Hello,
       It is anybody can help me ?
       
       I have some picture who is comming from a confocal microscope 
       (BIO-RAD MRC-600) and I want to work with AVS.

       It is someone who as already made a filter or converter to translate 
       X Y Z pic for modeling for geom viewer

                                        Thanks

Hello,

there is a module for generating labels as geometries. You can
rotate, scale and do all other funktions of the geometry viewer
with them.

Name        : Vector_Label    Version      : 1.000     Mod Number : 1563
Author      : Charles J Williams III, Naval Research Lab
Submitted   : 12/30/92        Last Updated : 12/30/92  Language   : C
Module path : avs.ncsc.org:avs_modules/data_input/Vector_Label
Ported to   : HP IBM Kubota
Description : This module produces labels that are geometries. They can
              be scaled, rotated, and translated. Other geometric
              operators work as well, such as color, perspective, and
              material properties. The source for the vector
              information for the fonts is derived from the Hershey
              Fonts, stored in comp.sources.unix, volume 4, on your
              nearest archive site. The Hershey Fonts were originally
              created by Dr. A. V. Hershey while working at the U.S.
              National Bureau of Standards. The format of the font data in
              the Internet distribution was originally created by James
              Hurt at Cognition, Inc.

Here are my notes from when I tried to do the same thing:

     When you've finished editing a macro
     as per the User's Guide page 8-10ff,
     you need to save it.

     To save a macro, select Network Tools
     and Save Network and then you will be
     asked if you want to save just the
     macro or the whole network.

     N.B. The directory where it puts the 
     macro is the directory you ran AVS
     from!

Hope this helps.

                    Special Interest Group Meeting
                            SIGGRAPH '94

                               oOo

                      Tuesday, July 26, 1994
                          6:00PM - 8:00PM

                               oOo

This is an informal `panel-type' session to try and talk in general
terms about the current MVEs (such as AVS, Explorer, apE, Data
Explorer, Khoros, etc.), their uses, limitations and benefits, and the
future of such systems and others. In attendance will be people
(hopefully) representing all the main suppliers and developers of such
systems, as well as users, potential users, and interested parties !
The `panel' will probably consist of those involved in developing (or
having developed) such systems, and maybe some `power' users.  Everyone
with an interest is welcome (and encouraged)  to come along.

The `agenda' is very rough and flexible, as I feel that it is best if
the thing stays as informal as possible. If there are any comments you
have on things that you'd like to see, then please feel free to mail
me, or just ask at the time (for example, if any users feel they have
something that they would like to show that highlights a particular
issue ?) - I've got a classrom-type place booked (as opposed to a
boardroom or lecture theatre), so this should make it much easier to
keep things informal.

I'll post a fuller notice nearer the time of the people that will be on
the panel (any additional volunteers, especially to represent apE or
Khoros, just email me :-). In addition, I'll try and hire an overhead
projector - if anyone needs something else (video ?), then let me know
as soon as possible, as I have to pay for these things in advance
(aargh! - also, if anyone wants to fund some food/drink for the
attendees, then that would be great. Otherwise, I'll try and get
something organised).

Many thanks for all the interest shown, and support,
	-Gordon.

P.S. I'll try and keep some sort of record of what goes on - if the
thing is successful ! - so that those who can't attend get a feel for
what happened.

P.P.S. Thanks to Brian Blau for organising the room so quickly, and Len
Zaifman, George McGregor and many others for offering to help out.

INFORMAL AGENDA
---------------

1. Developers of MVEs (Past, Present and Future)
--
	* Brief introduction of some of the development people (on the
		`panel')

	* The relevant people *briefly* talk about their company's
	  product, new features, futures etc. ( this is useful in
	  letting users/attendees know what is available, but I don't
	  really want this to drag on - I would imagine each of the
	  companies present may want to leave some glossies etc. lying
	  around)

	* Each of the developer-y people might want to briefly state
	  what they see of as the future of MVEs (in general terms)

2. Informal Panel/Discussion 
--
	* Summary of the things which interest the audience, and their
	  backgrounds

	* General questions and discussion between all those present on
	  the present and future of such systems.  I hope that this bit
	  should take up the biggest proportion of the time, and that
	  the things discussed are not fixed. Some ideas, from myself and
	  others, could be :
		- what users want
		- what users can and can't do
		- what users like/dislike/use/don't use
		- typical problems
		- the data-flow model, and developments
			(e.g. AVS/Express, Explorer/ImageVision, Khoros..etc?)
		- how to make things portable
		- how to affect the future development 
		- advantages and limitations of MVEs
		- input & output to systems - connection to other apps
		- validation, verification, comparison, testing...
		- segmentation etc...
		- Use in medical and other safety crit. systems
		- futures ?
		- platform availability
		- `proper' parallel machine support (not just distributed
			computing, in other words :-)
		- system integration ?
		- open systems/cost of development ?

3. `Who's Best Discussion' Between Developers 
--
	* ONLY if there's time ;-}

4. Pub (optional) 
--
	If there is a local drinking establishment nearby, people could
	perhaps decant to this if they wish to continue `talking' :-)
--

Note that I don't think concentrating on individual products TOO much
will be useful, as there are SIGs for the specific products at this
SIGGRAPH and Vis' 94 (AVS (Wed. 4-6) and Explorer (Thur.2-4) at the
former, and Data Explorer at the latter).

I hope this meet will prove useful and interesting to users and
developers alike.

Comments etc to gordonc@epcc.ed.ac.uk.

See you there !

 I have set up the following network:

                        geometry viewer

Both sphere_to_geom and read geom have geometry outputs with 
disjoint lines, among other things like spheres.  When I
connect either of the two to the filter cylinder, or tube, 
the following occurs:
    Protocol failure:  Assuming module died, etc.

I thought the filters were supposed to accept the geom
data.  What am I doing wrong?

If you are using AVS 5 then you need to look in the AVS 5 Update manual
page 7-1.  The method for creating Macros has been changed.

I'm not sure about using other languages, but I do know that you can write
a module in C that will have a geometry as an input.  You can then connect
it to the isosurface output port.  Then your module can read in the 
geometry and extract the vertices.

Briefly, by way of clarification : INFORMALITY RULES...!

I'm posting this to try and emphasise and clarify  that
the arranged SIG meeting on Modular Visualisation Environments be as
INFORMAL as possible, and that what goes on be completely dictated by
those who turn up. 

Hence, in the announcement, when using the word `panel', I've always
tried to have it in quotes ! One thing that I hope people don't think
is that it'll be just another panel session, with `them' (the panel)
sitting at the front on a stage and answering the questions of `us'
(the non-panellers). Maybe I should have said it was to trying to be a
`Birds-of-a-Feather' meeting that starts with an informal `panel', and
continues in any way people want :-) 

The reason I thought an informal panel would be a good idea is that
there is a definite core of people who are `developers', and I thought
there would be interest in letting some of those (5 ot 6) BRIEFLY
describe their work, and what they see as the future. After that, when
it gets on to the main General Discussion bit, I feel that it should be
up to those who attend to `vote' what they want to do. Hopefully then
distinctions between users and developers should disappear.

One idea was to try and rearrange the seating to have an informal
circle/group or something, and then just write down a list of topics
shouted from those there, and perhaps including the things in the
announcement. Then we can just vote to decide what we want to talk on,
and talk away. The advantage is that the `panel' people, and other
developers, are still there to provide feedback on what IS available,
and to take on people's ideas. That, however, is just one `idea'..
Everything depends on how many people turn  up, and what they/we want
to talk about, (with the caveat that we stick to MVEs and such like, at
least loosely :-)

Hope this is clearer -if you have ideas for making the thing as
informal as possible, then please let me know, either now, or as I've
said before, by just turning up and saying/voting what you'd like to
do......  Everyone is welcome : users, developers, interested
people...whatever...the more varied the mix, the better.

	-G.

P.S. If all else fails, we could always engage option 3 (the pub), where
people can do and say completely what they please ;-}

I am not familiar with the full facts of AVS pricing, but it sounds as though
you may have been quoted for a floating license the first time ( many machines
but only one user at a time ) and for 5 fixed licenses the second time ( five
machines, one user per machine ).  I don't believe that AVS has increased their
prices that dramatically.

About AVS Animator: I haven't used it very much.  It's somewhat buggy, and I've
managed to crash it a few times.  It could really use an upgrade because there
are a lot of things that it cannot animate.

I would like to color a scalar data set with three discrete colors, say:
blue = lo value 
white = zero
red = hi value

Yes I read the module documentation on generate colormap, but still
can't do it.  Could someone help?  Thanks

Hi,
  I can't find anything in the manuals that explain what cell_tsize
and node_csize (arguments to UCDstructure_alloc) are, or how to
calculate them.  They are described as the "expected size of the
cell's connectivity list", and the "expected size of the node's
connectivity list" respectively.  I understand the concept of a cell's
connectivity list, but isn't that on a per-cell basis?  i.e. each cell
has its own list of nodes that it's connected to.  Is cell_tsize the
total size of all the individual connectivity lists, or something
else?
  As to node_csize, what is that?  If it's the number of cells that
contain that node as part of their connectivity list, it seems rather
hard to calculate.
  Is it necessary to fill in these two fields when creating a
structure?  Is it possible to pass zero to AVSstructure_alloc for
these arguments?

Thanks,
Kevin

Contour-to-geom gives me a nice color contour map of a scalar field. I want to 
superpose a vector field, created by hedgehog, on it.  Just putting them
together in the geom viewer causes many arrows to disappear.  My first
inclination is to make the background of the vectorfield transparent  -- which I

If I understand what you want to do, you would like a 10 foot wide graph which you can scroll through interactively.

Drop your data out in ascii coordinates then throw it at xmgr (ask archie where it is near you). That will give you a full screen overview into which you can zoom then scroll through the zoomed window. xmgr is a great piece of s/w.

If on the other hand, you need to interactively view the multiple outputs of the graph viewer, then you can pipe the output to the animator facility and play it back.

If anyone knows of an mpeg player that I can display full screen pictures, and EVERY frame (to hell with timing) with a nice scroll bar to control it, that would be a nice alternative to the animator, but I haven't seen one yet. If you find one, please let me know.

Failing all that, buy a video disk recorder eg Panasonic read/write optical disk

Good luck
Alan

Too many people ask the question backwords, e.g.
	(1) I've got the great visualization tool,
	(2) I have some data,
	(3) How can I visualize it?

The proper analysis is:
	(1) I have a scientific goal I wish to reach,
	(2) What experiment do I need to do and data to
	    to collect to reach this goal?
	(3) What is the best method of visual analysis
	    for this data?
	(4) What is the best tool to accomplish the data?

The people who ask the first way are hackers,
and the second way scientists.

Welcome to the club.....
Just in case a hundred other people don't already 
tell you. Try putting this in your c-code.

	#include <stdio.h>

	__ansi_fflush(ptr)
	FILE *ptr;
	{
        	fflush(ptr);
	}


It works! perhaps someone else could explain why.

Don't worry about it.
I have written a module outputting UCD structure and I set the 

cell_tsize = num_cells * 8; 	/* all hexahedra */
node_csize = cell_tsize;

It works and so I haven't further bothered to fix it :-)

It looks like you have connectivity info. for each cell. In that case, do
not think about : UCDnode_set_information
Just cut and paste it form the example given for read_ucd. Instead work with
UCDcell_set_information.

Now about some more experience (It may not be right. You are warned.):
If you are outputting a UCD structure do not forget to set the min and
max for the node values. Otherwise, it really confuses the UCD contour,
isoline and host of other modules. (ucd min max does not seem to do it
correctly.) On the other hand, you can blissfully ignore setting the 
min max for coordinates and these will be automatically calculated for you.

Best luck,

I beg to differ. Sometimes, it happens this way. I am having a chat
with my friend and he tells me what he is working on and shows some
of the results etc. And I think, heck, I can use it for my work for
such and such ... Show me, show me ...

Since the tool is already there I do not have to invest in additional 
resources (other than time spent in learning). What is the harm in 
playing out with many toys? It may work, it may not. But IMHO it 
helps to have a broader perspective.

So, in this case, the first question is appropriate and not "improper
analysis".

O.K. that is the question the astronomer asks himself when writing a
proposal for a telescope. If you get time allocated you have your
observations and after reducing your data you come back to your home
institution with tons of data. Out of that data you want to get out
**information** and that is the point where you very often nowadays
get stuck because the amount of data is so big that conventional
methods of data analysis fail. So you think of volume rendering your
data in order to get a feeling for your data cube as a whole.

>	   (3) What is the best method of visual analysis
>	       for this data?

Here I disagree. We are not in the stage yet to have a choice what
method we want to use as simply not much has been developed yet for
astronomical visualisation (and that actually was the reason why I
posted a question concerning that to this Newsgroup). The standard
methods developed for other fields are only partly useful as the big
difference between astronomical data and f.i. remote sensing data is
that most of astronomical data is noise and you have to look very
careful for your information whereas in other disciplines its the
opposite where most of your data **is** information.

So what? Is it avs or exist there different packages ( yes, there is
for instance the karma package under developement at the Australia
Telescope). I would appreciate some comments on that.

The "problem" is that AVS (5.0, 5.01) was built using Sun's ANSI SPARCompiler
C (acc) and the AVS libflow/sim archives (and maybe others) you link your modules
with make reference to this specific ANSI function through the C lib functions
used.  You were no doubt using the bundled K&R cc?

__ansi_fflush lives in an archive called libansi.a which is in the ANSI compiler
tree, i.e. it's not bundled.  Recently we have got permission from Sun to
distribute ansi_fflush.o (much like shared libs) so we can make it
available to those of you (like me) who worry that there's more than an
fflush in there.  Else why else would Sun need such a function? <smiley face>
A simple fflush does, however, seem to do the job.

BTW this seems to be a SunOS 4.1.x phenomena, i.e. Sun's SPARCompiler C
for SunOS 5.x doesn't have an ansi_fflush function.  Of course, it doesn't
have a bundled C compiler either.

Hope all this makes "sense"?

Bill

: -pete-

I've had the same problem.  I created a C program (very short) called FORstub.c.
It is included below,

/* for FORTRAN system library  */
extern void _lib_version() {};
extern void __ansi_fflush() {};
extern void __Fz_div() {};
extern void __pow_di() {};
extern void __pow_zz() {};
extern void __s_stop() {};
extern void __z_abs() {};


I put it in the extra_library place in the makefiles downloaded from the
AVS ftp site (North Carolina).  It seems to resolve a lot of my compile
problems! I do not have a complete understanding but the code appears to 
provide stub functions for the linpack package in the FORTRAN library.

Message-ID: <VTN.94Jul7112745@sienna.chpc.utexas.edu>

To generate an integrated volume+geometry rendering, I'm
using the 3D texture input of the geometry viewer, with
the software renderer (AVS4.0, SGI).

The problem I'm facing is the the volume rendering
appears blocky (uniform float field 40x60x40).

Is there any way to smoothen out the vol rendered
part of the image ?  Increasing the volume resolution
I guess is one way, but this makes the rendering 
unmanageably slow.

According to the programming manual, setting
the FILTER option for texmapping should generate
antialiased, filtered images, but this appears
not to be the case when volume rendering (ie 
3D texture mapping) is being done.

Thanks, 

Vinod.

In answer to queries about confocal data from BioRad, the way I do it,
and this isn't the best way I'm sure, but at least it has low brain
cycles required, is the following:

Get the NetPBM package. This is a superset of the PBMPlus image
conversion package that has been on the net for some time.
This package is FREE, and available by anon ftp. 
One place to look:
ftp.x.org:R5contrib/netpbm-1mar1994.tar.gz 

Its on other sites as well, use archie to find the source nearest you.

In the package is bioradtopgm, which converts a Biorad confocal file into 
a portable graymap (pgm).
There is also zeisstopnm, for those with Zeiss microscopes.

This will allow you to put individual planes each into a pgm file.
These can be read into AVS with the READ_ANY_IMAGE (or in the future,
multiformat read module, when it is released), as a single 2d image.

One can use the glue module to collect individual planes into a 3D field.
Both READ_ANY_IMAGE and glue are at the IAC. multiformat read should be there
soon.

Good luck,
A.J.

I have set up a network that reads in a field, performs various
operations like isosurface and slicer.  I also have a create_geom
with a tube filter; all modules leading into the geometry viewer.
I write the network to the disk.

When I call up the network, the isos and slices show up, but
I loose all the cylinders created with the create_geom
module.  How do I save the network in order to insure the
geometry objects all appear when the network is re-opened?

Thanks to the people who have answered the questioned I have
posed earlier and thanks to those who will (hopefully) answer
future questions.

I'm running AVS on a 720/CRX24Z (hp-ux 9.05) with the VUE environment.
I has seen no difficultly with the 'display image' module.

I have:
		NoHW 0
		VisualType DirectColor

in the .avsrc file.

I'm not sure why the absence of Vue would cause you trouble.
What are the symptoms of your problem?
What is your hpux rev?

Hi netters,

A while back I posted a message asking people about problems
with graphing (in 2D) large amounts of data. Some have indicated that
this is an application that Khoros, AVS, or IDL currently do not 
handle well.

I have now implemented a C++ library that can be used to graph large
amounts of data. I'm currently using it to look at some soil sensor
data. And I'm also looking for different data sets that I can
use to demonstrate its capabilities. In exchange for a large sample data set,
I will provide you either with my library, or even construct the 
application according to your specifications so that you can use it for 
your own visualization. (The objected oriented approach allows me
to contruct a new application in a short time.) If you have problems
constructing visualizations with  2D plots, this would be an
alternative that you can try out. I would also appreciate any pointer
to any data sitting out there, waiting to be visualized.

If you wish, I can try to make the software available via
anonymous ftp. (I would have to find out how, though)

Some information about the C++ library:

-Platform: Unix and X windows, using Xlib and Xt.

-Features:
    Large amounts of data: no restriction on data size
    Overlapping graphs, and multiple windows.
    Linked axes between graphs (scroll one and you scroll the other 
            automatically).
    Point, discrete, and continuous line graphs.
    Fine grain control: controls appearance on the granularity
            of each data point or each line sgement.
    Can handle missing data in line graph.

-Model: Textual data (TData) --> graphical data (GData) --> visual 
Textual data (TData) is supplied by the user, as a sequence of records.
Graphical data is created by mapping each record of TData into
a record of GData. Each GData record contains the following
attributes: location, size, color, pattern, orientation, and shape.
Graphical data is rendered as a visual, currently a bitmap display.

-Programmer's tasks: provide the mapping from TData to GData,
decide which graphs are linked, and act on user interaction.
However, programmer need not worry about internals such as how
to do a scroll or zoom, when to perform the mappings, or how to handle
memory management.

-Efficiency: 
    Does not use virtual memory. Memory buffer for TData. Memory
    and disk buffers for GData. Prefetching for GData and TData.

    Optimized for drawing large number of shapes.

This research was conducted under the supervision of professors
at the University of Wisconsin-Madison, and supported in part by an IBM
fellowship. For further information, please contact:

Set the saturation levels to all zero, then use the edit/ramp button to 
set the brightness to a ramp.

Voila, greyscale.

Module path : avs.ncsc.org:avs_modules/filters/unif2zscat
Ported to   : HP DEC
Description : unif2zscat - uniform 1D to Z-line scatter. This module
              takes an input field, such as a 1D n-vector uniform field,
              and creates a new field with all the same data values, vector
              length, etc., but in addition adds irregular coordinates,
              creating a scatter field. The coordinates added have X=0,
              Y=0, and Z changing as a function of the data index with
              uniform spacing. This module is a simple filter used to test
              the "scatter_ribbon" module, for a well log display. This
              module will work with byte, float, int, double, or short
              data types.

Module path : avs.ncsc.org:avs_modules/mappers/strip_charts
Ported to   : Sun HP DEC Kubota
Description : I got sick of people saying that AVS won't do mutiple strip
              charts, even though we all know "it can't not do it," so I
              whipped up this demo. (It only works with float data, and
              assumes a data range of 0.0 to 256.0, but it does make a
              convincing demo.) The module is a subroutine module that
              takes multiple input signal lines from a float 2D field, and
              creates a line map showing the progression of the signal
              amplitude. The representation is created using AVS
              geometry, and may be sent to the geometry viewer, "tube"
              module, etc. An extent box is drawn around the border of the
              plot area. By using an animated integer controlling a
              moving crop region, the signal can be animated to simulate a
              traditional chart recorder.

Ported to   : Sun HP DEC Kubota
Description : scatter rect - Draw Nested Rectangles from irregular 1D
              (scatter) fields. This module draws 4 variable height
              nested coloured rectangles from scatter input data
              showing 4-vector data at the specified positions. Each
              sample point gets 4 stacked rectangles. The first three are
              various colors, and fourth is a wire frame shell around the
              others. It can be used in place of "scatter dots". The Scale
              dial is simply a size multiplier. The height of each nested
              rectangle is controlled with one of the vector quantities.

Module path : avs.ncsc.org:avs_modules/data_input/READ_TIN
Ported to   : Sun HP DEC
Description : NAME READ_TIN - Reader for Arc/Info Triangulated Region
              Mesh The READ_TIN module accesses external ASCII files
              defining a triangulated irregular network (TIN)
              structure from Arc/Info. This is generally used for a
              surface representation derived from irregulary space
              sample points and breakline features. The TIN data set
              includes topological relationships between points and
              their proximal triangles. Each sample point has an x,y
              coordinate and a surface, or z-value. These points are
              connected by edges to form a set of nonoverlapping
              triangles userd to represent the surface. TIN files are
              also called "irregular triangular mesh" or "irregular
              triangular surface model" in some contexts. "TIN" is the
              name of the ESRI Arc/Info application module that models,
              creates, displays, and exports TIN files. Within the TIN
              application the UNGENERATETIN command with the NET option
              should generate files compatable with this reader module.
              An optional image input port will apply a full colour
              texture map onto the TIN geometry, such that the geometry
              viewer can show the texture overlay on the terrain. The
              second file browser (WorldImageFile) allows a small
              coordinate range correction file to specify the mapping
              between the optional input raster texture image and the TIN
              coordinate system. This module requires AVS 5.01, with
              texture per object support.

Module path : avs.ncsc.org:avs_modules/data_input/read_GOCAD
Ported to   : Sun HP DEC
Description : This is a data import reader module for the GOCAD (ASCII)
              file format. The GOCAD application models, edits, and
              describes 3D geologic structures, containing horizon
              surfaces, faults, and wells. The GOCAD application is
              authored by a group in Nice, France. This module reads the
              contents of one GOCAD file, and converts this to the AVS
              geometry data type, which can be sent to the Geometry Viewer
              for interactive display. Axis specific scaling is allowed
              by using the floating point parameters, supplied with dial
              controls by default. The module ignores all other lines
              from the GOCAD file except for vertices and trianges. It
              looks at the first character of every line. If the the line
              starts with "V", then it reads the id, and the position x, y,
              z. If the line starts with "T", it reads three index numbers
              for which set of verts to tie together as triangles.

              converted into the MOSS files using the "ARCMOSS" utility
              in the data conversion utility subsystem. This module has a

Description : Marker_Pick - Pick, Edit, Create, and Move Markers on
              Images. Allow marker pick identification and display from
              an input marker list and the image viewer system. Takes as
              input an AVS field with a list of coordinates for markers,
              displays them over an image (map) in the image viewer, and
              reacts to mouse picks on these markers, sending the pick
              selection to the output port. Markers are defined by
              geometric polyline vector lists, not ROI pixel masks. You
              can externally control position, shape, size, etc. Any
              marker field sent out on the output port can be read back in to
              the input field port. This way state save and restore are
              possible. New marker lists can be made using the
              "marker_pick" module.

Description : marker_merge - merge roi marker pattern with full colour
              image. This module modifies a full color input image by
              masking it with an ROI byte field. The marker type code in the
              ROI is used to control what color is replaced inside each
              marker area, and optionally a secondary texture image can
              be used as the fill color inside of the marker areas. The ROI
              field is compatable with other ROI field modules (IP Lib).
              This module is designed to work with other marker modules,
              marker_gen, marker_select, marker_draw, marker_pick,
              etc.

              is compatable with any AVS image, and any fully specified
              marker list 1D integer field. The marker list can be
              specified from a stored field, or more often,
              marker_select, or marker_pick modules. This module scan
              converts the marker edge list into a binary bit pattern,
              where the bit pattern at each pixel is either zero for no
              marker present, or the marker shape index. The output is a
              full size scalar byte field, the same size as the input
              image.

Ported to   : Sun HP IBM
Description : The texture mesh module serves two needs. First, the need
              for a robust module for mapping 2D data to quadrilateral
              meshes is served. The input 2D data may be a 2D uniform field,
              in which case the x,y coordinates for the output mesh is
              derived from the extents information (if present) or using
              a mapping from indeces to space if no extents information is
              present. The z values are obtained from the data in the
              field. The second need fulfilled by this module is support
              for texture mapping. Two types are supported. The first,
              called "dynamic" in AVS parlance, is the traditional type
              of texture mapping where the coloring of the surface is
              postponed until rendering time. The second type, called
              "explicit" here will color the vertices of the field based
              upon the image on the second input port, along with the uv
              coordinate ranges specified by the user.

Description : This is not *quite* a new module, rather it is a successor to
              "read_shak" which now becomes obsolete. CRYSTAL is a
              crystal structure viewer for AVS. It accepts files in one of
              several formats - currently SCHAKAL, SHALXL and PDB,
              although I hope that some enterprising person may add more
              readers. The SCHAKAL and SHELXL formats fully support
              generation of complex structures from an assymetric unit
              with space-group symmetry operations which can be typed in
              almost verbatim from the "International Tables". It has
              facilities for replication of unit cells, slicing the
              displayed structure using a miller plane, calculation of
              interatomic distances and variations on the
              ball-and-stick/space-filling display. The
              distribution includes a small number of example datasets,
              though I can supply more on request. This actually comes in 2
              pieces. crystal - an AVS module for displaying crystal

Description : UCD Node Contour creates an array of floating point RGB
              values, one color for each node in an unstructured cell data
              set. This module is a replacement for ucd-contour as
              supplied by AVS Inc. AVS Inc's ucd-contour module turns
              zones of out-of-range data black, rather than clamping it
              to min and max values as the user often prefers. This module
              is intended as a functional equivalent of ucd-contour, but
              which clamps out of range values to min and max colors. This
              allows more detailed coloring of data within the absolute
              range of the entire UCD without turning any of it black. UCD
              Node Contour is used to create a color contour of a UCD
              structure. Its output is passed to ucd-to-geom to produce a
              colored representation of a UCD structure. UCD Node
              Contour associates a color with each node of a UCD
              structure.

Description : The "Mouse Trap IV" module accesses the X-Window of the
              Image Viewer display, and changes the mouse button
              definitions. It intercepts all mouse events, and then
              selectively sends commands on to AVS for action. This
              version ignores all normal image viewer mouse controls,
              and causes special behavior instead. The left button will
              "zoom in" the image, while the right button will "zoom out"
              again, each by a preset amount. It is intended as an AVS
              application developers example, to create custom
              interface controls. This module also shows how to change
              the mouse cursor shape while over viewer window. This is
              intended as a source example for further development work.

              workstation. This module takes in a byte/voxel dataset, a
              colormap, and a transform matrix and renders a volume in a
              window. The difference with this module is that it
              implements a form of gradient shading. For coding
              convenience and speed the light source direction has been
              limited to one of the 26 vectors which pass directly through
              an adjacent voxel. The gradient magnitude is approximated
              as the magnituded difference of voxel under computation
              and the adjacent voxel along the light source vector. This
              magnitude is store in a second byte (per voxel) along with
              the original voxel scalar magnitude byte. This 2 byte per
              voxel field is fed to the CUBIC_POLYPOINT gescape along
              with a table which contains a lighting model applied to the
              original colormap supplied to the model. This lighting
              model is driven by ambient, diffuse, and specular
              weighting and theta/phi light source angles supplied as
              input parameters.

Updated Module at IAC - Create_MPEG

Name        : tubeness        Version      : 2.000     Mod Number : 1791
Author      : Wes Bethel, Lawrence Berkeley Laboratory
Submitted   : 04/21/94        Last Updated : 07/15/94  Language   : C
Module path : avs.ncsc.org:avs_modules/filters/tubeness
Ported to   : Sun HP DEC IBM
Description : The tube module transforms an AVS geometry, replacing a set
              of disjoint lines with "tubes." The tubes are polygonal
              approximations to cylinders. The number of sides used to
              represent the cylinder is under user control. Version 2
              update - those line segments which are "degenerate" will be
              cause a sphere of radius "radius scale" to be generated
              rather than a flat cylinder.

Name        : read_F3D        Version      : 5.000     Mod Number : 1537
Author      : Michael Rangitsch
Submitted   : 10/03/92        Last Updated : 07/15/94  Language   : C
Module path : avs.ncsc.org:avs_modules/data_input/read_F3D
Ported to   : Sun HP DEC
Description : This module reads an ascii formatted multiblock FLOW3D
              solution file (from Harwell FLOW3D version 3) and stores
              the cfd data as a ucd data set. The dummy nodes stored at the
              edges of each computational block are removed by the
              module. The n-vector data at each computational cell is
              stored as cell data, to use most of the ucd modules, this must
              be converted to nodal data. The cells of the ucd structure
              are all hexahedra. See the sample data directory on the
              International AVS Center's anonymous ftp site for two
              sample data sets to read with this module. Version 2.000 has
              several enhancements and debugging features added.
              Version 3.000 adds geometry representation of 2
              dimensional patches. There are 7 types of 2D patches
              defined by FLOW3D. This code probably doesn't work for 3d
              patches. Version 4.0 handles unanticipated data sets, and
              processes cylindrical data sets and single block data
              sets, as well as several other enhancements. Version 5.0
              handles unformatted as well as formatted data.

Name        : read_netcdf     Version      : 2.000     Mod Number : 1564
Author      : Wright, E.L., U.S Geological Survey
Submitted   : 01/22/93        Last Updated : 07/15/94  Language   : C
Module path : avs.ncsc.org:avs_modules/data_input/read_netcdf
Ported to   : Sun DEC
Description : This module reads data from netCDF files into uniform or
              rectilinear AVS fields. The data variables must be of
              dimension 8 or less. Variables that are one-dimensional
              and have the same name as a dimension name are assumed to be
              coordinate variables. Coordinate variables, if present,
              define the coordinate values along each axis of the data
              space. A maximum of 8 data variables that are NOT coordinate
              variables may be present.

Name        : city_scape      Version      : 3.000     Mod Number : 1185
Author      : Ian Curington, Advanced Visual Systems
Submitted   : 05/04/92        Last Updated : 07/15/94  Language   : C
Module path : avs.ncsc.org:avs_modules/mappers/city_scape
Ported to   : Sun HP IBM Kubota
Description : The city scape module converts a two-dimensional floating
              point field into group of 3D blocks, represented as a
              GEOM-format mesh. Each element of the field is mapped to a
              "building". The height of each block above each point is
              proportional to the scalar value of the field. This is my
              attempt at "Business Graphics", for a multi-dimensional
              telecommunications statistics data application, except
              in interactive 3D. Version 2 is a substantial upgrage from
              version 1 at the IAC. This module provides 3D block diagram,
              with averaged statistics on side shadow panels, and
              annotation. A transparent theshold sheet is superimposed
              on city. Blocks can be picked for interogation of cell
              number. parts may be turned on or off for clarity. Two scalar
              fields can be displayed, one contolling height, the other
              color, with two independent side stacked side bar
              statistics. Version 3 update draws the top face of picked
              block in white hi-lite, adds extra edit list for pick, no
              normals, new text input for edge labels, added string
              typeins for edge labels, and other fixes.

Name        : Create_MPEG     Version      : 2.000     Mod Number : 1789
Author      : Alex Knowles, The University of Manchester
Submitted   : 04/21/94        Last Updated : 07/15/94  Language   : C
Module path : avs.ncsc.org:avs_modules/data_output/Create_MPEG
Ported to   : Sun HP DEC IBM
Description : Create MPEG is a subroutine module which will create MPEG
              movies from a series of AVS images. It uses Andy Hung's
              'MPEG' which is available by anonymous ftp from Stanford.
              Because of the way MPEG movies are encoded by 'MPEG', many
              temporary files need to be stored, bear this in mind when
              choosing which directory to make your movie in. Version 2
              fixes bugs.

This sounds like a good candidate for user error, but I, the user, cannot
determine the error.  I am using trigger_int to synchronize output to 
write_image.  The network (shown below) is used in conjunction with the
animator to save an animation as a series of image files.  It appears to
work on the surface, however, upon examination of the images I find that
every other image is repeated.  For example, image 2 is the same as image 1.
Image 4 is the same as image 3 and so on.  Has anyone encountered this
problem?  Any fixes?


Thanks,

I have a network that generates a 2D uniform field and then converts the
field to a mesh geometry.  It generates several of these fields that 
represent motion of a wave in 2D.  The field_to_mesh module displaces the
mesh in the 3rd dimension.  I would like to map a texture onto this geometry
dynamically.  I can currently map the image onto a "static" geometry.  However,
as soon as the wave is set in motion (new fields are generated) the texture
disappears.  Is there a module that will allow me to keep the same image
mapped to the geometry ( same uv mapping) as the geometry deforms?  Any
help would be appreciated.

Thanks,

  -Tim

Hi netters,

We have made a comparison of visualization techniques and packages. The
report is placed in WWW: http://www.sara.nl/Consumer.Report/Report.html.
It consists of a general part with descriptions of AVS, IRIS Explorer,
Data Explorer (DX) and Data Visualizer. The other part contains a study
about how these visualization packages have been used in visualizing
plasmaphysical processes.

I hope it helps in deciding to choose which package you can use best
in your research.

Greetings, Rik Leenders

On invocation of avs i get 

Could not load program avs 
Could not load library libgl.a[shr.o]
Error was: No such file or directory

The library libgl.a is neither part of the AVS distribution

There is only libgl_stubs.a in $AVS_PATH/lib.
How is this supposed to work?

If you have a Convex nearby, you can use them as remote modules.  If you'd
like to discuss the possibility of porting them to other architectures, please
drop me a line and we can discuss it.  Regards...

I need to animate a scene containing four rather complicated
geometries, and the manual isn't very helpful. The geometries were not
created in such a way that it would be convenient for me to make one
of each for each frame (not to mention the size constraints), so I
thought I might try making a network to output each frame to a tiff
file instead. I already have a tiff module, and what I need to do is
fairly clear:

1. produce a series of .scr files.
2. convert each .scr file to a tiff image.

Does anyone have any experience with this? How should I go about
producing the .scr files for each frame? (say I want to rotate the 4
geometries about a central axis). And how should I build a network
that will do this for me when I am not around? Is there a manual
section I should read?

Thanks.

This may well be an FAQ (apologies) *BUT* has anyone out there attempted (ie written

for pulling data out of an ORACLE database to be used in AVS ???

Any info will be greatly appreciated.

AVS Inc. is working on a new product to interface AVS to Oracle.  
This product, called AVS/SQL, is a toolkit that provides a fully
functional collection of AVS5 modules that interface to Oracle.
As AVS5 modules, they let a user directly connect, query and extract
data from either a local or a remote wide area networked database
server.

AVS/SQL is currently in beta test with several AVS customers. If
anyone is interested in participating in this beta program, please
contact me directly.

    I don't really understand your problem. Are these pictures images ?
    If they are images, you may write a module to normalize them.
    Just a few lines of C codes. I wrote one for my own purpose.

    I solved the same problem today :)
    If you are an AVS user, you may mail to support@avs.com.
    Ask Mr. Larry Gelberg. He will answer your problem by
    sending you the source codes.

I have been trying to compile the write_pict module for avs.
I grabbed the libsdsc.a and libim.a from sdsc - but it appears that these
are the old coff formats - not ELF - for the SGI Indigo   2 machine running
IRIX 5.2.

The source for the libsdsc does not appear to be in the tar/cpio files I
retrieved from the sdsc machine either.

Does anyone have these or an sgi compiled copy of this lib?

Or does anyone have a different write_pict module I could get?

Hi netters,

Last week I anounced the availability of our report on 'Comparison of
Visualization Techniques and Packages'. Because many people asked for
a PostScript version I made one which can be obtained via (anonymous) ftp:
ftp://onyx.sara.nl/. It is called Report.ps(.Z). The WWW version of the
report (http://www.sara.nl/Consumer.Report/Report.html) now also contains
the possibility to ftp the document.

Greetings, Rik


P.S. See you all next week in Orlando.

The Liverpool University Image Database Group is constructing a 
report (which will be available as a Gopher resouce) titled: 

	"Image Database Systems for Unix Environments".

Although primarily interested in hardware and software (we hope to 
cover both working and research systems), we wish to contact potential 
and current users to enhance our understanding of the image database 
requirement.  Although our brief is to cover the Unix environment - we 
hope to look at anything that might be out there.

Our aim is to generate a "wish list" which might serve as a pointer for 
research, as well as a "which guide" to what is currently available.
Consequently, we are not too concerned about what might be an "image
database" - we are interested in what the community thinks is one and
the facilities it does or should provide.

Given these aims; we seek users, developers of databases, and systems and
research people who are prepared to share with us their expertise. In
return we will ensure they get an early copy of the report.  If you can
help us, please respond to these questions.

1. do you wish to be registered to receive a copy of the report; if yes
   please provide your full Name and Postal Address.

2. how do you define an image database ?  Do you consider yourself an 
   image database end-user or potential end-user, a database developer,
   or an image database systems person ?

3. what is your experience of image databases ? are you a regular user ?
   how would you rate your a) practical knowledge, b) knowledge of
   theoretical issues ?

4. what image database systems do you know of ? what hard/software 
   requirements do they have ?  What are your opinions of them ?

5. who do you reckon are the experts in the field of Image Database ?

6. assuming no constraints - what would your ideal system provide by way
   of facilities ?  How would you expect to use it ?

7. what features would you expect to see in a minimal image database
   system ?

If you merely "reply" to this posting it should get to us.  If you can
include details of the newsgroup on which you found the posting we would 
consider that a bonus. Alternatively, if you email us (imdb@csc.liv.ac.uk)
please include the word "posting" in the subject field of the header.

In anticipation - Many thanks for your help.

=========================================================================

If absolutely pressed OUR definition of "image database" would include:

	image, digital photograph, and picture archives, video clip databases, 
	cad/cae/cal databases, fine art image libraries, art photographs,
	medical image libraries including thermal imaging pix etc,
	geographical information systems (gis) in their  widest sense - 
	including remote sensor imagery, visualisation databases, digital 
	imagery of manuscripts, animation libraries, etc.

At present, every time I bring in new set of data into a module, I am labeling 
it and saving it as a different network to solve the problem I have.

My question is, is there any way to store appropriate lable for each data set 
within a single network so that the new label is automatically added to
the display? Any solution?

I have a large collection of 3-D vertices that I want
to convert into geometry format. However, the data is
random, just vertices, no connection information.  What I need
is a routine to place these vertices into a geometry format
that outputs a 3-D mesh of the data.

Does anyone know of modules to do this. What about something similar?

Hi all!

I defined a field as:

CompDim=4 (1,1,1,187)
PhysDim=3

It's a vector field (3D). 

The problem is that the Physical Coordinates are written in the field as 
@(0,0,0)
using the ADIA or the ASCII (manual) description. This does not happen if
I define it as
CompDim=3 (1,1,187)
PhysDIm=3

Did anybody get the same problem? I know that at least for now it could be
logical to define it as
CompDim=2
but if I do it there is no way to use Hedgehog to show the vectors (now I
use this system:

                  ReadField
                      |
                  Time Sampler
                      |
                  Hedgehog
                      |
                  Geometry Viewer   )

Since I started using AVS few weeks ago, any help will be REALLY appreciate

Scott,

one possibility should be:
     
  1. read in your data as a 1-D field of type irregular (the data
     values are arbitrary, the coordinate information is the coordinates
     of your vertices)
     
  2. convert the field to unstructured cell data with the module
     scatter to ucd
     
  3. convert the ucd with ucd to geometry

Good luck.

Hello there

I'm a novice of AVS. This my problem:

I have a text file which contains values of a function F(x,y) on a regular
lattice. Each rows contains the triple

row	col	value

How can I plot this 3d function (with no hidden lines) in a wire-frame fashion?
Maybe, is this a FAQ?

Thanx

     Modular Visualisation Environments (MVEs) - Now and the Future
                    Special Interest Group Meeting
            SIGGRAPH '94 (info from siggraph94@siggraph.org)
                        Orlando, Florida

                               oOo

                      Tuesday, July 26, 1994

                               oOo

This is a final reminder that we will be holding an informal special
interest group meeting on Modular Visualisation Environments (MVEs -
examples include Explorer, Data Explorer, apE, Khoros and AVS), trying
to talk about what is available now, and what people would like to see
happening in the future.

It is hoped that this will give a chance for people from all fields to
speak in GENERAL terms (there are other SIGs for specific packages),
and discuss the many issues. Present will be developers of such
systems, users, and interested parties - in short, if you want to
come along, please feel free to turn up !

To summarise the announcement (which is posted in full below), we aim
to have some short presentations, followed by general discussion which
will hopefully be as informal as possible, but whose exact format will
depend somewhat on how many people attend. Finally, those interested
can head to the pub !

Those giving short talks include people representing AVS, Explorer and
Data Explorer, a developer involved in research on a spray rendering
MVE project, and at least one `power user'.  [Khoros developers are
unable to attend due to time constraints, but I am still looking for
someone who can talk on K2 - in addition, apE people are welcome].

Look forward to seeing you there,
	-Gordon.

P.S. Many thanks to Len Zaifman for aiding in organisation.

P.S. To reiterate, this is not AIMED to solely be an advertising forum
for certain packages, nor will it consist of marketing people getting
involved in TOO heated argument with one another :-) However, if you
come along, I guess you can chase up certain people afterwards, and
pick up more info.


-----------------
--- OVERVIEW ----
-----------------

This is an informal `panel-type' session to try and talk in general
terms about the current MVEs (such as AVS, Explorer, apE, Data
Explorer, Khoros, etc.), their uses, limitations and benefits, and the
future of such systems and others. In attendance will be people
representing many of the main suppliers and developers of such systems,
as well as users, potential users, and interested parties !  Everyone
with an interest is welcome (and encouraged)  to come along.

The `agenda' is very rough and flexible, as I feel that it is best if
the thing stays as informal as possible. If there are any comments you
have on things that you'd like to see, then please feel free to mail
me, or just ask at the time (for example, if any users feel they have
something that they would like to show that highlights a particular
issue ?) - I've got a classrom-type place booked (as opposed to a
boardroom or lecture theatre), so this should make it much easier to
keep things informal.

I may try and keep some sort of record of what goes on - if the
thing is successful ! - so that those who can't attend get a feel for
what happened.

Thanks to Brian Blau for organising the room so quickly, and Len
Zaifman, George McGregor and many others for offering to help out.
--
INFORMAL AGENDA
---------------

1. Developers/Users of MVEs (Past, Present and Future)
--
	* Brief introduction of some of the development people (on the
		`panel')

	* The relevant people *briefly* talk about their company's
	  product, new features, futures etc. ( this is useful in
	  letting users/attendees know what is available, but I don't
	  really want this to drag on - I would imagine each of the
	  companies present may want to leave some glossies etc. lying
	  around)

	* Each of the developer-y people might want to briefly state
	  what they see of as the future of MVEs (in general terms)

2. Informal Panel/Discussion 
--
	* Summary of the things which interest the audience, and their
	  backgrounds

	* General questions and discussion between all those present on
	  the present and future of such systems.  I hope that this bit
	  should take up the biggest proportion of the time, and that
	  the things discussed are not fixed. Some ideas, from myself and
	  others, could be :
		- what users want
		- what users can and can't do
		- what users like/dislike/use/don't use
		- typical problems
		- the data-flow model, and developments
			(e.g. AVS/Express, Explorer/ImageVision, Khoros..etc?)
		- how to make things portable
		- how to affect the future development 
		- advantages and limitations of MVEs
		- input & output to systems - connection to other apps
		- validation, verification, comparison, testing...
		- segmentation etc...
		- Use in medical and other safety crit. systems
		- futures ?
		- platform availability
		- `proper' parallel machine support (not just distributed
			computing, in other words :-)
		- system integration ?
		- open systems/cost of development ?

3. `Who's Best Discussion' Between Developers 
--
	* ONLY if there's time ;-}

4. Pub (optional) 
--
	If there is a local drinking establishment nearby, people could
	perhaps decant to this if they wish to continue `talking' :-)
--

Note that I don't think concentrating on individual products TOO much
will be useful, as there are SIGs for the specific products at this
SIGGRAPH and Vis' 94 (AVS (Wed. 4-6) and Explorer (Thur.2-4) at the
former, and Data Explorer at the latter).

I hope this meet will prove useful and interesting to users and
developers alike.

Comments etc to gordonc@epcc.ed.ac.uk.

See you there !

Has anyone ever tried to read multiblock grid files using read_plot3d?
I can't get the grid number parameter to be anything but 1.  When I try
to read with grid number set to 1, I get an error telling me that this
value is unreasonable.

Thanks in advance,

	         	 Announcement
       The Journal of Imaging Systems and Technology

This journal has been published by John Wiley & Sons, Inc. since 1989.
Earlier this year, its editorial board and its name were changed.
The new editors are Z. H. Cho (University of California, Irvine) and
L. A. Shepp (Bell Laboratories).

This interdisciplinary quarterly journal offers comprehensive coverage
of imaging science and technology.  Papers are drawn from a range of
areas, such as physics, chemistry, biomedical sciences and engineering,
radiology, geoscience, astronomy, computer science, mathematics, material
science, oceanography, etc.  Articles stress research and techniques
that are common to the imaging science in these fields.  The journal
therefore provides a single source for current information pertinent to
scientists, engineers and specialists working in the area of imaging
science and technology, as well as a forum for the development of new
technology.

All the submitted papers are reviewed by at least two referees. The editors
try to maintain very high standards and papers are judged primarily on the
ideas they contain, novelty, and relevance. All submitted papers should be
sent to:

   Professor Z. H. Cho
   Department of Radiology
   University of California
   Irvine, CA 92717

The read_plot3d module supplied with AVS will only read a single
block plot3d file.  Since the module produces a field, that is the
only type of plot3d file you can read with it.  I have written a 
primative (read it dosn't work yet) module to read multiblock 
plot3d files and load them into a UCD structure.  I didn't finish
it because I was unclear how to use the IBLANK information to 
properly 'weld' the edges of the multiblock domain.  

Maybe I'll have time to get back to it someday...

You might try the MOSS_Polygons module recently placed at the
IAC ftp site.

Use Arc/Info to generate an export ASCII coverage in MOSS format,
then use this module to import it as an AVS geometry.

Hi,

We have a series of images that we view using the Geometry Viewer.
They represent various atoms moving around inside a structure made 
up of other atoms.

We would like to animate this sequence of images and view the actual
motion.

It seems like I should be able to do this using the Action submenu
in the Geometry Viewer, but I just cannot get it to work.

Could someone send me the sequence of step necessary to take this sequence
of images from the Geometry Viewer window into a flip book animation.

Thanks,

John Boccio

A simple way is to connect the Geometry Viewer module's (in the network editor)
output port to the input port of the Image Viewer Module. Then use the "Store
Frames" option in the "Action" menu in the Image viewer. 

The Action menu under the Geometry viewer is for loading sequences of 
Geometries, as opposed to sequences of images.

The Image Viewer can then write the sequence images to disk. There's a 
create_mpeg module on the IAC ftp site that can write image sequences to 
mpeg animation files, but I haven't used it (probably won't work on a
64-bit machine, I suspect)
