   Hi, there is a 3D American map demograph with the
   48 states' population and income data on Indigo
   machine. It has four display options: draw line,
   draw top, draw solid and draw lighted. We have
   the original code and we are trying to modify it
   to be a Texas county(254) map. After figuring out  
   the data structure, we created a binary file, 
   "counties.bin", with normal system as follows for
   side faces:  

       taking any consecutive points (x1,y1,1) and 
       (x2,y2,1) on the top, it could create a side 
       face by adding (x1,y1,0) and (x2,y2,0). So 
       the normal of the face could be determined by :

                        |   i     j     k |
   ----->   ->   ->     |                 |
   Normal = L2 X L1 =   | x1-x2  y1-y2  0 |                                     
                        |                 |
                        |   0     0    -1 |

            = - (y1-y2)i + (x1-x2)j + 0k
                          
            = [-(y1-y2), (x1-x2), 0] 
   
   then the normalized normal is

       -->     -(y1-y2)    x1-x2
        n  = ( --------,  --------, 0 )
                 NORM      NORM

                                      2         2
   where  NORM= square root[(-(y1-y2)) + (x1-x2) + 0]


                          Z
                          ^
                          |

               (x1,y1,0)/      (x2,y2,0) 
                       /
                      /
                     X             
    

   The problem is that we couldn't get correct illumination
when displaying in draw-solid and draw-lighted, they are just
reversed (lighted sides to be dark and dark becoming lighted)!
   
    The normal system of the original code seems using

       -->      x1-x2     -(y1-y2)
        n  = ( --------,  --------, 0 )
                 NORM       NORM

 but it can't make any sense why they calculated in that way!
and we have tried all possibilities of the normal system 
(including their way!), unfortunately, none of them works!
We began to doubt there might be something wrong in the normal
system of the original programs and they were fixed in somewhere
else?

    Could anyone help us to figure out what wrong it is? Or 
any suggestion? Thank you in advance.

I am having problems getting my Panasonic KX-P4410 Laser Printer to
print properly.  If you have this printer, I would be greatly obliged to
hear from you via E-mail.

I currently have HPLaser.Driver in my devs/printers directory, and am
using it in my preferences.  Now I have not been able to get anything to
print from the CLI or a disk manager program.  So I tried printing a
file from my WordPerfect program and they have a different list of
Printer preferences to chhoose from and none of those allow me to print
either.  Whenever I attempt to print via WP or Cli, my system crashes.

If you have the Pan{sonic KX-P4410 driver,{would it be possible for me
to mail you a disk to send back?  Or is there an ftp site that has
drivers available to download.  Any help I can get on the matter would
be MUCH appreciated.  Thanks!

Hmm.. do I need to set the maxmem on Morph AND MorphPlus?  I set
MorphPlus's tooltype MAXMEM to 5000000.. and I have 6megs.  Maybe I
should lower MAXMEM to 3.5megs or something?  I wonder why it would
crash like this.  ADPro doesn't crash, it just complains that it's low
on memory.  BY the way, it seems that it's crashing on the Warp
operator, when it's warping a picture.. strange.

It depends on how much each picture differs from the previous. When your
camera approaches the table, large parts of the pictures change each frame,
and large amounts of memory have to be transferred which slows down animation
speed. There are some ways to avoid this problem:

- Don't use much (or any) dithering with the objects that change their
  position every frame. (When you move your camera, every object "changes"
  its position)
- Try to use a smaller color resolution (e.g. 16 instead of 32 colors)
- Don't move the camera (not very helpful in your case :-), only objects.

In general: keep the screen areas with changes from frame to frame as small
as possible, try to have big areas where nothing happens.

        Well, you could select a 256 colour WorkBench from Preferences, no?
Since I haven't seen WB 3.0, I can't say where in Perferences to set the

Organization: Massachusetts Institute of Technology

Date: Wed, 18 Nov 1992 21:59:57 GMT

Well, actually the answer is extremely simple...
  in order to save hard drive space and upload/download time, many files are put
together and compressed using special programs. These files usually end in .xxx
postscripts (remnant from DOS I guess). To get them back requires the same kind
of software, and this must be run on the program
  For example... to extract the files from an archive names hello.lha, you would
type the following

    lha -x hello.lha

    this uses the program (lha) with the extract instruction (x or e) on the file
(hello.lha).
  these programs are available in the public domain, and are very common. Here
are a few examples



  xxxxx.lha         :     lha
  xxxxx.zip         :     zip / zippy / pkzip
  xxxxx.dms         :     dms / dmswin - this compression only does full disks
  xxxxx.arc         :     arc / unarc  -  old and almost unheard of
  xxxxx.zoo         :     zoo          -  old and unheard of
  xxxxx.zom         :     zoom / zoomwin - compresses disks only
  xxxxx.arj         :     unarj (only uncompresses, haven't seen a compressor yet)
  xxxxx.sfx         :     this is just a self extracting archive of any type..
                             to decompress it, just run it.
  xxxxx.lzh         :     lha / lhunarc / lz / lzh  - older verion of .lha
  xxxxx.wrp         :     warp  - disks only


there are many more, and their names are usually indicative of the program used
to decompress them... look around, and you will proabably find what you are
looking for...

Dont buy PCMCIA ram expansions, use the trap door instead.  The PCMCIA

I have a Maxtor 213 SCSI low profile and a Quantum 120 LPS.
I backed up the Maxtor and did a low level format cause I had some funky
errors (my fault).  After I formatted it and restored it, I went and did a
test on it cause I noticed a considerable increase in performance.  I found
out the maxtor went from doing 900K/sec to 1600K/sec!!  All because I did a
different # cylinders, heads, blocks per track, and blocks per cylinder.
I have a question 4 u.  What is the maximized low level format config for a
maxtor 213 and a quantum 120 lps?  It definitely makes a difference.  I
forgot what it was, but here is my new maxtor config:
cylinders = 3055
heads = 1
blocks per track = 136"/usr1/users/research/ree88132/.article" 30 lines, 1111 charactersbl
ocks per cylinder = 136
reselection = off
What is reselection?  where (what cylinder) should I park my heads?
Thanks for the help.  Maybe we can gather a collective list of all HD types
for scsi, IDE, etc.  and post it.
PS.  My Quantum gets 2.2 megs/sec, don't know how much better I can do than
that.  I have an A3000 25mhz and use the SCSI bus on the motherboard.

The monitor may indeed be at fault, but it is not because of the border
color.  I am running BBlack and do not have the awful border on any of
the screens.

I have noticed this behavior on SVGA systems also and would guess that
maybe the different frequencies are causing this effect.  The dblNTSC
and dblPAL modes are around 29kHz instead of 31kHz and might be the
reason for the different levels of brightness.

but it won't tell you exactly what it is.

Subtitle:  Why buy a Quatum.

Here's my story:

I bought a used GVP A500 HD+ from comp.sys.amiga.marketplace.  The unit
had a 52 meg Quantum.  (The drive was actually an "Impulse Plus" drive --
the tag read "A division of Quantum."

The drive would occasionally spin down.  The GVP tech guy told me how to 
measure incoming power with a meter.  The power was good; the HD has a problem.
(Note on GVP tech support:  the gentlemen I have talked to appear very
competant.  They're number is not toll-free.  Be prepared to pay lots of
long-distance charges while waiting a long, long time for someone to answer.
Not to worry -- they'll play you strange new-age music while you wait.)

I called a myriad of Quantum 1-800 numbers.  They had a recording or an
individual who said the same thing, "Dial the Quantum 1-900 tech support
number.  And be prepared to pay $5.00"

I 1-900 number!  I tried to look on the bright side.  At least it's only
$5.00.  It's entirely possibly to incur more than $5.00 of long-distance
charges while talking to tech support using the conventional method.

From the serial number on the drive, the Quantum dude could tell me the
month it was made.  It was still within it's 2 year warranty.  I explained
how myself and the GVP dude determined it was the drive.  The fellow
didn't seem particularly interested in the explanation; he was immediately
prepared to have the drive replaced.  (Perhaps he recognized the drive as
a potentially bad one by looking at the serial number.)

He gave me an address to ship the drive to.  He said they'll send a brand,
spanking new HD with a new 2-year warranty.  Cool.  I haven't got it
yet.  We'll see what happens.  I don't have any reasons to belive they
will not follow through.
