Changing the Way You See Science

The NCSA Scientific Visualization Software Suite
for the Macintosh

NCSA DataScope
NCSA DataScope features distribution capabilities across TCP/IP network 
connections.  This interactive data analysis tool displays 32-bit 
scientific data values in spreadsheet form or as simple scaled, 
interpolated, or polar color raster images.  It also acts as an output device 
for 2D arrays of floating-point numbers.  Furthermore, while most 
supercomputer simulations write out results in ASCII or binary data files 
from which you can create graphs or images, DataScope allows you to 
bypass this intermediate file because it displays a data image 
immediately on the screen, even while generating the image's values. 
Other features include synchronized selection capabilities between text 
and image windows; evaluation of mathematical expressions to derive 
new datasets; built-in functions; a notebook window for recording 
observations and calculations; and support for functions contained in 
external libraries.

NCSA Image
NCSA Image is a color-imaging application that displays and animates 
8-bit binary scientific data as color raster images, and generates black-
and-white contour, ordered dither, shaded data, and 3D plots.  It lets you 
plot linear selections of data in a XY graph, perform histogram color 
adjustments on raster images, animate multiple raster images, print any 
of the black-and-white plots switch and manipulate palettes, and view 
actual floating-point numbers.

NCSA ImageIP is a color imaging and analysis program that retains the 
capabilities of NCSA Image, but adds the more common functionality of 
image processing programs which allow actual manipulation of image 
data.  Features include the modification of the dataUs histogram, 
modification of data contrast, operations on the data using non-linear 
filters and convolution kernels, and useful utility functions.

NCSA Layout
NCSA Layout permits batch capabilities that generate animation 
sequences on the Cray or other UNIX systems.  It is a presentation tool 
that allows you to display and annotate 2D data images so that you can 
photograph your Macintosh screen display with a 35mm camera and 
produce presentation-quality slides.  It lets you annotate images with grid 
lines, tick marks, text, color bars that display the range of the current 
palette, a colored canvas, and graphics from non-NCSA software such as 
MacDraw, PowerPoint, and PixelPaint.  Furthermore, NCSA Layout offers 
options for enumeration of each animated frame, multi-image display in 
animation frames, halftone printing, scrolling windows, canvas sizing, full 
overlay capabilities, and transparent text and colored background options.  
You can save a layout as an HDF file for editing at a later date, or you can 
save any part of a layout as a raster image that may be transferred to 
other machines or programs for photographing, animation, or display.

NCSA PalEdit
NCSA PalEdit is an interactive palette creation tool that helps you produce 
a 'clut' resource tailored to your needs.  It allows you to combine, adjust, 
and make range selections in palettes from any combination of 
components from four color models-RGB, CMY, HSV, and HSL.  One tool 
option permits you to distinguish between modification of whole color 
regions or only active component colors.  In addition, you can copy and 
save new or modified palettes in five different file formats:  raw palette, 
HDF, Klutz DA, Canvas, or PixelPaint.

NCSA Telnet
NCSA Telnet is the Macintosh's link to the TCP/IP networks.  It is an 
implementation of DARPA standard telnet that provides interactive access 
from any Macintosh to telnet hosts on TCP/IP networks; lets you have 
simultaneous connections to numerous computers across the network, and 
includes a standard file transfer server (FTP) to allow you to share files 
with other remote machines and user's; VT 102 emulation; Tektronix 
4014 emulation; interactive color raster graphic capabilities; domain name 
lookup; user-defined macro keys; full color, font style, and font size 
support; and customized windows whose contents may be scrolled, cut, 
copied, pasted, and printed.

NCSA HDF, or Hierarchical Data Format, is a multi-object file format that 
facilitates the transfer of graphical and floating-point data between 
various machines and operating systems, including the Cray, Sun, Alliant, 
Silicon Graphics, Macintosh, and IBM PC computers.  HDF allows self-
definitions of data content and easy extensibility for future enhancements 
or compatibility with other standard formats; includes Fortran and C 
calling interfaces; utilities to prepare raw image of data files or for use 
with other NCSA software; and interface for storing and retrieving 
compressed or uncompressed raster images with palettes; an interface for 
storing and retrieving scientific datasets of up to seven dimensions 
together with information about the data, such as labels, units, formats, 
and scales for all dimensions.

Other Releases

NCSA CompositeTool for the Sun Workstation
NCSA CompositeTool is a presentation tool that lets you annotate 2D 
images so that you can photograph your Sun screen with a 35mm camera 
and produce presentation quality slides.  It allows you to create a display 
using a user-defined palette, color bars, grid lines, XY axes, tick marks, 
text tilting, multiple raster images, contour intervals of a 2D data image, 
and vectors of 2D data.  Moreover, you may perform screen dumps of 
selected portions of your layout, and store and retrieve layouts to be 
photographed or edited at a later date. CompositeTool features NCSA HDF 

NCSA Contours for the Macintosh
NCSA Contours is a simple graphics tool that represents 2D raw raster 
scientific data as contour, 3D, and shaded data plots.  It supports the 
Macintosh desk accessories and cut, copy, and paste features and allows 
you to print and save all or part of a plot in PICT format, which can be 
read and manipulated by such commercial software packages as 
SuperPaint, CricketDraw, and MacDraw.

NCSA GelReader for the Macintosh
NCSA GelReader is a color-imaging and analysis tool developed for 
molecular biologists or others in need of electrophoretic gel data analysis.  
The program extracts information from digitized electrophoretic gel 
images such as DNA fragments.  Allowing interactive manipulation of 
lanes and bands, the tool helps estimate the molecular weight of bands as 
well as generate reports of them.  NCSA GelReader was created with the 
assistance of UIUC's Center for Prokaryotic Genome Analysis (CPGA). 

NCSA HDF Vset is the latest storage scheme in HDF (Hierarchical Data 
Format).  It can accommodate existing HDF data elements (e.g., raster 
images, scientific datasets, palettes, and annotations) as well as varied, 
irregularly structured and nonuniform datasets of any size and 
dimension.  Specifically, HDF Vset makes the following two features 
available to you:  (1) All kinds of regular (array-type) and irregular 
datasets may now be stored in one finite-element data, spreadsheets, 
splines, non-Cartesian coordinate data, etc., and (2) Related and diverse 
datasets can now be linked together hierarchically to form logical 
groupings.  Calling interfaces are available for C and FORTRAN on 
Cray/UNICOS, Suns, SGIs, and Vax/VMS.

NCSA Height-Color Visualizer for SGI Systems
The NCSA Height-Color Visualizer is a non-interactive batch utility that 
enables you to easily create 3D animations from time-dependent data.  
Input for the Height-Color Visualizer consists of two 2D arrays, each 
having a single variable at every node.  Using the program, you can 
manipulate the first of the two arrays to create a height geometry, so that 
both fields assume the same input dimensions.  Thus the analysis of the 
correlation of data in the NCSA Height-Color Visualizer is as easy as 
associating regions of height with coincident regions of color.

NCSA HyperCard Scientific Animation Package for the Macintosh
The NCSA HyperCard Scientific Animation Package allows you simply and 
efficiently to create a movie animation of a series of graphic images.  It is 
an add-on XCMD for HyperCard that imports sequences of graphics images 
into a Hyper-Card stack of cards.  Specifically, the package allows you to 
translate graphics images, typically created on the Cray supercomputer 
and translated into a series of Tektronix 4014 drawing commands, into a 
PICT file; read the resultant file into a HyperCard stack; and animate the 

NCSA ImageTool  for the Sun Workstation 
NCSA ImageTool is a color-imaging application that displays 8-bit binary 
scientific data as color raster images or black-and-white contour, shaded 
data, ordered dither, or 3D plots.  It allows you to plot selections of data in 
XY graphs; print contour plots, 3D plots, and XY graph; and modify and 
save color palettes.

NCSA PC Show for the IBM PC, XT, AT, and PS/2
