Hi Folks,

The 10 most frequently downloaded AVS modules have been determined
through analysis of our ftp log.  Compressed tar archives of all of 
these binary executables have been created for each of the AVS Consortium 
platforms, as well as an archive of all the source.  These can be found
on the ftp site at avs.ncsc.org:avs_top10_mods/*

Name        : read_tiff       Version      : 2.000     Mod Number : 1159

Description : This module reads a TIFF format file and creates a 32-bit
              ARGB image in the AVS "field 2D 4-vector byte" format. Code
              modified to compile on Sun, DEC, Kubota, Convex and HP on
              12/27/92 - SRT.

Name        : plot_xyz        Version      : 1.000     Mod Number : 1064

Submitted   : 10/10/91        Last Updated : 10/10/91  Language   : C
Ported to   : Sun DEC Kubota Convex HP IBM
Description : This module reads an ASCII file consisting of lists of x,y,z
              points and constructs a polyline geometry object using the
              points in the file as vertices.

Name        : mandelbrot      Version      : 1.000     Mod Number : 1108
Author      : Larry Gelberg, Stardent Computer
Submitted   : 11/27/91        Last Updated : 11/27/91  Language   : C
Ported to   : Sun DEC Kubota Convex HP IBM
Description : Generates the mandelbrot set, at a specific location, for a
              certain number of iterations, at a certain size, all
              determined by paramter widgets.

Name        : contour         Version      : 2.000     Mod Number : 1023 
Author      : Stardent Computer
Submitted   : 10/10/91        Last Updated : 12/16/92  Language   : C
Ported to   : Sun DEC Kubota Convex HP IBM
Description : Finds and creates contour lines of similar value in a 2D
              scalar field. The parameter "threshold" controls the
              level of contour being found. The parameter "new" controls
              the byte value written into a black (value = 0) image as the
              contour. This module could be used to find, for example, a
              contour on the red channel of an image, then overlay it back
              onto the original image. Updated by Steve Thorpe as per
              Susan Katz's suggestion on 12/16/92 to remove the
              informational messages every time it is executed.

Name        : read_gif        Version      : 1.000     Mod Number : 1101
Author      : Larry Gelberg, Stardent Computer
Submitted   : 11/22/91        Last Updated : 11/22/91  Language   : C
Ported to   : Sun DEC Kubota Convex HP IBM
Description : This module reads a GIF format file and creates a 32-bit ARGB
              image in the AVS "field 2D 4-vector byte" format. If the GIF
              file has an embedded color-map, that is used, otherwise, it
              creates a linear grey-scale ramp.

Name        : fast_animate    Version      : 1.000     Mod Number : 1181
Author      : Keith Refson, Oxford University
Submitted   : 04/30/92        Last Updated : 04/30/92  Language   : C
Ported to   : Sun DEC Kubota Convex HP IBM
Description : The fast animate module implements an animation of a
              sequence of AVS geometry files by reading them into memory
              and sending the geometries in rapid succession to its
              output port. By storing the geometries in memory it can
              achieve substantially better animation rates than the use
              of a cycle object in a script would. Furthermore the
              animation rate is independent of the length of the sequence
              until physical memory is exhausted. The module was
              developed for visuali- zation of molecular dynamics
              simulations where the geometries are "ball and stick"
              representations of molecular assemblies, but is not
              restricted to such.

Name        : animate_file    Version      : 2.000     Mod Number : 1135
Author      : Terry Myerson, International AVS Center (NCSC)
Submitted   : 02/24/92        Last Updated : 11/04/92  Language   : C
Ported to   : Sun DEC Kubota Convex HP IBM
Description : anim_fname is used to output a series of filenames for input
              into a reader module. The module inputs an integer and a
              filename base, and output a filename in the form
              "$base.%3d". This module is very useful for a series of
              files containing a time series of data. Bug fixes and
              extensions for version 2.0 added by Wes Bethel, LBL.
