Hey!

I have a problem getting the right visual and colors for my application.
I wrote a Graphiktool to display Robotcells on an Evans & Sutherland
ESV 30 system, using PEX/PHIGS. Everything OK. I get as default a 24bit
visual with the right colors.
 
Then I tried to get it running on a SUN workstation. At that moment the
problem arised.

I used Sunphigs2.0 and Motif.
The problem is that my application gets a Pseudocolor visual as my default
visual, with unpredictable Colormaps.
I my application I use sets of three sliders (RGB) to create my colors. On
the ESV30 I could use the 24bit color mode to identify the color directly.
The Phigs part uses the Drawwindow (Drawwindow=XtWindow(drawarea); 
see code below) as the window to display the graphics. 
On a Sun I get different colors in my color mixer and graphikwindow.

The Application should be able to run on 8bit and 24bit color SUNS.
How can I manage that?

The approach to select the right visual and give it as argument to a 
XtCreateWindow() call does not solve my problem as I use Motifwidgets.

Please help me, as I cannot get the right information from the Motif and
Xlib books.

I have tried a few different approaches, as you can see in my source code.
I know that my application has been defined for the ESV30, but it must
be usable on sun platforms.

The problem with the visual does also exist on the E&S ESV30 machine when
I try to use a non default visual.

A request a few months ago did not deliver any good so I try another approach.
I will provide the source code to anybody who likes to correct the errors.

Any other use of the code of course only after my permission.
The code size is approx. 900K.


Send me a mail if you are interested.

I just bought one of Leading Edge's new Mini Tower computers.  It's a 
fairly nice machine:  486DX/33, 210M drive, 4M RAM, FLASH BIOS, 64K (to 
256K), CPU card (claims to be upgradable to Pentium).  The dealer told me 
that Leading Edge had been including ATI graphics cards in their machines, 
so I expected an ATI card in mine.  What I received was a Trident 8900C card 
with 1M RAM in a local bus slot.  I am not familar with Trident and the
docs are not very informative.  

Questions:
	Is this card accelerated?  

	It's a regular ISA card, so will I get any benefit from the local 
	bus slot?  

	There is no mention of what type local bus slot is in the 
	machine.  Is there a way to tell if it's VESA or some other type?

Hello,

I am looking for a display software for 24-bit raster files (true color).

It should run under open windows v3.0

   on a Sun SparcStation with GS frame buffer (which has 24-bit depth).

We are working with satellite images. Important for us are zooming and LUT-
manipulation functions.

Does anybody know a good display software which meets our requirements? Any

That's Brick Of Bytes, but we just call him "Bob" around here. :)
For those who missed the original posting, Bob is a real time
volume renderer that I wrote to browse large (e.g. 512^3) data sets.
If you are going to Supercomputing '92, stop by our research
booth (R20) to see it and other goodies in action.

Just ftp to:
	ftp.arc.umn.edu:pub/gvl.tar.Z

And you'll get the latest version of Bob, Icol and Raz.  Source, 
a manual, man pages, and binaries for IRIX 4.0.5 are included.

Bob is popular here, and I have been getting lots of good ideas and
suggestions for new features (e.g. lighting, explorer interface).  
Look for a reconstructed, better Bob in a month or two.

But first, back to Supercomputing '92...

Zeroth, neither Ken nor I are examples :-).

First, the "Trivial Accept" test does not even work for convex
polygons in the plane.  For he defined it in terms of minimum distance
from an interior point to a vertex:

	"Then let Prmin & Qrmin be the minimum distance from the 
	center[s] to any of the vertices of the polyhedra, ...
	Trivial Accept:  |Pc - Qc| < (Prmin + Qrmin)"

Let P & Q be squares, Pc & Qc their centroids.  Prmin & Qrmin are
radii of circumscribing circles.  The "Trivial Accept" condition
tests for the intersection of these circles, which clearly does
not imply the intersection of the squares.

Second, Pc and Qc are arbitrary: "let Pc and Qc be ...  arbitrary 
'center[s]' of the polyhedr[a]."  If Pc is very close to a vertex
of P, them Prmin is a fairly meaningless quantity.  Let P & Q be
triangles, and choose Pc & Qc to be close to a vertex of each.
Then the circles defined by Prmin and Qrmin are tiny, and it is
easy to arrange the "Trivial Accept" rule to fail without any
vertex of one triangle falling inside the other, and yet the
triangles can intersect.  I'd prefer not to draw this in ascii.
If you need an explicit example, draw these two triangles:

	(0,0) (1,0) (0,10)
	(-1,0) (1,10) (2,10)

Note that the failure of these ideas has nothing to do with
nonconvexity or three-dimensionality, as some have suggested.

Using a neat utility called 'xv', one can display many images in a sequence,
but in-between each image, a kind of crazy color scrambling occurs.  I'm
going to eventually hook a VCR to the output of a video card, so I can't
have this.  How can I get multiple images displayed on my Sun IPX screen 
without this happening?

I'm vaguely aware of some stuff like xgrasp and xflick, which show
.gl and .fli files, which show some good animation.  Is there anyway for
me to take a group of files, and put them together in this format for 
animation purposes?  Thanks.

I have a cyberware_demo avail at my ftp site which contains 3D human
head data and conversion utilities to convert the data into IGES
format, which you can then import into Alias. There are also texture
maps associated with the images which you can bring into alias also.


In order to get the Cyberware_demo via ftp do the following:

	1) ftp taurus.cs.nps.navy.mil
	2) login as anonymous, guest as the password
	3) cd pub/dabro
	4) binary
	5) get cyberware_demo.tar.Z

Once you get the demo onto your workstation:

	1) uncompress cyberware_demo.tar.Z
	2) tar xvof cyberware_demo.tar

If you have any questions, please let me know.

The one I had in mind was, two tetrahedra T0, and T1, where T1 is simply
a translated version of T0:

T0: 0 0 0    T1: 0.7 0.7 -0.5
    1 0 0        1.7 0.7 -0.5
    0 1 0        0.7 1.7 -0.5
    0 0 1        0.7 0.7  0.5  

If my mental 3D modeller is working (always a chancy bet), none of the
vertices of Ti are contained in Tj, yet the two tetrahedra intersect.

If you have a set of blocks handy, pick up two and arrange them so that
they contact in a single point, which happens to be at the midpoint of
two edges (one edge of each block).  Now push RealHard (but not
TooHard).

I personaly think the quality of VIVID is outstanding. But I agree with others
in that it requires a great deal of work to create tubular circular shapes ei;
the vivid scene produced by Stephen is beautiful, impresses me and everyone
I show it to. Looking into the script file for the method used to create the
tubular circular portions of the letter "D" shows a lot of hard work unless
one has a parcer to do the work.
	I am not being critical, I feel Stephen Coy has done outstanding
work on VIVID and VIVID2. It is fast and produces beautiful output of all
it's primitivies.

just my opinion, thanks Stephen,

Once again (everybody join in on the chorus, folks...)

	SIGGRAPH  <-->  Computer Graphics
	ACM       <-->  Transactions on Graphics

It't not that SIGGRAPH doesn't get along with its parent, ACM, it's just that
we publish **our** publications and they publish **their** publications, and
SIGGRAPH has no formal connection with TOG.  I can't begin to speak to what
TOG will or will not be publishing; for that, write to Jim Foley at Georgia
Tech.
