There is an XOP which has been included with Igor since version 1.24 or 1.25
(current version is 1.26) that loads binary files which I think is called
LoadGeneralBinary.  Check in the Igor ftp archive at d31rz0.stanford.edu
if you don't have it, or contact wavemetrics at wavemetrics@applelink.apple.com.

Good Luck.

Subject: Making movies from a series of images
Organization: Avionics Division, Lockheed Sanders, Inc.
Date: Thu, 21 Jan 93 23:57:32 GMT

We are developing some image generation hardware and need to research some 
quality issues.  Specifically, the quality of motion when the images are 
generated in real time.  I know that anti-aliasing of moving images requires 
some care.

So, given that our hardware simulator (VHDL) can't generate images in 
anything like real time, it is necessary to assemble a series of still 
frames in to a movie.

Can anyone suggest some software that does this?  For platforms, we have 
PC's, Mac's, Indigo's, SparcStations, etc.  On the PC (the platform I know), 
we have MPEG and DL movie players.

My basic notion of the software in question has it taking a series of TIF 
files and compressing/formatting them into an MPEG movie.

Help would be appreciated...thanks in advance.

I use the NCSA hierarchical data format (HDF) to store my simulation 
data.  Now and then I need to plot 1D-data sets or rows or columns of 2D 
data.  For these plotting purposes I have used the Igor software running 
on Macs.  I have some tools, which extract 1D data from the HDF files and 
convert that data to ASCII or Igor Text format.

A more elegant solution in my opinion would be to have an Igor XOP, which 
would extract the 1D data from the HDF file and create a wave out of it 
(a HDFLoadWave XOP).  Unfortunately I am so C-illiterate and short on
time 
that I would not like to start doing such a tool myself, especially if 
someone out there has already done it.

The question is: has anyone out there created a HDFLoadWave XOP or might 
WaveMetrics (or NCSA) be interested in creating such a tool...

Subject: Pyramid Viewers
Date: 28 Jan 93 16:09:25 GMT
Organization: Edinburgh Parallel Computing Centre

I'm looking for any references to work people may have done on methods
of viewing, and visualizers for, pyramidal data structures, typically representing
irregular meshes.

I'm thinkimg in particular of the types of pyramid structure where there are,
say, 4 levels representing nodes, lines, surfaces and elements. Data (scalar or
vector) may be stored along with items at each of these levels, and I'm
interested in different ways of extracting information about the structure in a
sensible and flexible way.

I'm aware of many of the methods, and have coded a few examples, but what we
intend doing is writing a generic pyramidal data structure visualizer, and I'd be
interested in any comments people may have. For example, it is fairly trivial to
get a *basic* view of the connectivity of the mesh by simply plotting the lines -
viewing information at nodes may be done by simply colouring those nodes -
however, when it comes to visualising values at the elements and surfaces, things
start to get interesting......

Does anyone have experience of use of slicing algorithms for such structures ? -
has anyone integrated volume visualisation into such systems ? Is reduction to a
regular lattice/voxel data type structure sensible for further processing ?


I'd appreciate any feedback - of course, if anyone has already done something
like this, then I'd be very happy to hear from them.

Oh - as a bit of an explanation, some people here are looking at hooking such a
visualisation system up to parallel simulations using one of the projects being
worked on here. The plan is to have the paralell utilities library hooked up to a
visualisation system, and updating individual node/face/element values in real
time. The hope is to do things like observe load balancing mesh decomposition
strategies, monitor the progress of mesh based simulations, and eventually have
some sort of feedback control.....

Many thanks,
 
	-G.

If you can afford AVS for your platform, this appears to be a straightforward
plug and play application.  I'm not certain about converting the images from
HDF or netCDF (does pbm do it?), but there is an Animate_File module available
from avs.ncsc.org that would wire up into the Read Image and Display Image
modules.  Run right through them.

Hi, am am wodering if anyone has references on mapping a raster

This seems obvious enough that someone would have tried it, yet I find no 
references in my texts or 3d modeler manuals. The refernces I see on mapping
raster are all directed at "texture" mapping, were a relative small piece of raster
is used to tile a model to make give the model the appearance of being

Please direct responses to me, and if I get fun references, I'll post a summary.

Hello,

I'm going to write a program to view map data efficiently (vectors, areas,
symbols etc). I don't want to use a fully configured GIS program.

The question is to find a suitable library/toolkit to base such an utility
on.  The library must handle vectors, filled polygons, raster and vector
symbols.  It should be possible to use vector symbols to draw lines for
example.  The viewer will be 2D, but 3D might be needed later.  I want
to use my own datastructure for storing map objects (i.e attributes to
a land area object describes the color and fillstyle for the area).

I'm looking for "the best" library for this, i.e the right tradeoff between
speed/flexibility/coding complexity.  I'm thinking in the lines of 
Xlib, PEXlib, OpenGL, PHIGS, GKS, Uniras, ???

Any recommendations/experiences with these or other ?

thanx,

	-jon

Unidraw is a MacDraw-like programable-extendable toolkit distributed
in the /contrib/.../interviews/ section of X11.
You would add your method of reading and writing data files to the program.
You might also add more complex drawing objects than the usual MacDraw primitives.
I've seen it extended to circuit design, graphic design,
and geologic modelling.
It doesn't have 3D. It is object-oriented in C++.
