Hallo,

I have an animation of a fluid and I would like to use some effects
to get a more ralistic 3D animation.
One of the effects is shadow.
How is it possible (if it is !) to project shadowns of the objects on another
objects.

One simple case is : a shadow of a sphere on a plane. 
The sphere can flay over the plane. Is  it possible with AVS to progect 
the shadow of the sphere on the plane ?


Any help will be appreciated,
 - Ion Barosan

Dear fellow netters,

	we are looking for pointers to literature on visualization of tensors. 
Especially we are interested in the visualization of stress tensors as results 
of FEA (e.g. mining, tunnel construction...) Beside this we are also
interested in the computation of stress trajectories.

	We have the proceedings of Visualization '91-'93 but would be happy to 
receive any further pointers.

Thanks in advance

Georg

I am working with some CFD researchers and want to show them what AVS
can do for them as a CFD postprocessor.  Unfortunately, I cannot find 
a module that will read in StarCD data.  I don't want to go through the 
effort of learning the data format and writing a custom module for this 
demo, so I was wondering if anybody on the net has already done this.

Thanks in advance,

Hi,

I would like to know what others do when they want to plot
medium sized files of scatter data in an AVS geometry 
viewer.  The data is much like the data for a contour file.

I have an ascii file with about 14,000 points in it.  The 
format is "X Y value", with X and Y as floats, and the value 
as an integer.

For other reasons I would like to plot this in a geometry
viewer.

I was going to use field to mesh, but it expects a 2D input.
My data is 1D irregular, and that won't work with the field
to mesh.

I have tried using scatter to UCD and UCD to geom, modules,
but it swaps my SGI indigo to death ( and I have    64 megs
of ram).  Is the UCD types rather inefficient? Or am I doing
something wrong?

Can anyone think of a better way to do this?  Perhaps I am just
using the wrong tool.  I can display it in Spyglass ($199.00)
in about 2 minutes.

thanks!

email responses please.

Ditto here.  I'm doing the same sort of thing, flow visualization and
temperature distribution specificly for a PC board.
Other than the standard AVS features where can I find advanced modules
special for this kind of visualization.  Data format is not an issue
in my case. However, this problem is 3-D and any module must accept 
3-D data, i.e. x,y,z,() .  Is there an FTP site?  I'm very new to
this software and the CE dept. keeps all the manuals and doc. hidden.
I Guess since they actually paid for the license.  Any help would 
be appreciated.

Quite a few people have emailed me about this capability of IDL, which
I was not aware before my posting. Thanks to all who replied.

The application I have in mind is to explore a few large data files
by interactively scrolling and zooming their graphs. The combined sizes
of the files are greater than the amount of main memory. What
I want to do is to say, "plot", "zoom", or "scroll", and watch the
results appear quickly. But it seems that I have only 2 choices now:

1) Write my own program to do read data a bit at a time, effectively
doing my own memory management

2) Rely on the operating system's own virtual memory, which can be very slow.

In my previous posting I hinted at database memory managment because
a lot of research has been directed to eliminating 1) and 2) above.
Databases circumvent the operating system's own memory management
policies and implement their own policies for database queries.
In effect, I was asking if there is already something out there that
will try to do the same for me, except that my application is 
"plot", "scroll", and "zoom".

take the 1d, 3space 0vector data and give it to "scatter dots"
which makes spheres.  a long time ago, scatter dots required
scalar data, which it used to compute a sphere radius.  a
module at IAC called "new scatter dots" doesn't require
any data, just a spatial location, and will digest
N-d, 3 space, 0- or 1-vector data.

if you want to get a surface that goes through all the points,
check out "scat2d" or "bivar" from IAC.  these modules take scattered
data, and will output a 2d, 3space data which you can give to
field to mesh.

I am trying to use the graph viewer via cli language.
With AVScommand function it is possible to send to the kernel cli commands.
I have two graph's windows in which I display two plots (XY-plots).
The input of the graph viewer is an ascii file.
What I want is to be able to change the input file and to display the plots
in differents windows.
But the graph viewer will display the current plot in the current activated window
(that which has a red frame).
There is no  cli command, which deal with the selection of a graph's window.
I can do it with the mouse, but I want to automate the procedure.
There is a way in AVS to change te current graph window of I have to use X11 ?

Any help will be appreciated,

 - Ion Barosan.

Hello,

we would need a callable function to read an AVS field file into the 
AVSfield data structure. This is just the functionality of the module
"read field", but I didn't find such call in the Developers Guide.
(There is a function called AVSfield_read in the libflow_c library, but this
one is not documented)

If anybody knows about a function which has this functionality, please let
us know.

Thank you,

Harald

Hi Dave,

We've got an AVS_README and a FAQ file at avs.ncsc.org:/avs_readme
They're called AVS_README and FAQ, respectively.

Also, we've got all newsgroup postings for about 2 years stored at
avs.ncsc.org:/newsgroups/comp.graphics.avs/*.

In terms of your texture map question, just go to "Edit Texture" in the
geometry viewer panel, and you can read in an image to be mapped onto the
current object using a browser that comes up.  Depending on your platform,
you may have to use software rendering though, which slows it down a bit.

Take care,

-Steve

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.   Also, the AVS '94 Program Committee 
(avs94pc@avsusers.ncsc.org) is seeking submissions for the
AVS '94 Video Review and AVS '94 Poster session.

Dear AVS User,

The IAC has been soliciting submissions for the Spring 1994 issue
of AVS Network News, which is to hit the streets on May 2, 1994,
in conjunction with the AVS '94 Conference in Boston.

This will be a special "Image Gallery" edition of AVS Network News, 
that will contain only one or two short articles, by the IAC.  The
rest of the magazine will be devoted to FULL COLOR images submitted
by the AVS user community.

All AVS users are invited to submit 1-5 images for this issue.  
Depending on the number of submissions, the IAC may not be able 
to print all or any of an individual's submissions.

I currently have you listed as a definite or potential submitter
for this issue.  If you are one of the folks who has already gotten
your images to me, thanks very much for your contribution.
Otherwise, please get back to me at your convenience to let me know
whether you're still planning on getting a submission in.  

Spring '94 Net News submissions are due Monday 3/7/94 at 12 Noon EST.
                                        ----------------------------

   How to submit your images
   -------------------------
   1)  Create your 1-5 image(s) in AVS .x format.

       To help us keep organized on this end, please name
       your images using the format "FirstName_LastName.Number.x".
       So for example if I was submitting 3 images, I would name
       them Steve_Thorpe.1.x, Steve_Thorpe.2.x, and Steve_Thorpe.3.x.

   2)  Create a short ASCII file with a title, description, and
       credits for each image submitted.  

       An image title should be something short, ie "Intergalactic 
       Stellar Gas Cloud").

       Image descriptions should be no more than 40 words for each
       image.

       The credits for each image should list who
       created it and affiliation, also if applicable 
       the source of the data.

       Name this image description file using a similar style as 
       with the image names.  For example, the ASCII description
       file that I would submit with my three images would be called 
       Steve_Thorpe.txt.
	
   3)  Submit the files to the IAC using anonymous ftp.  For example,
       to submit my images I would do the following:

       ftp avs.ncsc.org             (otherwise known as 128.109.178.23)
       cd SUBMIT
       mkdir Steve_Thorpe_Images    (substitute in your name)
       cd Steve_Thorpe_Images       (substitute in your name)
       ascii
       put Steve_Thorpe.txt
       binary
       put Steve_Thorpe.1.x         (substitute in your name)
       put Steve_Thorpe.2.x         (substitute in your name)
       put Steve_Thorpe.3.x         (substitute in your name)
       quit

   4)  Print out a copy of the "AVS Network News Permission to Use 
       Images Form" (included at the end of this message), fill it out
       and FAX the complete form to Steve Thorpe at 919-248-1101.

Please feel free to give me a call at (919) 248-1161
if you have any questions or thoughts about AVS Network News.

Thank you very much for your interest in contributing.  Your work
can make a very valuable contribution to the Scientific Visualization 
community worldwide. 

And also, please remember that Spring '94 Net News submissions 
are due Monday 3/7/94 at 12 Noon EST.

Hi,

We recently got a Action Media II capture board for some mutlimedia ps/2's. 
They give you a sample player for avs files for windows along with some static 
images and a avs video with audio. I wanted to find out more about the whole 
thing and was wondering if there was a ftp site with sample avs videos 
(preferably with audio?). I also would like to get some papers on the whole 
area  - like the avs file format, technical spec. etc.

Also is there any good shareware avs players/editors around? I would also be 
interested in commercial versions so we can start making use of this video 
capture board. Any help in the whole area would be appreciated (pointers to 
ftp sites with a FAQ for this newsgroup?).

p.s. I also would like a program for windows to use the Action Media II 
capture board so we could record from a vidoe player in windows - I have a 
funny feeling I might have to go to IBM for this though  - however if you have 
heard of one please let me know.
A whole integrated recorder/player/editor would be ideal if one exists.

Hoping you can help me..
(Iknow I ask a lot)

Justin.

        You might try putting your data into a UCD.  You will have to
        partition your data space into 3-D cells ( hexahedrons,tetrahedrons,
        pyramids, prisms) such that none of the nonexistent data points
        is included in a cell. Note that it must be a partition---no
        overlap is allowed.  The ucd iso module should then do the right thing.

        By the way, the problem you describe is rather common with the
        AVSfield data type and one of the reasons why the UCD type is needed.
ny time that the domain of definition of the function (the points
        at which functional values occur) is topologically "complex" it
        cannot be represented well with an AVSfield.  AVSfields assume that
        the domain of definition is 2N-fold connected (where N is the
        dimensionality of the space) and that linear interpolation can be done
        between neighboring points.  To make this more concrete, AVS fields
        in 3D assume that there are 6 neighbor points to point(i,j,k)
        {point(i,j,k+1),point(i,j,k-1), . . . point(i+1,j,k),point(i-1,j,k)}
        It also assumes this same neighbor relation for functional values
        and assumes that linear interpolation can generate the values
        between two points (e.g. data(i,j,k) and data(i,j,k+1)).
        Your functions do not fit this assumption.  As you pointed out some
        other packages take care of topological problems like yours by
        allowing a complex data domain to be "gridded over" by a nice 2N-fold
        grid where "illegal" values are used to indicate "holes".
        This can be a problem since it is conceivable that any value you
        may choose to be illegal may exist in some data sets and it can
        also be wasteful of storage since the grid must be the bounding box
        of the data set.  In AVS the use of UCDs to model complex topologies
        is the preferred method.

Subject: Missing data, or data with holes
Status: OR

News Group message:
 I have used to following to visualize data with holes in AVS:
  1. Set missing values to something well out of range of actual data
  2. Use some form of field reader
  3. use field to UCD
  4. use ucd threshold to throw out all cells with out of range values
  5. Then use ucd iso, ucd contour, ucd slice, etc.
    -- producing pictures with holes.
  Note, field to ucd needs 3D fields.

 Sincerely,
 Ian

I am searching for a software tool/solution to allow screen
grab of mixed windows from an AVS session.

All the tools I have tried so far (xwd, xv, etc.) will
grab ONE window of any visual type, or an arbitrary
region of the screen, using a rubber-band region, as long as
ALL the windows inside the region have the same visual type.

I want to grab an arbitrary region of the screen that contains both
8-bit pseudo color visual windows, like Motif window boarders and
AVS user interfaces, along with 24-bit direct color
shaded imagery from the Geometry viewer. I want the result
to be in 24-bit resolution. I can start AVS in pseudo color mode
and grab 8-bit regions, but then I don't get the best Geometry viewer
displays.

Does anyone know of a tool or method for achieving my high-quality
screen grab? Any system may be relevant, I happen to use an HP-700.

Answers to ianc@avsuk.com, please.

Does anyone know how to designate an input port on a homemade module as being 
able to receive more than one connection?  I assume it's possible, since the 
image viewer can receive more than one input, and the connection number is 
passed as a parameter to the AVSinput_changed() function.  The information
doesn't seem to be anywhere in the manuals.  So, 1) is it actually possible to
do this, 2) is the capability there for use in a later version, or 3) is it 
there just to tease us 8^) ?

Any help would be greatly appreciated, of course.

Thanks,

Mark

To set the center of object, I didn't have any luck with the CLI commands
"geom_get_center" and/or "geom_set_center" oddly enough.  I had to use a
sequence of CLI commands to mimic the "center" button on the "geometry
viewer" panel.  If anyone has a better approach, please let me know.

  i) get current object (OBJ)
     "geom_get_cur_obj_name"

 ii) get extents of OBJ
     "geom_get_extents -object OBJ"

iii) extents are returned in the following order:
     xmin xmax ymin ymax zmin zmax

 iv) set center of OBJ (or top object) according to extent info:
     "geom_set_center -object OBJ (xmin+xmax)/2 (ymin+ymax)/2 (zmin+zmax)/2"

Try this out.  It may not be the prettiest solution, but I know it works.
It works great to set the center of the top object according to the center
of a subobject.  Good Luck!

Hello, World,

I have a question regarding the transformation of a 3D irregular
field into a 3D uniform field.

The data of the irregular field locate on multiple oblique slices
which may intersect with each other.  I'm looking for a module which
can derive an uniform field from this irregular field -- each voxel in
the uniform field comes from the interpolation of near data in the 
irregular field.

The module "arbitrary slicer" is able to generate a 2D geom mesh from
a 3D irregular field by using trilinear interpolation.  I'm thinking
that maybe I can use this module to generate multiple parallel 2D geom
meshes, and then gather them into an uniform field.  The question is 
how to tap out the 2D geom mesh and convert it into a 2D image?

Any suggestion is appreciated.  Please reply by email.  I'll summarize
the answers to this news group.

Hi,

Configuration:

  AVS 5.0
  Output of 'uname -a':  SunOS ux6 4.1.2 1 sun4m

  What is the best way to pass a UCD structure from an input port to an
output port, while modifying only select portions of it (i.e. node data
or positions)?  I would like to leave the original structure intact 
aside from modifications I choose to make.
  At the moment, the only way I see to do this is to call a load of 
functions to get a little piece of the structure and then write it
to the output strucuture, and do this for each piece (labels, units,
components, active node, etc.)  Is there any easier way to do this?

Any help will be appreciated.

Thanks,
Kevin

It seems to me that there was a posting earlier about an xdr bug

email it to me. I checked our older articles, but it must have expired.

If you know something about the bug, and it wasn't posted, could you

Hi, can anyone tell me to correct procedure how to turn a geometry into
a image that I can later print or transformed?

I have this geometry or object I have manipulated under GEOMETRY VIEWER
and saved it and later I go to NETWORK EDITOR which I build

     read geometry
         ||
     geometry viewer
         ||
     write image(??)//image to postscript

But the geometry window does not have anything, probably my geomerty not
in viewport. Or I should read in .scr instead of .geom? What should I
use for output port for image output?

Any help will be appreciated/

I remember I saw something like geom to norm which will not show the ploygons

Is there any clean way to do this in avs?  And are there any
avs function calls which support  writing text to window - other

  The UCD library API does not provide an easy way to do this.
  If you need to create a fresh copy, then you need to call
  UCDstructure_alloc, and populate it a piece at a time.
  The /usr/avs/examples/ucd*.c show this technique.
  However, if your network will allow in-place operators,
  where you pass the input port pointer to the output directly,
  then you can just modify bits of the structure without
  creating a copy, saving compute cycles, memory, and lines of code!
  How to do this, you might ask?
  Take a look at an article in the latest AVS Network News
  by Peter Yerbergh of Intera.
  The AVS5 system allows you to 

    1) put a MODIFY_IN flag on an input port.
    2) turn on the ReadOnlySharedMemory 0 flag in your .avsrc
    3) pass the pointer through
    4) add special treatment in a destroy process to
       null the pointer
    5) modify the UCD inplace.

  Look at the module "field_mux", in the IAC ftp site
  as an example of this.

  Regards,
    Ian

Mark,

Not sure if any of these will directly solve your problem, but
they may help.  Especially interesting is Ian Curington's
table_editor mod (the third one listed).

Name        : Edit_File       Version      : 1.000     Mod Number : 1720

Description : The Edit String module puts up a LONG dialog box, allows
              typing of any string, then with either "OK" or "CANCEL"
              controls, will output this string to the output port of the
              module. The next time the "Edit" button is pushed, the
              dialog box reappears, with the old string, which can be
              edited. This module is for long expressions, lists of ints,
              etc, where the normal string type_in widget is too small.
              The dialog box comes up with nicer colours than the default
              grey.

Module path : avs.ncsc.org:avs_modules/filters/table_editor
Ported to   : Sun HP
Description : Like a mini-spreadsheet application, this module
              presents a segment of a 2D array and allows interactive
              editng of the field values. Takes an optional input field,
              displays the contents as a 2D array table of button cells.
              Each cell or group of cells may be selected (high-lighted)
              and new values entered. The modified field is then sent to
              the output port. Values can be replaced, added,
              multiplied, or divided into existing field values. The
              code shows how to create a page layout from within the module
              code. With no input port, this module can be used to
              synthesize new fields. If the input field is multi-vector,
              each vector can be selected from a choice list, and values
              can be edited in each channel, while synthetic data can only
              be created in scalar mode.

Hope these help.

The way around it is 

1) in ./lib/avs_utils, do

	chmod +x Mak*
	csh Makeall

2) in ./lib/utils do

	chmod +x Mak*
	csh Makeall

That should hopefully do the trick.  Good luck with it!

I'm using AVS to visualize injection mold filling.  The data is in
AVS UCD form.  I can draw isosurfaces that represent the position
of the front of the material that is being injected into the mold.
The modules ucd_legend and ucd_iso are used to do this.  I'd also
like to be able to display the part of the mold that is currently
filled as a solid.  In other words, use the isosurface to cut the
model.  Whatever is on one side of the isosurface, draw as a solid.
I can't quite do this.  The best I've found is to use ucd_threshold
to draw *complete* elements behind the isosurface.  It does not
cut through the elements.  So my question is:  is there anyway to
take the isosurface and use it to cut or slice through the model?
Or is there any other way to visualize what I'm interested in.

of a 3D field, padding the new values with 0's?

Thanks,

David,

Maybe one of these mods could be adapted - in particular glue might do
the job for you.

Good luck with it!

Name        : glue            Version      : 1.000     Mod Number : 1612
Author      : James Pipe, University of Michigan Medical School
Submitted   : 04/10/93        Last Updated : 04/10/93  Language   : FORTRAN
Module path : avs.ncsc.org:avs_modules/mappers/glue
Ported to   : IBM Kubota
Description : Continually pastes on incoming data onto the end of a
              growing output data set - always checking to make sure that
              the dimension lengths of the input and output data sets are
              identical EXCEPT for the dimension in which the glue
              operation is proceeding (also checks vector lengths). The
              parameter 'total sets' is used ONLY for reporting the total
              number of data sets glued together in the current output
              data set - changing its value manually will do nothing.

              useful, for example, if you have a 3-vector 2D field that you
              would like to view with Hedgehog, which requires field 3D
              uniform data.

Hello!!

We have a problem with the geometry viewer:
We wrote a module, which can scale the coordinates of an ucd-structure.
It works.
But the problem is the geometry viewer!! He does not change his picture!!!
If we write out the data after scaling with 'write ucd', the ucd-
structure is corretly scaled. But why does the geometry viewer not
register this??????
Just if you click the read ucd again, the scaling is shown in the geometry
viewer.

How I can avoid this, that I must click the reading again??
It would be nice, if we can change our scaling parameters, and the
geometry viewer show us this directly, without clicking the reading
again.

Any help is welcome.
We are useing AVS 5.0 on an IBM RS6000

Regards and thanx in advance

been able to successfully modify the Network's layout in the Mac software
to make it more esthetically pleasing?

The reason for the inquiry is to provide good hardcopy of Networks for

in the Network to "spruce up" the hardcopy.

Any info is appreciated.  Please reply to the newsgroup.

I have data from a 3D range sensor which is in the form of a
two-dimensional array of x, y, and z coordinates (x, y, and z are
actually in three separate arrays).  I currently read in the data as a
2D irregular field and then use field-to-mesh to convert it into a
geometry.  I then have to use the field-to-mesh scale parameter to
scale the z coordinate to have the correct proportion relative to the
x and y coordinates.  

# AVS field file:
ndim=2
dim1=320
dim2=320
nspace=2
veclen=1
data=float
field=irregular
min_ext=0.0 0.0
max_ext=319.0 319.0
label= range
variable 1 file= ./z.dat filetype=binary
coord 1 file= ./x.dat filetype=binary
coord 2 file= ./y.dat filetype=binary

I have two questions:
1. I am currently using the max value of the field to set the
field-to-mesh scale parameter.  Does this give the z axis the correct
scale? 

2. Is there a better way to work with this surface?

hello!


I made two 3-d objects (from two 'field_to_mesh' modules)
and would like to display them using one AVS geometry viewer to compare
both of them. network is something like....

                |                 |      
           field_to_mesh   field_to_mesh
                    |             |
                    --------------
                         |
                   geometry viewer

it works fine but both objects wrap each other and I cannot separate them
even if I use 'Geometry Viewer' transform selection (of course, first of
all I did choose one of the object in small window in 'Geometry Viewer').

How can I separate the 3-d objects?
(I can separate two '2-d' objects).


thanks in advance.

I've written a coroutine that registers itself with the portmapper as an
RPC service. It works great, but when you trash the coroutine, it leaves
itself registered with the portmapper.

With normal modules you can have a destruction routine, using 
AVSset_destroy_proc, but since coroutines have their own main(), the
detroy_proc never gets called when you hammer them. 

Has anyone worked around this lack of destroy_proc in coroutines? 
There are other ways around it like just leaving the port mapper in the
dark until you start up again later, but that's a little messy.

Thanks,

how about having a "self destruct" button on the control panel for

I need help in figuring out how to make a 3d scatter plot in AVS from an
Excel spreadsheet saved in ascii format. What I have are 3 columns of data,
each representing one variable. I want to plot these three variables in space,
and connect each point with a line. Essentially what I am interested in is the 
trajectory of these 3 variables in space. I believe I must use a 1 dimensional
irregular field, with a vector length of 3 (for the space coordinates of each
point). Assuming that is correct, how would I then display this 1d field as
a volume? How would I connect the points? And if I am wrong, what is the
correct type of field I should use? Ideally, is there a module out there that
does trajectories?

Any help would be greatly appreciated. Thanks.

I have sorta sucessfully compiled the modules, however,

Looking in the AVS Developer's Guide -
the syntax looks correct. The main problem is that I can't read
TIFF files. (I have verify that the TIFF files are readable by
reading and displaying them with xv)

I get the following error message:

TIFFOpen:  : Cannot open.
Couldn't convert file to AVS format!

If anyone has any insights I would appreciate it.

I have EXACTLY this problem.  The relates to my earlier question about
how to copy a UCD structure from input to output, I believe.  It just
so happens that Astrid Kuhr are working on the same problem at the
same time.

I have written a procedure, named Copy_UCD, to piecewise copy the input
UCD structure to the output.  Then, since I am attempting to scale and
rotate this UCD, I modify the node positions and then write
them to the output UCD with UCDstructure_set_node_positions().

It appears that the data are being modified correctly (I verified this in the
debugger), but the change is not always reflected in the geometry
viewer window.  Changing the parameters of my module causes all of the
modules below it to flash, as if they are processing, but the geometry
viewer window does not change.  However -- and this is the strange part --
if I then re-click the filename in read ucd, the modules all flash, and
NOW the geom window updates.

My network looks like this (xform ucd is my module)


         read ucd
            |
         xform ucd
            |
        ucd to geom
            |
      geometry viewer

What could cause this problem?

You could actually set nspace to 3 and read coord 3 as you do variable 1.
This would give you data which occupies 3D space.  Filed to mesh will work on
this and will get it right cos you have specified the Z.  The data value
will also be Z and you could colour the surface in field to mesh with
this value(or indeed any other values available to you).

change this line to
nspace=3

add at the bottom
coord  3 file= ./z.dat filetype=binary

Hope this helps

At the risk of looking foolish: Does anyone know how to erase the contents of
a string typein widget?!

On our system (AVS5/ Sun Sparc/ E&S Freedom) it seems that once something has
been typed or piped into a string parameter no amount of backspace or Ctrl-U
bashing will shift it - the widget itself is cleared but the module continues
to receive the previous value.

Is this something peculiar to our setup or is it a generic AVS "feature"?  Any
ideas for workarounds, short of hammering the module and re-plumbing?

Thanks,

I'm not sure whether your problem is in retrieving a saved geometry or in
printing it out once it's visible in the geometry viewer window.  If it's the
latter, have you tried switching to Software Renderer?  Our hardware renderer
(E&S Freedom) along with many others, I believe, doesn't support the image
output port of the geometry viewer module and just puts out a black rectangle
of the same size as the geometry viewer window.

For postscript output it might also be worth looking at the Command Line
Interpreter command geom_save_postscript which I've only just noticed in the
documentation.
This also works only with the software renderer, but it makes a better job of drawing
lines and text than the image to postscript module since it puts them out as postscript
primitives, whereas image to postscript just copies the bitmap as seen on the screen.
To use it, start AVS using avs -cli, get the scene set up in the geometry
viewer window, switch to software renderer, and then type something like

geom_save_postscript -camera 1 -image xxx.ps

Field to mesh has an odd habit of setting the transformation mode of 3-D
objects to 'parent' You could use the cli so reset the transformation
mode after each execution of field to mesh, but the easiest way to fix
the problem is to use the transform selection mentioned above and turn on
the 'Override' toggle in that panel.  That will make AVS ignore the
transform mode setting.  Credit for this solution goes to AVS technical
support who helped me on this a couple of months ago.

The function registered by AVSset_destroy_proc will get called from
AVScorout_wait or AVScorout_X_wait.  If your code was not in those routines
when the routine is hammered, your code is just sent a kill signal.  You could
try to trap the kill signal yourself.

I tried using a combination of AVScorout_X_wait, XtNextEvent, and XtDispatchEvent
instead of using XtMainLoop, so that 'hammering' my couroutine would call the
destroy function that I had registered (I was doing RPC also).  It was too slow,
I opted for somewhing similar to Wes Bethel's comment about having a 'kill'
button in the interface.

Scott,

I had the same problem with the lack of destructors for 
coroutines! I needed to tidy up some sockets and extra shared 
memory segments that my modules created.

My way around was to use C++! Hence I could make use of the C++
destructors.

This seems to work fine ... mostly ... !

AVS has a nasty habit (I think!) of only trying to clean up for
a certain time length. At the end of that all destructors just
get killed without completing their clean-up.

Hence for large networks, or the system on a go slow, networks
may be terminated but still leave shared memory segments and 
sockets around.

The only workaround that I have found is to only destroy the
modules one at a time.


Mike.

Hey fellow AVSer's,

Does anyone out there have experience with automated connection and
disconnection of module ports?  Before you whip out the "Developer's
Guide" and tell me to use "port_connect" and "port_disconnect", it gets
a bit more complicated.  Try the following CLI commands:

  module "read field" -alias read
  module "downsize" -alias down -postpend read:0
  module "print field" -alias print
  port_connect read:0 print:0

If you look at the Network Editor now, you'll see a connection between
"downsize" and "print field" (since "downsize" was postpended onto "read
field").  Now try to execute the following CLI command:

  port_disconnect print:0 read:0

Since there isn't a connection between these two modules, an error occurs.
The thing is, I know the module I connect to ("print" in this case), and
I'm trying to transparently break this connection through a custom interface.

Is there any other command (other than "port_disconnect") that will disconnect
a port of a single module from it's source (without knowing the source
module)?

I've notified AVS of this peculiarity a while back, but have heard nothing
since.  I've been wrestling with this problem for some time, maybe someone out
there can help me.  Thanks.

  I had similar problems and a kind sole on the net pointed me in the 
right direction.  So here is what I learned.
  First, it is aways better to save as a "scr" from the "write scene" button 
under the camera menu than to save a "geom".  The "scr" retains the colors, 
transforms, lights, etc.  Next if you look at the "scr" you saved there is a 
line at the top that reads "geom_create_scene ---", comment it out.  Now load 
your network and read in the scene, you should now see your object(s) in the 
geometry viewer window and the scene will be available on the output port on 
the right.  Good luck.
  Tip, for making high quality postscript images the bigger the view window 
the higher the apparent resolution of the printed image.  Remember the image 
to postscript module is just a screen capture at approx 100 dpi.

I am also interested in these routines.  Does the fact that there is

that are non-supported?  If that is not the case, please respond to me
