We are in the process of aquiring a SGI Indigo R4000 (8bit color) for
our lab. Since we are depending a lot on Khoros to function properly on
the new machine I would like to know if there were any problems
encountered with Khoros on that platform. Actually, given the case that
Khoros will not work properly on the machine
I expect many hands with a tight grip around my neck. Therefore I would
appreciate any positive and negative 
comment.

Thank you,   Klaus Mueller

I'm sorry if this ends up being a re-post, but the question I sent to the e-
mail didn't seem to end up on the newsgroup.

I am trying to convert a headerless, multi-image, binary file to viff format, 
using the raw2viff routine.  The example file has 8 sequentially stored 
images, and so I set the number of data bands to 8, the rows and columns set 
to the single-image values.  I left all of the other parameters at their 
default values.  (Note: using 1 data band, I can successfully convert a single
image file using these parameters.)  I run raw2viff in cantata, and the 
output file is created successfully.  When I try to run animate to display 
the resulting sequence, it informs me that my viff file contains only one 
data band.  What am I doing wrong?

Any help will be greatly appreciated.  Thanks in advance.

Subject: Problems (solved) compiling Khoros with shared libs on Sparc
Organization: CSD., University of Erlangen, Germany
Date: Mon, 23 Nov 1992 08:48:50 GMT

I have tried to compile Khoros 1.5 on a Sun Sparcstation2 with shared
libraries, primarily to save disk space.

There were several problems, which were nontrivial, so I'd like to
share my solutions with other people trying the same thing.

First of all, the make system is not really made to support shared libs,
the problem is that a program using one routine of a SHARED Library
will need all symbols open in this shared Library, not only the
symbols used in the routine from the shared lib.
That means for example that every program that is linked to the dynamic
version of libgeosurf will need liblinpack as well, because there
is a routine in libgeosurf, that needs linpack.
Consequently practically all routines need linpack, eispack and fortran
and math libraries. 

Some of the Imakefiles un-cleverly define out "VEXPR=" which for
the above reason makes the Makefiles fail.

It is important to have the right Version of the Fortran lib, 1.4.1 works,
1.4 does not. It says "undefined symbol _MAIN_".

It is equally important to link against the right math lib, use the one
that comes with Fortran.

The math lib does not exist in shareable form (why not???), but you
can make a (bad) shared lib from it by extracting the objects from
it ( ar xv libm.a ) and linking it into a shared lib using ld (ld *.o).
Of course, use the math library from Fortran.

In the shared version of libXmu two symbols are not defined that are
needed by libXaw. Fortunately and strangely these symbols are defined
in an object contained in the non-shared version of libXmu, called
sharedlib.o. You can extract it, make a shared library from it and
link it dynamically to all modules requiring X.
The above is true for the X-Libraries coming with OpenWindows 3.0.

All things working correctly, your binaries will be 16-24kByte typically,
bin will be 9M with full debugging and symbols and 6M when stripped.

I didn't see an answer to this, so I thought I would offer my meagre advice.

When I had a similar problem, I found that clicking on the reset button before 
running the program did the trick.  This will ask the program to make new temp 
files.  I never did figure out why it can't find the old ones.

I hope this helps.

I have a raw binary (headerless) image file which consists of 8 seqential images.  If I
manually separate these into individual image files, I can use the raw2viff routine to
convert them, and then I can display them using putimage.  What I would like to do, however,
is convert them in a single step, and then use animate to display them.

I set up raw2viff to convert an 8-banded image, but when I try to display the result, I only have
access to the first image in the sequence.  What am I doing wrong?

Thanks for any help.

Subject: 1-D Time Domain Filters
Newsgroups: comp.soft-sys.khoros
Keywords: 1-D signal processing, filters

   I am using 1-D signal processing routines in Khoros and have run into a 
problem (or a lack of understanding) of dfiltbp (the Frequency Domain filter
design routines) and dfilter ( the 1-D time domain filter routines).

   Specifically, I have tried to create a bandpass filter using dfiltbp, 
with parameters:
                (Butterworth)
                Sampling Freq.      100 Hz.
                Lower Reject. Freq.   5
                Lower Cutoff  Freq.  10
                Upper Cutoff  Freq.  20
                Upper Reject. Freq.  25

This creates an ascii file for the z-domain transfer function for this filter.


   I then tried to use dfilter to apply the filter designed by dfiltbp 
described above.  According to the Help pages for dfilter, dfilter filters 
signals according to a transfer function which is input as an ascii file and
can be a z-domain function. (I assume of the kind generated by dfiltbp.)

   I tested this on a signals generated by dgsin and dgunif (sin wave and
uniform noise - the sin wave was generated with 100 Hz. sampling,
freq = 15 Hz so it should have been passed by the filter).  The results are 
absurd numbers (lots of really large numbers and NaN's), so I assume that
I am not using these routines correctly.

   Does anyone out there know where I've gone wrong?  Thanks in advance
for your help.

Use vsamp to sample your picture along a straight line. Make
shure that you set the Number of samples to a meaningful 
value, e.g. 256. The you can directly plot the output of vsamp
through xprism2.

I realize other people have replied about how to get F2C, but remember
if you are simply evaluating and don't care about the programs that use
fortran you can always compile without it.  All you need to do is change
your $KHOROS_HOME/repos/config/imake_conf/{machine}.cf file.

   Q26. How do I compile the Khoros system without FORTRAN?

   A26. Look for the line in your configuration (*.cf) file that says,
        #define HasFortran YES
        Change it to:
        #define HasFortran NO

        For those compiling on a SUN architecture, note that in the sun.cf 
	file for Khoros 1.0 Patch 5, there is an INCORRECT comment:
        /*
         * does your machine have fortran? If not comment the next
         * two lines
         */
	The comment lies.  Do not comment out the lines, simply make
	sure that HasFortran is set to 'NO' (not 'no' or 'No').

No recompiling necessary. Under xprism2 'Options' click
on 'relabel axes' instead of using the default 'rescale axes'.
Then you can do what you like with min,max and the intervals.

To create drawings of various sizes, use vgconst to create a background
of whichever size you want to have and use it as input to editimage.
To save your annotation drawings as a viff image, you must combine
them with the background image by clicking on 'COMBINE ANNOTATIONS'
under the 'IMAGE UTILITIES'-menu.

This seems to be a general problem with the algorithm for the roi bar 
colors. Currently the displayed roi bars simply have the inverted colours
of the image as it displays AT THE MOMENT OF ACTIVATING THE ROI. This
means that depending on your screen configuration, they might not at all
have meaningful colours when you enter the image with the mouse. You
can change this behaviour by hacking the routine 
$KHOROS_HOME/src/xvroutines/Lib/xvdisplay/roi.c around line 344.

(Hey Mark, do you read this? Sounds like the first drawing of the bars 
should be changed to occur on enter_notify of the raster image, right?)

Hope this helps,

\Peter

	Can you help me in solving the following problem on regular polygons.


    I am having a regular polygon with 
               
                     vertices = n
        degree of each vertex = d
 Number of edges in each face = f

 Is there any way to compute the number of vertices that are not adjacent
 on a deterministic machine. I deviced an algorithm to solve the problem
 on a non-deterministic machine which is not that hard. I am curious to
 know if there is a deterministic solution to the above problem. I found
 that this problem has very good application in Neural Networks.

 Is the problem NP-Complete ?

 Thanks

I am interested in knowing whether there are routines for getting profiles from
images.  What I want to do is to put up two points on an image and receive an
intensity profile (a plot of gray level variation along the path connecting the
two points).

If anyone is aware of any routines which can perform this task, please let me
know.

Thanks.
