3DMA-Rock runs under Unix/Linux operating systems. We have developed it under the RedHat operating system for releases RH6.X through RH9.X, and RH Enterprise Linux Version 4. It has also been run under SGI Irix and SUN UNIX operating systems.
In addition, the latest version (3dma_rock_1205) has been compiled on Microsoft Windows using the Linux emulator software Cygwin, version 1.5.18-1 (www.cygwin.com).

3DMA-Rock produces three types of graphic plots: x-y plots displaying results from statistical analyses, 2D views of slices from the image (aligned perpendicular to the z-axis) showing the user's data set during manipulation, and 3D plots. Processing and/or display of these plots utilizes inexpensive software.

• The x-y plots are written in "Jgraph" (James Plank, U. Tennessee)

  http://www.cs.utk.edu/~plank/plank/jgraph/jgraph.html

  which is a readable, highly intuitive, text based, plot scripting language. A version of "Jgraph" is included ("3dma_rock/bin/JGRAPH/") with the 3DMA-Rock distribution. "Jgraph" produces encapsulated Postscript output which, under Unix/Linux, can be displayed via the Postscript interpreter "ghostview"

  http://www.gnu.org/software/ghostview/ghostview.html

  distributed by the GNU opensource consortium. "ghostview" is available through the standard RedHat Linux OS distributions up through RH8.0. Under RH9.0 it is replaced by "Gnome ghostview" ("ggv", Gnome.org)

• Two dimensional slice plots are printed as files in SUN RASTER ("*.ras") format. The files are compressed using the GNU "gzip" ("*.gz") facility. Under Unix/Linux, these slice plots can be displayed via "xv" (John Bradley, Trilon)

  http://www.trilon.com/xv/

  One advantage to "xv" is that it recognizes "gzip" compression files (extension ".gz").



• 3D graphics are output in two formats, Inventor and OOGL (Object Oriented Graphics Language). While utilizing Inventor format requires purchasing a commercial license for viewing software, the OOGL format can be viewed utilizing Geomview, a publically available, open-source, 3D viewer for Unix/Linux.
  If you are performing Geomview installtion using Cygwin on Microsoft Windows, the following web page, http://www.ee.surrey.ac.uk/Personal/L.Wood/software/SaVi/building-under-Windows/, provides useful instruction.
