Sorry for the short notice but -

The IRIS Explorer Users Group will meet at IEEE Visualization 92 on 
Wednesday, October 21, at 8pm.  The meeting will be in the Park Plaza
hotel, in the Stuart Room.  There will be refreshments served.  We will
have short presentations by Bob Brown of SGI on Explorer 2.0 and by
John Zurawski of Numerical Algorithms Group on their porting effort.
We will discuss Volume 1, Issue 0 of the newsletter which will be available 
(in limited copies) from the NAG table and what the Users Group is to do.

You can get a copy of the newsletter from swedishchef.lerc.nasa.gov in the

This is a symptom of not having XUSERFILESEARCHPATH defined or
missing files /usr/lib/X11/app-defaults/sgi-color{1280,1024}/Explorer

Try 
	setenv XUSERFILESEARCHPATH `/usr/bin/X11/appdefpath`

All of the X attributes that would change based on screen size are put
in the lower level app-default. This includes fonts and geometry.

Be aware that the appdefpath command requires DISPLAY to be set.

Dear Explorer-folks,

Using DataScribe, it's easy enough to read a 2D Uniform Lattice or a 2D
Perimeter Lattice, but I want half of each of these!  Along one axis,
I've got uniformly-distributed points, along the other, I need general
spacing (perimeter-style).

Can anyone suggest how to do this?  

- Is there a module to turn my bounds and Npoints into a perimeter-list? 
- Would I want to do this with 1024 evenly-spaced points 
  (efficiency drop)? 
- Is there a Uniform/Perimeter data type anywhere? 
- Do I really want a 1D (Perimeter) lattice of 1D (Uniform) lattices? 
  (not allowed by DataScribe!)

(if anyone's interested, our data are a set of nice, orderly spectra
taken at varying temperatures, which cannot be guaranteed to be equally
spaced)

Thanks in advance,

-Dick

  Thanks to some help from David Fousler from SGI, I figured out
the bug in the Buggy program.  I had been calling cxOutputDataSet
routine in my routine around my lattice, a then shipping it
down the wire with the cxOutputDataFlush routine.  This worked,
but then the module data wrapper routine followed my good data
with a NULL lattice. This left the output port with NULL hanging
off it when it wasn't connected, causing the funky behavior I was
seeing.

  The moral of the story is to not mix calls to cxOutputDataSet
and cxOutputDataSet in routines that use the module data wrapper.

I have several stacks of images from the
Macintosh program NIH-Image that I would
like to use explorer to display.
The format is simple:

	header->dimx, dimy, # images in stack
	images

I used datascribe to read these but it only
lets me look at hte top image.  I read it in as a vector
and output it as a 3D unif. lattice.

I would like to be able to apply the image routines in explorer
as well as displaying these pictures as volume renderings.
How is this done?   The manual mentions FIT format rgb images,
but references the Imagevision manual to see the format.
Is this what I should be using?  Is this not just converted
to a standard Explorer data type ?

Thanks,

	I am currently creating some geometry with the cxGeoTrisDefine
routine. I have 4096 separate objects which are small "glyphs"
approximately in the shape of cubes. They each consist of 8 points
and require 9 indicies in the connectivity mesh to specify. I've
noticed that Render takes about 5 minutes to draw this set of glyphs.
Since I need to consecutively render many sets of these glyphs, and
save the screen output of each rendering to make a movie, I am looking
for ways to speed up the process. I've thought of using another call,
such as cxGeoCylindersDefine, which lets me define only one object (i.e.
a group of 4096 cylinders) - would this save time rendering ? Also,
I have 2 processors on my machine, is there a way to speed things up
with parallel programming ? Thanks for your help.

Organization: M.I.T. Lincoln Lab: Fine Food and Coffee
Distribution: comp
Date: 15 Oct 92 11:00:22


Module "Reduce" version 0.9 is available for downloading from
Gordon's site at epcc.ed.ac.uk in the /pub directory. I assume the
module will also be available shortly from swedishchef.

----


Reduce ver. 0.9

"Reduce" is a module that performs *true* subsampling 
across a 3D uniform lattice data structure. 

Unlike the (inappropriately named) "Subsample" module which merely
takes 'chunks' out of a data set,
"Reduce" degrades the resolution of a volume data sample so that the
volume can be more easily manipulated by Explorer. The user has 
complete control over the degradation of the voxel resolution for
all three axes. By subsampling across the x/y/z axes, the user
can maintain the x/y/z ratio of the original image.

The indended purpose of reduce is to allow easier, less time consuming 
manipulations of large volumetric data sets within the Explorer scientific
visualization package. Modules such as Contour and Render can more easily
ingest a smaller volume, and allow the researcher to have a faster
response time. When the researcher set up Explorer to manipulate the
volume the way he or she choses, Reduce can be turned off to allow the
full resolution of the data set to be allowed to pass through the pipeline.

There are three subsampling functions that the user can use to 
degrade the resolution of the data set:

	Average:	All voxels within a radius of "n" are averaged
			together to produce the new volume set, where
			"n" is determined by the user's reduction
			percentage.
	Center Point:	Every "nth" voxel is sent to the new volume
			set, where "n" is determined by the user's
			reduction percentage.
	Percentage:	This function is not implemented in this version.

------------

Reduce version 0.9 is fully functional except for the following:

	- Percentage is not functioning
	- x/y/z yoking is not functioning

------------

Hi,

I need to convert a 3D Perimeter lattice to a 3D Uniform lattice.

The main problem is that I need to "resample" the data so that the smallest
volume element from the Perimeter lattice is the size of the uniform lattice
volume.

I suppose that I could do this in C, linearly interpolating the data to
fit the new uniform grid, but I really like Explorer and its bitchin'
DataScribe sibling -- I'd like to do it in DS if possible.

Suggestions welcomed.

Colleagues, 

   I am in search for a computer graphics 3D editing tool to esily
compose RNA and protein spatial structure models at low as well as
atomic resolution. Known structure element coordinates for e.g.
tetraloops, stacks, helices, bends, pseudoknots and for protein
zippers, fingers, sheets, a-helices etc etc should be part of a
toolbox where one can pick structure templates for the buildup.
Structures must be seen and treated with varying detail, for example
an RNA A-helix is either a simple cylinder, a carved cylinder (showing
grooves), same with bases and sugars shown as simple tiles, and with
atoms shown. Only X-ray (and sometimes NMR) data justify the latter,
but lower resolution models from other data can be very useful. I have
seen MacroModel, Insight, Quanta, and brochures for Sybyl/Biopolymer
module. The focus of these programs are either molecular dynamics or
the price is out of line. Would any readers of this know reasonably
priced programs like described, either finished or in the works?
Is this something that can be done under Explorer?

Make sure you have binary mode set when you transfer files.  You can do this
