I have been trying to use the tools discribed in the Advanced Topics section 
of the AVS Programmers manual with mixed results.  In particular I want to 
follow dynamic memory allocation for some modules I'm writting.  I've set the 
environment variables:
    AVS_MEM_CHECK=1
    AVS_MEM_HISTORY=1
    AVS_MEM_VERBOSE=3
and compiled my code with MEM_DEFS_ENABLE set.  What I expected to see was a 
listing on standard out each time I called "malloc" with size info and address.
Instead all I see is a summury report telling me each module allocated "0" 
memory, freed "0" memory etc.  Any ideas what I'm doing wrong.

Hi,

I am trying to visualize some datasets (UCD data) using avs and have come across 
the following problem:-

I need to assign specific values to colors instead of the default avs behaviour
of mapping the lowest value in the dataset to the "lowest color" and highest
value to the "highest color". So basically I want to *fix* a numerical range to
the color range and want to see the dataset using this color legend.

Any pointers on how to do this will be highly appreciated.

Thanks.

X-Newsreader: NN version 6.4.19 #3



[This was taken from a e-mail message to a small group of those
 who were already interested]


Greetings!

After I send out this message, I will then post a call to several
newsgroups known to harbor i860/Oki/Stardent users to see who else
is interested.  Of course, everyone else is welcome to find as many
others as they may like.  As to the structure of how people can
easily get to others, we (Torin and myself) are discussing both
the notion of a listserver (if there are not many people), or
perhaps a newsgroup 'comp.sys.i860' or 'comp.sys.oki' (since most
so far seem to be owners of Oki or Stardent OEM'd Oki boxes).
Comments are of course welcome.

OK.  Enough of the really boring stuff for now.  The idea of
this group so far is to provide a means for getting software that
works on these boxes around (and general i860-based software
tools), but also since there seems to be a growing consensus
amoung those OkiStation 7300 / Stardent Vistra 800 users that
the whole software setup on the machine has many weak points,
to the point of replacing most or all of it.

Towards this goal several of us so far have been mulling over
the idea of how to get:

   1) a better compiler!

           (the current compiler, and even GCC, does not take
            care of i860 optimization well at all)

        There are better ones, particularly the PGI FORTRAN
        compiler...  but that one, for example, costs (I think)
        over $2000 !!!  Which in many cases is nearly as much
        as several of us paid for Oki/Stardent boxes.

        The advantages could be performance improvements by
        several factors particularly in floating point
        inner loops, which many people want to use this
        chip for in the first place.

   2) other software & scientific tools.

        There are many PD tools available for a lot of machines, which
        would probably work very well on the Oki/Stardent (or just i860)
        machines.  I am thinking of image processing, simulation of all
        kinds, even graphics packages (usually offline stuff like ray-
        tracers such as POV-Ray or rendering packages such as SIPP).
        I think there are even some CASE tools in the GNU project that
        would be slick to port over.

 (This is a biggie!)

   3) OS upgrade?  (more like a re-write!)

        Currently, the Oki/Stardent users face the quandry of no OS
        upgrades.  The support is simply that we can buy the most
        recent release of the OS (version 3) whose only bug-fixes are
        for the PGI FORTRAN support (still probably useful ;-).

        The System V R4 that is on these machines has very weird
        interactive response (jerky, but quick), and some of the
        drivers (local SCSI, and serial ports) *suck*.  They are
        just bad.  I don't really know if that is the best they
        could do, or if they took the easy route out (the i860XR
        that is in these boxes has some problems with multitasking,
        which may be partly possible to overcome with careful
        coding).

        The suggestions for a real re-write that don't involve an
        impossible amount of work for a small group appears to be:

           a) Linux

           b) FreeBSD, NetBSD  (sort of the same thing)

           c) Mach 3.0 with the HURD servers

        There are advantages and disadvantages to each one in turn.
        Basically the general advantage of 'a' or 'b' over 'c' is
        that Linux and FreeBSD are pretty much complete, while
        the HURD servers are definitely not at this time.  An
        advantage of the HURD is that Mach supports multiple CPUs
        and Distributed shared memory plus some other things that
        the others will not support for a LONG time, if at all.
        (a note is that if you have the graphics accelerator for
        the Stardent, you could have as many as 3 CPUs to utilize).
        Another HURD advantage is that there has already been a lot
        of work (incomplete) on porting Mach 3.0 to the Oki boxes.
        There is another bit which suggests that the multiprocessing
        problems in the i860XR would be lessened with a monolithic
        kernel such as Linux or FreeBSD.

        Personally, I tend to lean toward the HURD, as I would like
        to utilize the extra features such as Distributed Shared Memory
        and the extra processors in the accelerator (we may be able
        to arrange to pick up a bunch of these pretty cheap!!), but
        any of these would be enough work that it is worth talking
        it out.

Anyway, I will send some more technical details in another message
this evening on what I have discovered so far with Mach 3.0 and the
HURD (and maybe some comments on Linux and FreeBSD), and the software
tools necessary to build them.

Later,

Hi everybody

I'm studying at Monterrey Institute of Tech at Mexico, I'm studying Computer
System Engeneering and need some good and interesting area of research in
graphics world, this investigation doesn't intend to be too wide, it's just
a little study about any theme in this area; there's just a little problem,
I can't take 'Virtual-Reality' or 'Fractals' related areas because for my
teacher those themes are too abstracts and difficult to take. if you hav
any suggestion of any good theme, I'll thank you more than a lot.

Hi, I am trying to put a surface over an AVS geometry. I have a skull on the
screen and I do interpolation over selected points. The result of the 
interpolation are points x, y and z. Now to cover the skull with this surface
I tried to read ii into a 1D field and then used bivar to convert it to
a 2D field and then put it through field to mesh and rendered and dispplayed it,
but this gave me a flat surface at a ninety degree angle to my skull. I'm not sure what the problem is  firstly, I want to know if I rotate my skull, and then pick the points over which to do interpolation does this change how the object is drawn afterwards. If I had to leave the skull as it appears on the screen will this change the results, by not putting the new surface at a ninety degree angle. We are using model coordinates to do the interpolation on.

The other problem I have is how to draw the results in order not to get
a flat surface. At the moment I am using bivar to convert my 1D field to a 2D
field and then field to mesh to convert the field to a geometry, however this
does not seem to be giving me a 3D surface. Do you have any suggestions???


I also have a file in the format 
  x 2 3 4
y 2 2 3 4
  3 5 6 7
  4 8 9 10

and I read it into a 2D uniform field by setting field I2D(*output,j,i) equal to 
2 if i and j are 1 etc. Then I tried to put this through field to mesh
and render it but it also came out with a flat surface. Does anyone have any
suggestions??

Could I possibly plot the xyz points and somehow get a surface not just little 
points? (Not using plot_xyz)

Thaks in advance

  Well, okay, so we lied ... version 1.2 wasn't the final version.  We
*did* say that we weren't *planning* on making another release, but you
know what they say about rodent and simian efforts at precipitating the
future ...

  Well we won't make that mistake again.  In fact, we have someone working
on an Explorer LIC module, so there may well be a version 1.4 in the near
future which includes that.

  In any case, Version 1.3 of our Line Integral Convolution (LIC)
software is now available.  This supersedes version 1.2 which was
released on August 11, 1993 via anonymous ftp and comp.sources.misc.  The
new software is available via anonymous ftp from LLL-CRG.LLNL.GOV
[128.115.1.1] in the directory pub/lic as the tar'ed compress'ed file
lic.1.3.tar.Z and the tar'ed gzip'ed file lic.1.3.tar.gz.

  The copyright terms are very liberal.  They basically amount to: ``You
have to give the Regents of the University of California credit if you
use the software and you can't blame us if anything goes wrong.'' Other
than that, have at it.  Specifically there is *no* restriction on
comercial use.  See the copyright notices for all the standard legalese.

  Version 1.3's primary change is the addition of parallel thread support
for SGIs.  The change has been made very cleanly and it should be very
easy to add similar support for any other shared memory multi-processor
platform.  In fact, since the SGI parallel support uses SGI's port of
Sequent's parallel programming primitives, the current version *may* work
on a Sequent right out of the box ... but we don't guarantee anything.

  The parallel threads change is Way Cool.  There's just no other way to
characterize it.  Since the LIC algorithm (see below for a description) is
so local, it fundamentally parallelizes at the cache line level (although
we picked larger tiles!)  In our tests on an SGI 4D/340 (4 33MHz R3000
CPUs) we saw speedups ranging from a low of 3.55 to a high of 3.84.

  In addition to the parallelization changes there have been a number of
simple additions and documentation clean ups.  There's now a ``spot
noise'' image generator and a simple GL based image viewer to the test
directory.  There's also a white noise generator to the avs directory.

  And now the promised introduction to LIC for those of you who've
struggled through this far wondering just what the heck it is ...

    The LLNL LIC software distribution is an implementation of the
    Line Integral Convolution algorithm.  Line Integral Convolution
    can be used to visualize vector fields and generate a variety of
    unique special effects.

    Vectors are visualized by convolving an input image along vector
    stream lines in an input vector field.  The result is an image that
    looks like the input image, but blurred in the directions of the
    vectors in the vector field.  For a thorough explanation of Line
    Integral Convolutions see ``Imaging Vector Fields Using Line Integral
    Convolution'' by Brian Cabral and Casey Leedom in the SIGGRAPH '93
    proceedings.

    This software system consists of a library that implements the LIC
    algorithm, a command line interface and an AVS coroutine module
    interface.

    Where possible, this software has been written to conform to ANSI C
    as defined in ANSI X3.159-1989 and POSIX 1003.1 as defined in IEEE
    Std 1003.1-1990. ...  At the time of this writing the software has
    been compiled and tested on HP Snakes running HP-UX 9.01, IBM RS6000s
    running AIX 3.2, SGIs running IRIX 4.0.5 and Sun Sparcs running SunOS
    4.1.1.  The previous version of the software also ran on DEC Alphas
    running OSF1; the current version should port to the Alpha platform
    without any major problems.

  We hope that this software proves useful to you.

  If you have any problems, comments, suggestions, bug fixes, etc.,
please feel free to contact us.  We're especially interested in ports of
the parallelization work to other platforms.  Note that any code you send
in should not contain any copyright more restrictive than the one we
use.  In fact, we'd prefer that you simply donate it and we'll put our
copyright on it to keep things simple.  We will give you credit of course!

bivar is _not_ the right tool for this job.  bivar takes a set
of points, and the assumption that there is some surface which
goes through them, and which can be described by a biquadratic
function which is well behaved.  this latter biz should ring
bells from calc 1 - one-to-one, single-valued, onto, etc.  the
surface of a skull is clearly not any of these.

worse yet, bivar gives you a field; the z-values of the function
at a bunch of (x,y) points that you specify.  

what you want, if i understand your problem statement, is a
bunch of geometry.  perhaps the folks from AVS would give you
some assistance in using their scat-2-ucd module which does
3D delauney triangulation (a "surface" from a bunch of scatter
points in R^3).  this is probably the best tool for this job,
at least in terms of tools that are available.

generating a (polyhedral, 3d) surface from point scattered in
R^3 is and has been a research problem for a long time.  i don't
like the results of the delauney method, myself.  each method
makes certain assumptions about the underlying surface, and what
is "best", and has this/these heuristic(s) woven into the
algorithm.

you'll have to do a fair bit of digging around, probably.  there's
no "easy" answer to this problem.

I want to call the graph viewer within a user defined module. 
In this example I want to
have graph veiwer plot the data contained in the file "input.dat" 
in an XY scatter plot.
The following is the sequence of commands in an AVS module written
 in F77 that I attempted. 
Some commands worked, while others did not. 
The data is plotted as Y data, not as XY data. 
Is the order of the commands incorrect? 
Should the commands be given in a paricular order?
Is there more documentation on AVS graph commands than given on
pages 5-38 to 5-41 of the Developer's guide?
I noticed that network files give commands to the graph viewer with
a "mod_graph" command. Can this command be used in a module via AVScommand? 
Where is the documentation for this command?

Does anyone have any modules (source in C) *or* helpful

Any information or suggestions would be greatly

Dear netter: (especially Wes Bethel of Lawrence Berkeley Laboratory)

Recently, I want to try the "scat3d" module from the avs ftp site.  However,
I ran into problem when try to compile them on my SGI machine (Iris Indigo
Xs24 4000).  In Mr. Bethel's code, I define "#define STARDENT800 1
", but when I go ahead to make the module, I got the following message:

------------  quote --------------------

Stop.
-----------  unquote -----------------

The problem is, no matter what I did, I can NOT find "s_wsfe", "e_wsfe",
"do_fior4" and "do_fioi4" everywhere.... NOT in the source code, NOT in
the fortran library, NOT in the c library. Therefore, I have no idea how to
compile the module right.

I am sure there are many netters who has used "scat3d" and compiled it
successfully on various platforms.  Would somebody kind enough to elaborate?


Thanks in advance

Is there an easy way to generate streamlines
for a two dimensional data set? Using the
3D streamline module generates non-continuous
segements, but in 2D streamlines are effectively
contours of a scalar value. Is there a PD module?

I have just started to do some programming for AVS. So I looked through
the modules on the ftp server. I downloaded the module duplicate_geometry
so I could look through it. In this module a function is used that is not
in the documentation we have (I prsume standard docs, User Manula,
Developers Guide...)  the function is
	GEOMset_new_edit_function() 

My question is are there more functions like this, and where would they
be documented, or am I just to dumb to find it.

If I'm not mistaken there is a Wais module on the AVS archive site 
(avs.ncsc.org) complete with source code.  Since Wais can get 
files from remote internet sites you're sure to find one possable example.

Hello,

When saving a network to a PostScript file (or printing it directly) using
PrintNetwork, it seems to generate a corrupt PostScript file. Previewing is ok
but printing gives strange results. 	

Probable cause: there is one more grestore command than gsave commands.	

When we delete the last grestore (grestore %Page) the file can be printed.

Is this a bug or a feature ?????

I am having difficulty using the modules for extracting mouse info from
the image viewer.  For example, if I read in a previously working network
which uses one of these modules and send the data, I can never get the 
module to respond.  I have tried pressing the left mouse button to 
select the image and then the set pick mode button on the module as well
as selecting the module in the pick area of the Image Viewer.  If I hammer
the module and bring down a new copy it will now work.  In addition, if
I bring up an additional Image Viewer and image_probe module, then I
will unable to get attention of the previous image_probe module.  I am
using AVS5 on a SS10 with Solaris 2.1.

I am also looking for a method to overlay one image over another and then
use the mouse to move the foreground image.  Does a module or network
capable for accomplishing this exist?

We have datasets which we decompose intentionally into several parts,
essentially a fracturing of the data.  The connectivity of each part
must be consistent.  We do not move any of the parts with respect to
each other.  The UCD data still appears unbroken with the data for
each member following the next, but the visualization shows individual 
members.

Tim,

possibly a better solution to the idea of generating multiple ucd's after 
fracturing would be to use the ucd structure 'material type' variable. 

If when you create the ucd, if you 'AND' the UCD_MATERIAL_IDS flag to the 
'ucd_flags' variable (on the UCDstructure_alloc call), the ucd will be created 
with an integer array, the 'material_type' (sizeof number of cells in ucd),
which can then be used to flag some cells as belonging to one group, others to 
another and so on. The ucd_to_geom AVS module utilises this - if you use this 
module you will notice that there is a toggle named 'Explode Materials' 
complete with a 'Explode Factor' dial. If you assign different material id's to
each cell, 'Explode Materials' would blow the rendered model into its 
constuant parts eg cells. 

This may (?) prove a more manageable solution than generating multiple ucd's
as this way you are not limited by the number of ucd output ports you assign, 
so therefore to that number of fracture elements.


Hope this helps,

Peter Yerburgh

This module should do just the trick:

Name        : animate_file    Version      : 2.000     Mod Number : 1135
Author      : Terry Myerson, International AVS Center (NCSC)
Submitted   : 02/24/92        Last Updated : 11/04/92  Language   : C
Module path : avs.ncsc.org:avs_modules/data_input/animate_file
Ported to   : IBM Convex Kubota Sun HP
Description : anim_fname is used to output a series of filenames for input
              into a reader module. The module inputs an integer and a
              filename base, and output a filename in the form
              "$base.%3d". This module is very useful for a series of
              files containing a time series of data. Bug fixes and
              extensions for version 2.0 added by Wes Bethel, LBL.

Good luck with it.

Subject: polytriangle strip rendering

Greetings,

I'm having some trouble getting proper rendering of polytriangle strips.
It seems that part of the geometry has normals inverted.
This results in patches that are very dark.
I'm fairly certain that the normal data is correct.
Creating a "normal object" with geom_to_normls looks fine.

The problem seems to be related to either the orientation of the
first polytriangle in the strip or the "parity" (odd vs even)
index of the vertex.  My observation is that adding some duplicate
(dummy) triangles can change the normals for part of the strip.

Why is the normal data insufficient for proper rendering??

I think that the most straight forward way is to look at the module at 
the International AVS Center called something like "animated filename". 
This module will let you specify a series of files with some incrementing
numerical componant (like file.001, file.002, file.003, etc.)

The challenge is to also WRITE the files, implying that you'd need two
of these modules (one for reading the new data in and one for writing the
image (or whatever) out).  The reading module should be a co-routine (or 
driven by a co-routine liek ANIMATED INTEGER) and the writing module
should be a subroutine module so that the modules work synchronously
rather then getting out of step with each other. 

Another option would be to drive the number part of each name from a
common module (like ANIMATED INTEGER).

Was that clear or did I skip too many intermediate steps? The summary
is that this is easy, look at the ANIMATED FILENAME module at the IAC's 
ftp site, and you have several options available to you for syncing
things up.

Of course, you could just write a script with the CLI (yet another option!)

When the normals for polygons are not supplied, we derive them 
by assuming that they are ordered in a clockwise fashion.  Clearly this
assumption is sometimes wrong and results in pictures where all or 
some of the normals are "backwards" resulting in geometries where 
the light seems to be behind some or all of the polygons.

If ALL the normals are backwards, then you use the FLIP NORMALS module
or the GEOMflip_normals() library call.  If some of the normals are
backwards, the easiest work-around is to use bi-directional lights.
The only real disadvantage to this is that your specular highlights
will still be screwed up.  

The only real fix is to run through your geometry as you are building
it and order the verticies so that they are clockwise with respect to 
"out" (which could be pretty ambiguous for many surfaces).

Can some one look at the following module, and tell me why the

Greetings,

I don't think this fit exactly into this newsgroup, but
I did not see one that was more appropriate.

I am looking for a presentation quality graphing package
for generating 2D XY plots and runs under UNIX.  These sorts 
of programs are very common on MSDOS and MAC machines but
I have not seen any WYSIWYG graphics packages for UNIX.  

The only program close to this is xmgr.  I have found it difficult
to use and without any help screens it is slow going.  All other programs
I have seen thus far are text driven, not WYSISYG. 

If you know of any programs that might fill the bill please
let me know.  Thanks in advance.

Summary: Query: easy canned way to plot points on sphere?
Keywords: plot points on sphere surface


AVS users,

I have a reasonable amount of experience visualizing 3D uniform scalar
fields using AVS (slicing, isosurfacing, etc.), but now I would like to
do something completely different:

I have a simulation whose output is points on a sphere.  That is, it
follows the motion of points confined to move on the surface of a
radius-1 sphere, and outputs their final positions.

Does anyone have any suggestions for how to plot the radius-1 sphere as
a geometry with the points rendered as something like tiny spheres on
its surface?  I need to be able to rotate the whole thing rigidly as a
single geometry, and make the surface of the big sphere translucent so I
can see the small spheres on the backside of its surface through it.  A
geometry defined as a big sphere with a collection of small opaque
spheres in the right relative locations would seem to be ideal; then the
geometry viewer would allow rotating it, setting translucency properties
for the big one, etc.

Is there a way to do this easily, ideally with the canned AVS modules
that come with the system?  Any suggestions or outlines of possible
networks would be greatly appreciated, as would advice on how to write
out the data for READ_FIELD (or whatever AVS data-reading module would
be best-suited).

Right now, the simulation outputs only the two angles from spherical
coordinates for each point.  It would be no trouble, of course, to
convert these to (x,y,z) coordinate values or whatever is best.  The
number of points is small, generally not larger than a hundred.

Well, the AVSinput_changed function is not defined the way you think.  The 
parameters to the function are the port name, and the connection number, not
the port number.  For instance, in your first printf, you are asking if the 
first connection (0 in c programming) has been changed, but in the third 
printf you are asking if the third connection _to_that_field2_port_ has
been changed.  And since you can only have one connection to an input port in
most cases, the input doesn't exist and therefore hasn't changed.

At least that's the way it is described in the Developer's Guide.  I don't
know why the second port is working fine.

Hope this fixes it.

Boy I love questions I can answer!  For C code, the second argument to 
AVSinput_changed should always be '0':

:         printf("\ninput field1 = %d\n", AVSinput_changed("field1",0));

should be:

:         printf("input field2 = %d\n", AVSinput_changed("field2",0));

Tim,

The combination of the 'bubbleviz' and 'scatter dots' modules appears
to do exactly this.  Essentially, you create a "field 1D 3-space irregular
4-vector float" and feed this to scatter dots which interprets the 4-vector
as [radius, R, G, B].  In the previous description, "1D" means a 
simple list of data elements, "3-space" means that each data element
lives somewhere in a three-dimensional cartesian space, and "irregular" 
means that you are supplying an explicit [X, Y, Z] triple of that 
location for each data element.

See the on-line demos of Bubbleviz in the demo suite for an example.

In your case, your list would be one larger than the number of "small
spheres" and you would dedicate that extra location to storing the 
information for your one large sphere.  One limitation to this approach
is that all the spheres will be in the same geometric object so that if
you change the transparency for the big sphere, all of them will change.  If
this is unacceptable to you, then the work-around is to have two parallel
sub-networks of bubblevizes: one for the collection of moving spheres and 
one to simply produce the big sphere.

Good luck and send us pictures (or videos) if the results are cool!

I've written a a module which computes either a 3D or 2D
vector cross product.  You should be able to modify this
to allow the calculation of a dot product also.

It's posted below.

Hope this helps.  Let me know.

We are looking for a low cost solution for printing color AVS output.  Printers
that can do color PostScript (for example) seem to cost on the order of several
thousand dollars and prices for other kinds of printers can range up to several
tens of thousands of dollars.  However, there are things like color DeskJets
that are only a few hundred dollars.  There doesn't seem to be any AVS module
that can print directly to one of these.  However, there seems to be a great
number of contributed modules for generating all kinds of output formats, so it
seems that it should be possible to find some low priced printer, some AVS
module and perhaps some external conversion program (of the flavor of xv) to
make AVS plots.  Any ideas would be appreciated!

I would like to clip geometries lying within a bounding box, such that these geometries do not spawn outside this box. For this I created 6 planes, forming the sides of the cube, with the intention of using these as "clip planes".

I could not get the result I wanted. Only for couple of these planes, clipping happens;I tried geom_set_clip CLI command with various combinations of state option (inside/outside). Any suggestions ?

Thanks in advance.

I have a few simple things I'm trying to do, but have not yet found a way:

1)  How can I re-label the geometry viewer and image viewer windows to say
    something meaningful?  I want to change the window label rather than
    add a "label object" to the scene.

2)  Is there a way to stop the user from manipulating a camera?  The
    transform mode of an object can be changed to "ignore"-- I want to
    do a similar thing with one of the cameras.

3)  Is there a CLI command which allows me to get the camera params from
    within a module (in particular I want to get the Window Size and
    Camera Scale).  There is no geom_get_camera_params command listed in
    the manual.

4)  Is it possible to create an input port which will take more than one
    connection from upstream modules?

Any hints would be appreciated!

who use AVS for this type of work and was wondering just how many there are.
The various modules in the CHEM kit + the data structures are not really geared
for large molecules and there's not alot in the module depository - I don't want
to re-invent the wheel, if someone has hoards of Mol. Biol. modules just waiting

I wrote a module a few years ago for AVS 3.0 to produce a scatter-data field
which described a sphere of points. I used these as basis points for particle
advector so that I could release a sphere of point charges around a molecule.
The sphere distorted in the molecule's electrostatic field - this produced some
great images when used with the tails option in part. adv. (I also wrote a
module to import DelPhi electrostatics and mol. surface data for this purpose).
The sphere module allows the radius and point density to be changed etc.
I always meant to put these in the avs modules depository but never got round to
it. If anyone's interested I could post these.

so expensive :-) ).

However...
For polytriangle strips, (as opposed to polygons), I believe that the ordering
of the triangles changes as you go down the strip.  That is,
the handedness changes for each triangle.  The first is clockwise,
second counter-clockwise, third clockwise, etc.
Does AVS require that the first triangle of the polytriangle strip
have clockwise ordering INDEPENDENT of the vertex normals??
The vertex normals should be sufficient to properly render the triangles.
However in AVS5 on several machines, this is not the case.
Bi-directional lighting does look OK however I still don't understand
how the vertex normals are used.  What assumptions are made about the
polytriangle strips?? More importantly, why are vertex normals insufficient??

Hi everybody!

I am using AVS quit frequently on Sun and SGI.

When doing Animations on SGI I get after a certain number of steps
(in the order of 100) the Warning

   overflowd shm id table -- may loose shmsegments

This is then repeated for basically every operation I do within AVS.
Up to now this did no harm to my animations, but seems to slow down
the computation, and anyway nevertheless I don't like warnings.

Maybe anyone could give me a hint.

Or maybe some AVS people could grab this message and look for a
bug in AVS. (From the man-pages I understand, that the shmid is 
integer*4 and should be freed by the application using it)

I do  n o t  have this problem on Suns !

Joachim

PS.: What would be the right place to report AVS bugs ???

We have a frame by frame recording system to produce video animation. Images are generated with scientifique packages like AVS, MPGS, DISSPLA, PHIGS...
We have already done few movies, with difficulties at the beginning, but now without hardware or software difficulties.

Now we would like to improve the quality of our scientific movies. Video is lower quality than computer screen, and we need some basic recommandations to produce video movies like :
- some colormap exemples, or which colors or colors combination not to use;
- how long to stay on each sequence ;
- line width and color to avoid video aliasing ;
- fonts size for titles ;
- ...

I didn't find any books or articles on this basic subject. I only find technical books on colors, video..., but never practical recommandations.
I know that knowledge comes with experience, so thank you in advance to share with me your experience in doing video animation.

I'm  sorry if this is an faq but our group needs several converters
and hope they are available somewhere. These are:
tiff to avs, PCI to avs (where pci is an remote sensing software
company) and ERDAS to avs. These would be image converters. 

What is the ftp site for avs software if it exists?

Is there a faq list?

Thanks for all your help.

Doug

Does anybody know where modules for reading in finite element meshes
in standard formats such as NASTRAN may be found?

Hi,
	Myself and some of my co-workers are interested in plotting
elevation data.  The data is 2D (x,y and elevation value) and we 
want to plot the elevation surface.  The data is irregular. (i.e.
x and y are irregularly spaced).  Any advice??????

Thanks in advance.

To date there is no Uniras newsgroup set up, although no doubt
some postings to comp.graphics.avs will be read by Uniras
users.  However, FYI, the contact info for the main Uniras
office is:

AVS/UNIRAS
Montrose House
Chertsey Blvd
Hanworth Lane
Chertsey
Surrey  KT16 9JX

Tel: (44) 932 566608
Fax: (44) 932 568842

Enjoy,

PS  Would you be interested in sharing your AVS work with the
scientific visualization community worldwide via a short article 
and / or slides in an upcoming issue of AVS Network News?  This 
is the IAC's quarterly magazine made up of user contributed 
articles.   Thanks for considering this!

Hi Joachim,

You will need to increase shared memory segments on your SGI.
Off hand, I'm not sure how to do this in IRIX; you can check
with an IRIX manual.  Also, the code is the same between SUN
and SGI, so that indicates it is an OS problem on the SGI.

If you (or anyone else) has AVS bugs to report, AND you
have an AVS Support Contract, then email bug finds to support@avs.com

Enjoy AVSing!

Lou.

xi yi ui vi

xn yn un vn

I would like to draw n lines. The i th line should start from (xi,yi)
and end at (ui,vi).

Could somebody please tell me the convenient way to do that
within AVS?

Your help would be greatly appreciated.

I have the same problems and have wrote some program to get the terrain into
2D field data format.  I assume that you have the data sorted by longitude and
have extract number of columns in each row. The format of the data is:

(long, lat, elev) in (F16.8, F16.8, F16.8)

if you have the same data format, please contact me. I will be happy to share
my program with you

Hi Folks,

Yesterday I made a quick posting about Uniras. The office I gave you 
in the UK is actually the AVS/Uniras office for the UK, not the 
main Uniras office as I reported yesterday.  Sorry about this mistake. 

AVS Waltham is the headquarters location for AVS Inc.(which includes
AVS/Uniras):
	
        Advanced Visual Systems Inc.
        300 Fifth Ave.
        Waltham, MA  02154
        USA
        Tel:    617-890-4300
        Fax:    617-890-8287

  They have sales offices throughout the world with major
subsidiaries in Copenhagen, UK, Italy, France and Germany.  

In Copenhagen they keep most of the previous Uniras headquarters operation in
tact with sales, marketing, support, administrative and R&D resources
located in Copenhagen.

-Steve
