I would guess a Watcom compiled version run through a decent code optimiser
would have a significant effect, as indeed would support for a Weitek copro
(which I don't have, alas).

I haven't been through the code in detail, but there must be a few loops
that could be unwound a little.  The sluggishness comes from multiplatform
code I guess.

I have heard of a Watcom version of POV, but so far been unable to track one
down, a nice chap said he would mail me one, but his address was rejected
by his domain's postmaster... :-(

Cheers
Andy.

I would like to collect the following infor regarding each format:
    1) data format name.   2) why it's popular    3) in what field.

Very touchy.  And very foolish.

I most certainly did not take the posture that you imposed on me.

I asserted an opinion, that being that freely available software
flourishes best when source is available too, at least on UNIX platforms.
Correction, I didn't even assert the opinion - I agreed with what was
already there.

I certainly did NOT condemn or slam their efforts.  I am grateful
and pleased to see ANY free software release.  There is no such
thing as a negative contribution in this arena, except perhaps
postings like yours.

I certainly did not start throwing profanities around -- you did.

In fact, I said nothing negative at all about the package.  I simply
state that it would be interesting to me if it had source code.  Since
it does not, PBMPLUS suits me just fine.

Actually, one of the interesting things about the package is that
it supports HDF.  I wish more utilities did.

Don't forget pbmplus *is* available in source code and does 99 percent
of what imconv does (and often does it faster!).  It's available with
the X11 distribution in the contrib directory or from your favorite
FTP site (wuarchive.uwstl.edu comes to mind).

I'm sorry I don't recall its title, but I know that there was a
software package (call it a game, if you must!) for Macintosh in which
the object was to train an on-screen dog.  A substantial amount of
dog-ness must have been programmed into this.  If you wish to pursue
it, I'd say a request in comp.sys.mac.apps and comp.sys.mac.games would
do the trick.

This is a VAST subject.  Several whole books have been written on it.
Some starting points are the formats supported by SDSC toolkit and
PBMPLUS.  They are graphical data formats.  Each discipline has its
own; a book that came out of a workshop we had last year lists quite
a large number: Scientific Visualization - Techniques and Applications;
Brodlie et al, Springer-Verlag 1992; ISBN 0-387-54565-4.  The 35
participants at that meeting identified over 100 formats that were
COMMON in the disciplines they knew.  Two discipline-independent formats
are NetCDF and HDF.

It really is a subject that is well documented in books and papers
from SIGGRAPH etc.., so I suggest you pull stuff from them.

Subject: 3D plotting / visualization
Organization: These opinions are mine!
Date: Mon, 14 Dec 1992 18:36:20 GMT


 I am about to tackle a data analysis/visualization project, and I'm looking
 for data plotting packages with the following characteristics (in approximate
 order of importance for my problem).

   o  Runs on a PC under Microsoft Windows.

   o  Must be capable of producing 3-D color-shaded surfaces and of rotating
      surfaces and coordinate axes to any selected angle/azimuth.

   o  Invokable interactively and by some sort of "macro" execution (so I
      can save my analysis steps, and modify them).

   o  Includes in its command set all the programming functionality to import
      data, build if/then/else, do/while, do/until, etc. constructs; has a
      full set of built-in math functions; has ability to fit/transform data
      to standard forms, etc. . . .

   o  Has ability to open/close multiple windows and manage 3-D contents in
      each simultaneously, decipher mouse-button actions and graphical cursor
      coordinates originating from each.

 I'm aware of the plotting functionality in spreadsheets, such as Excel, and
 they're not a good fit.  I've heard that a planned future release of Matlab
 (from The MathWorks), may meet many of these needs, but am looking for
 something NOW.  There is also a product called PV-Wave (from Precision
 Visuals, Boulder CO) that would be excellent, but it only plots to VAX and
 Unix display devices, and this project is limited to PCs.

 If you are aware of anything that you think would fit the bill, please
 e-mail to me and/or post.  (Please include a contact for the vendor or
 distributor if possible.)

 I'll post a summary if there is sufficient interest.
