	There is also a commercial package called "3D workshop", it's about
$200.00 (definitely under $300.00). It's a bit slow compared with 3D studio (
from review), and it dosen't have texture mapping.
	By the way, I thought 3D studio also did ray-tracing, if not, can you
tell me what technique they used ?

Does anyone know how the TV add "intel inside" was done? This is the

internal boards and ends up at the 486 processor. 

I say it's a model with a little bit of 3D thrown in (the funny light

Hello, 

Recently I came across a paper titled "Efficient editing of 
solid models exploiting structural and spatial locality"
(Computer Aided Geometric Design, 1984) authored by 
Robert Tilove, Aristides Requicha and Mark Hopkins.  I'm
interested in finding out more about their techniques and
latest results if any.  

Does anyone on these newsgroups know where and how I might
be able to locate any of the above three authors?  The paper
says that Dr. Tilove is at the GM Labs in Warren, MI but 
that was in 1984.  Could anyone confirm?

The above paper deals with dual CSG/B-rep geometric modellers, 
and outlines a method of (quickly) updating the B-rep when a 
CSG-node is to be edited or replaced.  If anyone here has other
references related to this topic, I'd like to hear from them 
as well and discuss this problem.

I'd appreciate responses via e-mail since I'm not a frequent
user of rn.  

Thanks in advance!

I have watched it after reading your message (on CNN) and i am almost sure that it has been constructed as follows. It is a model indeed and obviously a motion
control camera is used to do the fly-thru. The floor is computeranimated and
follows the camera movements. ILM has done a lot of this stuff.
We also have done a few commercials this way. There are ways to port camera/track (xyz) data to a animation program. I believe that i have seen the floor 'shuffeling' a bit while moving; but it can be our CNN dish! Watch the seams between floor and 'bookshelfs'! The rest is clever lighting, nice model and high-end computer animation.

Subject: Best way to scan in pictures? (Newbie question)
Organization: TECHbooks --- Public Access UNIX --- (503) 220-0636
Date: Sat, 9 Jan 1993 03:41:07 GMT

So, OK, I told my sister that it was possible to scan in photographs and
display them on her computer screen.  Now she wants to know how to do
it, and I don't really have any idea.  She has some slides and some 
photographs of her trip to New Zealand that she wants to scan.  All
these pictures are full-color.  

Here are my newbie questions which I hope somebody can answer so I can
up the pose of "big brother the computer expert".  :-)

(1) What kind of scanner works best for scanning in photographs?  

(1a) How much do they cost?  Is it possible to do a "good" job with one
of those scanners I see advertised below $500?  Below $1000? Or is any 
scanner under $10,000 (or $25,000, or whatever) pretty awful?  

(1b) Alternatively, do most large cities have print shops (or whatever)
that do this type of work?  If so, what's a reasonable price per
picture?  I've seen places that do OCR, but when I called, it turned 
out that it was cheaper to rekey (so I still have stacks of articles
that I'm supposed to type in ... someday ... :-) ).  The yellow pages 
seems to have only places that do OCR or "line art" under "scanning" 
and none of the print shops nearby seem to do image scanning.

(2) Is it even possible to scan slides?  I wouldn't think so ...

(3) Given a decent scanner, do you have to do a lot of touchup work to
get a decent photo on the computer screen?

(4) I don't know anything about the Kodak CD cameras.  Can someone 
outline the good and bad points of these?  I assume that it's possible
to read these into a Mac or PC somehow, but that might be a wrong
assumption ...

(5) GIF files always seem pretty large, but I understand that JPEG
format loses some details.  I've got all monochrome machines myself, but
she's got a pretty snazzy Dell (running DOS and Windows) at work.  What 
format works best for a SuperVGA card?  

(6) What's the best viewing program for a DOS box?  Windows? (I'd say
"best" was defined as good quality images fairly quickly, though some
would probably prefer image quality or speed.)

Sorry if these are frequently asked questions.  I checked the
comp.graphics FAQ and didn't come up with any answers from that.  The
alt.binaries.pictures FAQ had the names of some viewers, but not much
else information.  

Thanks!

I was concerned about the standardization of JPEG
between two programs I have, so I did some tests.

The original file was a 24-bit true-color file of
size 768 x 768 at 300 dpi, scanned into PhotoStyler.
I saved the file in two formats: 24-bit Targa and
24-bit BMP.

To ensure that both files had the same color
information, I checked the number of unique colors
using Paint Shop Pro. Both TGA and BMP files reported
having 167510 colors.

Then I compressed them using ColorView 2.0 for DOS
and WinJPEG 1.6. (The reason why I used a quality of
74 and 76 for Colorview was because it did not
offer 75 as an option; so I also used those settings
for WinJPEG.) Also, Cview only accepts BMP files.

Original   Software   Quality   Entropy   File
  File       Used     Setting   Optmztn   Size
------------------------------------------------
  TGA      WinJPEG      75        Yes     135909
  BMP      WinJPEG      75        Yes     136256

  BMP      Cview        74        N/A      81795
  BMP      Cview        76        N/A      84487

  TGA      WinJPEG      74        Yes     133183
  BMP      WinJPEG      74        Yes     133519

  TGA      WinJPEG      76        Yes     141489
  BMP      WinJPEG      76        Yes     141800

  TGA      WinJPEG      74        No      143693
  BMP      WinJPEG      74        No      143693


I am very confused by WinJPEG's method of saving JPG's.
WinJPEG takes two original files of the same content but
different format, yet outputs JPEG files of different sizes
(with entropy optimization on).

Cview's JPEG output is much smaller than those of WinJPEG
for a given Quality.

My questions are:

Which program adheres closer to the Quality settings
described in the JPEG FAQ?

Exactly what is entropy optimization and how does it affect
the quality of the compressed image? (Should it be used if
I want a "standard" Q75 JPEG file?)

And for those who have PhotoStyler 1.1a: how does the
quality range in the JPEG export module translate to the
quality range described in the FAQ? (PhotoStyler uses
a range from 0 to 100, with 0 being minimal compression,
100 maximum - just the opposite of convention). What
the heck is the difference between YUV422 and YUV411
SubSampling?

Sorry to ask so many questions, I'm just very confused.
Thanks for any info.

What I want to do is: Learn POSTSCRIPT programming,

SW-wise, I have Windows 3.1 and vi. No PS stuff.
I assume I will need:

 (1) A POSTSCRIPT interpreter/compiler.
 (2) Some PRIMATIVE Windows app, which need only 
     read output of (1) & send the PS stream to the NTR.
       (maybe 1 & 2 come togeather in some package).
 (3) A Windows driver for said app.

How might I obtain these? Preferably at low cost, it can
be kludgey, it's just for fun.

   Sorry... It's going to be very hard to find a ray tracer for an IBM
   compatible comuter for under $500.... If you do find one, it may not
