Does anybody know if there are limits on the number of inputs, outputs and

found?

As much as I like AVS, the default font size is a bit small for my

comment is going to be "Gee that's nice but can't you make the font
bigger?"

So, how can I enlarge the fonts in the AVS objects?

Thanks for the help.

Hello All,
I have an AVS/Khoros question. I am attempting to compile an AVS 
module for edge detection which utilizes the khoros library routines.
I do not have the trillion meg of disk space to install the library. 
The module calls three routines which I assume are in the khoros 
distribution. They are expfilter(), gradadp(), and threshold(). Is it 
possible to just extract these routines from the khoros distribution??
I have loked at an Index for khoros and didn't see them. Am I doing 
something wrong? If anybody knows where the source for these routines 
are located could you please drop me a line. My address is 
	holupka@snips.dfci.harvard.edu
Thanks in advance.

Hi Everyone !!

I am currently doing some work using AVS here at Daresbury 
Laboratory in the UK. I am using AVS3 (Soon to be upgraded)
and would like to now if any one out there has  ported the
AVS module (read_DYNA3D) to the Sun platform. I have tryed
myself but not with much luck.

I recently went  to the  AVS UK user group  meeting at the
Rutherford  Appleton Lab here in the  UK and  heard  Steve
Thorpe  mention  that  the IAC had a program that  allowed
the automatic  porting of code from platform to  platform.
Would this program port read_DYNA3d to the Sun? Has anyone
tried? or better still is anyone going to try in  the near
future.

Alternatively  if anyone out  there is using DYNA3D  data
with  AVS  (version 3, 4  or  beta 5)  would they  please
contact  me  and let  me know  how they are going on!  In
addition  if  any  one  out there  has already  converted
the read_DYNA3D AVS module  to run on  a Sun would it  be
possible  to  post a copy  at the IAC or  directly  to me
as this would be of great help to me.

Good Question.  I am interested in doing the same thing for cockpit 
displays.  My bright idea is to use an existing flight simulator such as 
Microsoft's Flight Simulator Spectrum Holobyte's Falcon 3 and take the 
aircraft's position and attitude data from the modem link that is used for 
playing two games against each other.

Just the other day I asked if anyone had decoded the modem protocol for 
either of these games.  If anyone on this conference has looked into this, I 
would appreciate an reply.  If I get any information from the other 
conferences, I will post it here.

    Hello Steve. You may try to get MAPEDIT from one of your local BBS.

Here's an idea assuming you are working in DOS and using a fairly
common SVGA adapter:

Look for a program called VGACAP, usually downloadable as 
VGACAPXX.ZIP, where XX is a version number (VGACAP81.ZIP is pretty
current).  This allows you to capture the screen to a raw graphics
file (RGB for every pixel).  It comes with a utility to convert the
raw file to a .GIF file.

Then, get "Dave's .TGA Animation Program" (DTAXXX.ZIP).  It converts
a series of GIFs to an Autodesk Animator .FLI file.  (DTA17F.ZIP is
pretty current).

Then, get either QUICKFLI.ZIP (an .FLI player) or AAPLAYHI.ZIP (an
FLI player put in the public domain by Autodesk themselves) to play
the .FLI back.

There are other ways to go if you have the above programs, like
via .TGA etc.

Good luck.

There are several parts of the system to consider:
  * display - 3D graphics concepts at work here (transformations, many
    different coordinate systems to plan into it, etc)
  * actual flight simulation -
    * lots of equations, time constraints, & accuracy are important issues.

The main problem of writing a simulator (for flight, driving, etc) are that
you need to know how to describe the simulated object (plane, car, etc)
with equations.  These equations describe the physical characteristics of
the object, such as power, acceleration, turning radii, lift, frontal drag,
and how these characteristics work together to manipulate the object.

My girlfriend, who is studying aerospace engineering here, told me that
you can represent a plane's characteristics with a large matrix, A.  Then,
the change in these characteristics (such as throttle change, left rudder)
could be in a matrix B.  Another vector X, would represent the current
position, attitude, speed and whatever else of the plane and derivatives of
X would be instantaneous velocities and accelerations of these charcteristics.
What all this boiled down to was an equation like:
    X = A X' + B X''
that you could iterate to find the new positions.  I've never done anything
like this, nor do I claim to know anything about this, so the above equation
may not be right.

The idea is that you will eventually end up with many equations to simultan-
eously solve and you need a good method to do this.  A good method can be
anything that solves the equations within your time constraints.

As far as a textbook approach, I don't know of one offhand - a simulation
seems to be a melting pot of numerical methods you have to know and love.

Sorry there isn't anything more specific in this post.

I am working on a skeletonizing problem also.  I am reading in
scanned images of roots, and trying to calculate the total root
length of the plant.  The most obvious approach (to me) is to
skeletonize the image and take a total length from the number of
pixels.  Is there a better way to do this?  Note that the root
