Miyu,
Star Trek II:TWOK).  If it can work with either, great.

(Do I have to use Pause or what?  Don't have a frame-grabber)

Tschuss!

	I assume that it would not be too difficult as people were
showing demos of OpalPaint on normal TV sets, albeit through
the RGB inputs of the TV sets.  Perhaps someone else who has
this board can comment.  Normal Amigas though just need this
Commodore adaptor box (around $30) to output to a normal VCR.

	What are you going to be doing with the paint program?
It seems to me that a lot of the utility of the program
would be lost if you didn't have a pressure sensitive pad
to draw on -- this is another $500 to $800.

  Well, instead of all that compiling and recompiling of the OS, not saying
that my idea wouldn't require some recompiling, why not just let Commodore use
whatever CISC processor they want for the main CPU, and use RISC for the rest
of the machine?  You know, like jerk out the blitter and paula, and the like,
and replace them with one or two "68000s of the RISC family" if there is such
a beastie.  And include a nicer RISC chip for the math co., recompiling only
the specific libraries associated with each replaced function.  i.e. graphics.
library, audio.device, math*.library, ect...  I'm not an engineer, and don't
claim to be, so no flames as to how impossible my idea is, but since we're all
in the business of redesigning the Amiga here, i thought i'd post my two cents
worth.  One thing i might also throw in, is that i was looking through a Byte
magazine a couple months ago, and they had an i860 based number "smasher" card
that put out 80 MFLOPS, which IMHO would certainly be appreciated by this avid
ray-tracing fanatic, as well as others i'm sure.  In this day and age, i think
the Amiga needs some serious redesigning, in that it should be endowed with
real coPROCESSORs, and not just custom chips.
 
  Another thing i was sorta "mulling over" the other day was why not reduce
the AmigaOS down to i guess what would essentially be called a microkernel,
and have a kind of generic CPU slot not unlike the one that is already present
in the 2000 & 3000, but with much more bandwidth, so that one could later buy
a specialized module that might contain any kind of cpu produced, plug that in
and boot off of the included disk for that module, and have any kind of CPU
you wanted, from say a 486 to the Alpha to a SuperSparc, ect..  The included
disk would simply include the cpu emulator software which would be initially
loaded and configured by say a 68000 or something...  That way, Commodore
could ship the machine with the cheapest cpu they wanted, and the power-hungry
users could upgrade to whatever CPU best fit their needs...  Sure it purely
speculative, but admit it, it held your attention long enough to get this far.

TI's SuperSPARC can get up to 3 instructions per cycle and DEC's Alpha up
to 2.  

IMO the SuperSPARC looks like a great chip.  It has _lots_ of cache
and lots of stuff for MP.  One of the things I like best about SPARC though
is you can get it from multipule vendors.

I read in the Five-Minute NEWS that the Amiga 4000 will work with all 
Amiga software (short of those not compatible with 2.0 or later)...
So there you go. 

It is good that CBM finally did something good for a change...
But I wonder what the 4000 is missing... There is bound to be 
something that is wrong with it since it wouldn't be consistent for 
CBM to create a machine that didn't have any system faults. 

I hear that the ATARI Falcon's will be coming with a Motorola DSP
and VGA graphics, with a hardware port for MPEG image compression...
This could be hype... But if it is true.. call me an Atari/Amiga 
owner...
