Mail hsi@netcom.com - Image Alchemy, a comprehensive graphics conversion

	xloadimage 3.01 and xli (since it is based on xloadimage 3.01)
do 24 bit images properly. Whether they compile on the VAX under VMS
I have no idea.

   If I were just starting out, and had no previous experience with any
of these programs I would probably go with 3D Studio. It is the only one
of these that is currently being developed at a reasonable pace. Topas
is Crystal 3D with a more interactive face grafted on, and GSL (the
former graphic software arm of AT&T) believes in tiny improvments at
high prices. Digital Arts fired their tech support guy, and seems to
want to dump the PC product in favor of a product for the Indigo.

   Autodesk seems likely to be the most likely to offer a student price,
as they offer one on AutoCad. 

   Ease of use: Topas is the easiest to learn, and you can learn it
  in a couple of weeks. Problem is, at the end of two weeks you will
  know everything it can do.
       3D Studio is more powerful, and a bit harder to learn. It also
  has "hooks" for outside processes, so you will not have to depend
  on Autocad for innovation.
       Digital Arts is a absolute bitch to learn, dreadful manuals,
  but (IMHO) the most powerful of the three. I earn my living as a
  freelancer due to the difficulty of this program, so I have _very_
  mixed feelings.

      The student price for Autodesk 3d Studio is 395.00$  this is for any fulle
college student.  You can get it from the school or autodesk.  From what I haved
found out, is that it has all the same features as the 3K$ one.  It does have a
dongle tho.  I just got done playing with it at a conference at school.  Its GR!
Now I just have to come up with 400$ to get the damn thing!

This problem isn't stated sufficiently -- do you mean a fixed set of
sixteen colors, or a choice of any sixteen?

Cf. the Heckbert algorithm, and Floyd-Steinberg Dithering Algorithm
in the FAQ.

In the case of the former -- you are converting to a color LUT architecture
with sixteen entries -- you have both a color selection problem and a
mapping problem.  Simply treat the 256 color image as if it were a 24-bit
image, and  apply the Heckbert color selection, mapping, and FS dither.

In the case of a fixed set of colors, you must supply a mapping function
that will map an (R,G,B) value to one of the 16 colors.  Then map each of
the pixels using the FS dither algorithm as above, treating the 256 color
image as a 24-bit image.

        Call UK.AC.HENSA.MICROS (your mailer may want this reversed)
and use the Username hensa and Password hensa (both must be in
lowercase as it is a UNIX machine they use).

	The files you want are 

	micros/ibmpc/dos/e/e130/e130tiff.boo  
	micros/ibmpc/dos/e/e427/e427gif.boo  

(again all in lowercase). This is a BOO encoded file that is suitable
for transmission but will have to be deBOOed and then UNZIPPED before
you have the text.

        The necessary tools they can be obtained from the hensa.micros
site by downloading  

	micros/ibmpc/win/tools/deboo.c 

        which can be compiled to give you a deBOOer. You will also
need the PKUNZIP tool to uncompress things. Grab 00contents from the
tools directory and you will see the file names to grab which are also
BOOed!

Subject: Contouring of curvilinear gridded data

Reply-To: e-sink@uiuc.edu
Organization: University of Illinois at Urbana
Originator: sink@ux2.cso.uiuc.edu

OK, we've seen lots of messages about how to contour scatter data
by gridding it first.  My question now is about data that is
already on a grid, but that grid is NOT rectilinear.  Sometimes
I've heard of this kind of grid being called a warped grid.
Examples of commonly used warped grids include polar projections,
and Mercator projections.

The idea behind a warped grid is that each data point can have an
arbitrary X,Y position.  The X and Y values for adjacent data points
on the grid should probably have some relationship, but they need not
be rectilinear at all.

Such a curvilinear data set could be represented by three matrices;
one matrix for the data points themselves, and one for the X coordinates,
and one for the Y.

It would also be possible to represent this dataset as three columns,
X, Y, and datavalues.  This would eliminate the spatial ordering and
neighbor information, reducing it to scatter data.  However, then we
could place the data on a uniform grid (assumedly with some loss of
something) and contour it with normal methods.

Now I turn this over, hoping some experts will expound on this.
The above paragraphs give my [limited] understanding of this subject.
What above is incorrect ?  What else could be said ?

What is gained by contouring on the actual warped grid, rather than
making scatter data out of it, and contouring the uniformly gridded
version ?  Is this done very often ?  Is the algorithm difficult ?

Obviously, I'm not even sure what my question is.  I guess I'm
speculating that someone out there knows the answer anyway. :-)

Thanks in advance!

Subject: NURBS basis function on SGI's
Organization: University of Colorado, Boulder
Date: Fri, 6 Nov 1992 18:05:00 GMT

I'm a grad student at UCCS (The University of Colorado at Colorado Springs),
and I'm doing a NURBS project for my geometric modeling course.  We're using
some Indigo SGI's, and I'm running into a problem with trying to figure out
what the basis function should be.  Is this part of the Graphics Library and
can it be called somehow?  I'm thinking about using the basis function for
NURBS out of the Foley and Van Dam book, but I know that this one is
different from the one SGI uses.  In particular, SGI seems to handle the
case where the denominator of the basis function is zero differently than
it is handled in the Foley/Van Dam book.  Any help anybody can provide
would be appreciated.

I have received a 13584 x 19019 black and white image in 
PC Paintbrush .pcx format. I would like to convert it 
to a Sun raster file.

Yes, I tried using the Extended Portable Bitmap Toolkit and tried the
command "pcxtoppm" but I would need 775062288 bytes (i.e. over 775
Megabytes) of main memory for this conversion.

So, my question. Does any one have a program running under 
UNIX (perhaps written in C so that I can compile it easily)
to cut up PCX images into smaller PCX images.

Or, even better, does anyone have a program to convert from
PCX format to Sun Rasterfiles given a Sun 3 or a Sun 4 with 
32 Megabytes of main memory and given a 13584 x 19019 image?

Thanks,

I recently posted regarding what services were available for transfer of
high-resolution digital animations to 35mm movie film.  I received a
large number of _very_ helpful responses.  As I received 4 more in today's
mailbox I want to wait until after the weekend to post a summary.

We do computer animations on video, mostly for accident reconstruction and
scientific visualization.  We have a client who is very interested
in getting animations of their scientific data before a large audience
at science centers or similar environments.

Two rather interesting possibilities for this project are:

1) IMAX/OMNIMAX format (maybe even in polarized stereo 3D)
2) The Evans & Sutherland DIGISTAR planetarium projection system
   (Apparently this is a real-time non-stereo 3D-geometry system)

If you are a member of a company that:

  -- offers services for IMAX film format work
     (Digital image recording, processing, etc.)
  -- has made an IMAX or OMNIMAX film and has antecdotal info regarding
     production costs or problems with the format
  -- creates DIGISTAR presentations
  -- has had experience with DIGISTAR geometry formats, camera motion
     formats, etc.

please contact me.  Once again, I will post a summary of the responses
I receive.  Because we are trying to come up with possible budget ranges for
this project, I am particularly interested in pricing information
(approximate information is fine).

If you want any information you give me kept confidential, please tell
me so in your response.

If you want to FAX me price schedules (_very_ helpful), our fax # is:

  (515) 296-7025

Thank you in advance.

Peace,
