  Hi Guys,
        I had a question. I am working on a project involving
graphical user interface (GUI) developments in C++.
The top priority in this project is the portability of the developed
application on to platforms such as Windows, Windows NT, Motif(unix) and
presentation manager (OS2). As a first step my job is to
survey and order a portable GUI application framework or toolkit
(software). I have made a survey and converged to 4 different
packages namely

1) Open Interface by Neuron Data
   ______________

2) XVT by XVT Software
  ____

3) ZApp by Inmark Corporation  and
  _____

4) C++/Views by Liant Corporation
   _________

I am interested in knowing which of the above is probably the
best software (Cost is of no factor) and also would appreciate
If anybody can let me know of any other alternate software better than
the above mentioned softwares. I would also like to mention that
the application I will be developing is in C++ and hence need the
GUI package best suited for this language.

Any suggestions will be greatly appreciated and
can be mailed to me at
rajsnr@iastate.edu

I suggest that you read the raster file directly and decode the
run-length encoding yourself. It is fairly straightforward and a good
example can be found in PBMPLUS (look for rasttopnm.c).

converted file, not just look at it, could be tough.

If you think this is of general interest, could you elaborate? Or is
there some publicly available document that would explain things
related to the issue?

Some elaboration on this also? I think the traffic in this group isn't
excessive. I'm sure these things are evident to the persons who
designed VGX, Elan and RE but to me the reduction in performance is a
mystery.

Do you think that some applications will take a performance hit when
ported from GL to OpenGL (from the fact that there is no swaptmesh()
equivalent)?

I may seem insistent on swaptmesh() but basically I would just like to
know about the issues involved. The applications I have in mind are
two very different ones. One would draw a lot of triangles and try to
draw them in as large trimeshes as possible. The other would callobj()
a lot of objects which could be drawn as single trimeshes if
swaptmesh() were available. Without swaptmesh() the objects would have
to be broken into several trimeshes. Can you estimate whether the
performance hit in these applications would be significant?

I've received some phone calls and other questions about when
OpenGL documentation will be available.  Here's an update.

Addison-Wesley is publishing a 2 volume set, a Reference Manual
and a Programmer's Guide.

The Reference Manual is NOW rolling off the presses and should
begin hitting bookstores in January, 1993.  I have a copy of
the book on my desk!  The Reference Manual has an overview, 
the man pages, and a way informative poster of the OpenGL state 
machine.  The cover of the Ref Manual is predominantly blue.

The Programmer's Guide is still undergoing internal review.  It
has not yet gone to the printers, but we have first drafts of
every one of the 13 chapters.  We (the authors) are confident
that the Programmer's Guide should be hitting bookstores this spring.
The cover of this book will be predominantly red.

Any more questions?  Ask us!  Thanks again for your patience and
support.

Not necessarily.  Our experience with implementing swaptmesh() on our
own machines is that it is easy and straighforward on pipeline machines,
(such as the GT for which it was designed) but difficult and complex on
the more parallel machines that we have designed more recently (VGX,
Elan, RealityEngine).

We agree that the savings aren't very great.  We decided, when we were
designing the OpenGL, that the savings in vertexes wouldn't be worth the
cost in both implementation complexity and the likely overall reduction
in implementation performance.

Yup, and a blatant one at that!  The NOTE is correct, the ERRORS entry
is wrong.  EdgeFlag would be useless if it could not be called between
Begin and End.  Thanks for calling this to our attention.

For those who attended and signed up last May, I am personally
responsible for getting you a free copy.  However, the survey
you filled out only entitles you to a free copy of the 
Programmer's Guide (the red book).  That's the book which is
coming out this spring.  In the meantime, the Reference Manual
(blue book) will be available, so you shouldn't hesitate to buy that
book.

If in the spring, you haven't received your red book, you know
to holler at me.

Does anyone know how color and otherobject attributes are handled in

Hello,
     as far as I know Wavefront are not too keen on giving the texture
info away. I know people who have looked for the same information and they
were not able to get it. .obj files don't have color attributes, they have
the material and texture attributes file names saved with them. You can
edit this with VI or some other editor as long as you save your models as
ASCII and not binary. By using the editor it is also possible to animate
the textures and materials (that is, editing the .mat and .mtl files).

Organization: Hewlett-Packard, Fort Collins, CO, USA
Newsgroups: comp.graphics

To whom it may concern,

Those looking for a way to run HP-PHIGS in a Motif environment now have a 
solution!

HP-PHIGS 2.3 on HP-UX 9.0 using Motif 1.2 provides a new Motif Widget called 
"XgPhigsDraw" that creates an PHIGS workstation that is attached to a Motif
DrawingArea.

HP-PHIGS MOTIF WIDGET: XgPhigsDraw
----------------------------------
    A new Motif 1.2 widget has been added for HP-PHIGS that will provide
    the following assistance:

        - Automatically opens a HP-PHIGS workstation inside of a Motif 
          DrawingArea widget
        - Handle resizing the workstation when the window is resized
        - Redraw the workstation when the window is exposed
        - Set the Window Manager colormap priority for the HP-PHIGS colormap
        - Close the HP-PHIGS workstation when the Motif widget is destroyed

    An example HP-PHIGS application using the new widget and demo program
    explaining the different options can be found in the examples (i.e.,
    /usr/lib/phigs/examples/Xg) and demo (i.e., /usr/lib/phigs/demos/Xg)
    directories included in the HP-PHIGS 2.3 Programming Environment
    product.

    Please refer to the "HP-PHIGS Workstation Characteristics and
    Implementation manual" for HP-PHIGS 2.3 and the XgPhigsDraw man
    page for more information.

It has it's own set of X resources that can be set to specify visual depth
and the necessary color environment.

The source and makefile for the XgPhigsDraw widget, as well as, two complete 
examples of how to write HP-PHIGS applications using the widget are shipped
with the HP-PHIGS 2.3 release.

Hi,

    I have some questions below on the Matrox MG-3D Ultra SXCI
graphics library.  Would appreciate if someone could answer these.

    I would also like to get in touch with anyone who is doing work
using the SXCI library.

    Thanks!



1) In SetLightSource, if a POSITIONAL_LIGHT_TYPE is specified, there
doesn't seem to be any effect.  The same goes for SPOT_LIGHT_TYPE.
Only AMBIENT_LIGHT and DIRECTIONAL_LIGHT seems to be working.

2) Under RendPolyQuad, when are the OptVertexColor fields used?  The
GOURAUD_COLOR and FLAT_COLOR mode do not work (just get a blank).  

3) Is there any way we can specify unique colors for each vertex?  I
suppose the answer will be to use the OptVertexColor, but when are
these fields read (under which mode)?

You could try XGKS, it's a GKS library which runs on top of X11.
It's probably available from several anonymous FTP sites, although
