NAME
     NCSA XDataSlice - interactive 3D data analysis tool

SYNOPSIS
     xds [-adjustToggles] [-installCMap] [-noInputFocus] [ -Xop-
     tions ...]

DESCRIPTION
	  NCSA XDataSlice (xds) is a 3D interactive data analysis
	  tool that features several methods of examining a 3D
	  array of floating-point numbers.  One prominent
	  analysis method is to take 2D slices of the 3D dataset,
	  along the cartesian axes, or at any arbitrary angle.
	  The sliced numerical data is then converted, on the
	  fly, to raster images for the purpose of being better
	  visualized and understood.  If desired, the numerical
	  slice can be placed in a scrollable spreadsheet, with
	  its corresponding image placed beside it for reference.

	  Several slices can be generated as a batch with a
	  user-specified increment along the axis orthogonal to
	  each slice, and they may be tiled alongside one another
	  for comparison.  Alternatively, they may be overlayed
	  on top of each another as an animation sequence, thus
	  allowing the use of time as a third dimension in
	  visualizing the 3D dataset.

	  The relationship of slices orthogonal to one another
	  may be further examined by locating them together in
	  the 3D bounding box outlining the limits of the
	  dataset.  The cartesian dicing tool built into XDa-
	  taSlice is used for this purpose.  Slices of various
	  thicknesses or boxes of different sizes may be selected
	  and rendered in the 3D matrix with hidden surfaces
	  removed, allowing the user to view only what he/she
	  deems interesting.

	  If the data in the 3D dataset is sparse or concentric,
	  it is more useful to view the 3D dataset as a whole.
	  The volumetric renderer featured by XDataSlice allows
	  the user to assign various transparency values to any
	  number of substances (defined by ranges of values in
	  the dataset) that he/she may be interested in.  These
	  substances may then be rendered together, and the
	  results are translucent images akin to that of X-ray
	  photographs.

	  At times, it may be desired to map out iso-surfaces
	  within the 3D dataset, just as one would want to get
	  contour plots of 2D images.  The iso-surface renderer
	  in XDataSlice is sufficiently equipped to perform 3D
	  edge tesselation and render the surfaces (with hidden
	  parts removed) with a single light source.  Views may
	  be rendered with perspective projections and rotated at
	  any angle about the X-, Y- and Z- axes.  Animation
	  sequences showing the views being rotated in space may
	  also be batched generated.

	  XDataSlice provides the ability to change the colormaps
	  used for the generated images.  These color maps may be
	  created by NCSA XImage (ximage), or some other NCSA
	  software packages.  All generated images may be saved
	  in the NCSA Hierarchical Data Format (HDF) for further
	  analysis by XImage or other software.  They may also be
	  read by XDataSlice for review.

	  As input data, XDataSlice takes HDF files containing
	  either 8-bit raster data or 32 bit 3D floating point
	  data.  NCSA HDF is a standard data format originally
	  developed at NCSA.  As input palettes, it takes in HDF
	  palettes, and 8 bit palettes where the first 256 bytes
	  specify the 256 entries of red, the next 256 bytes
	  specify 256 entries of green and the the last 256 bytes
	  specify the blue component.

     Full documentation of NCSA XDataSlice is provided along with
     the distribution.

1 November 1989                                         XIMAGE(1)



NAME
     NCSA ximage - interactive data analysis tool

SYNOPSIS
     ximage [ -options ...]

DESCRIPTION
	  ximage is a 2D interactive data analysis tool that
	  features displaying color images of data sets in carte-
	  sian and polar form.	It can display the actual data
	  values in a spread sheet manner and create color con-
	  tour plots, shaded images, color histograms, and pro-
	  file plots.

	  ximage provides functions for dynamically manipulating
	  palettes. Palette manipulation may be done by changing
	  the component values in RGB, CMY or HSV color models.
	  In addition, the palette may be changed by expansion,
	  compression, rotation or transposition.

	  The user may animate multiple raster images from disk
	  or the X server's memory.

	  As input data, ximage takes either 8-bit raster files
	  or HDF files containing either 8-bit raster data or 32
	  bit floating point data.  HDF (Hierarchical Data For-
	  mat) is a standard data format originally developed at
	  NCSA.  As Input palettes, it takes in HDF palettes, and
	  8 bit palettes where the first 256 bytes specify the
	  256 entries of red, followed by 256 entries of green
	  and then blue.

X DEFAULTS
	  ximage*installCMap: (True or False)

	  installCMap tells ximage whether or not to follow ICCCM
	  rules for setting colormap.  If you are using an old or
	  non ICCCM compliant window manager, this option should
	  be set to True.  The default is False.  If the color
	  map does not appear to be changing when a colormap is
	  loaded then changing this option will usually fix the
	  problem.

	  xds(1)    - NCSA XDataSlice

	  Full documentation of NCSA XImage is provided along
	  with the distribution.  The latest version of this
	  software and documentation may always be obtained from
	  the anonymous ftp server ftp.ncsa.uiuc.edu
