Installation of FLUDViz: UNIX Executable

Requirements
and
Implementation

• uses GLUT/Tk which needs to installed separately.
• depends on common Web Metrics resource code; you must install these resources before running FLUDViz.
• invokes Xlib for graphic input (mouse, spaceball, keyboard) and exchanges information with the Tcl/Tk menu via generated X events. Thus it is assumed that you are running an X client.
• uses the GLX library (extensions to X Windows for OpenGL) for 3D graphic output, so your X client (your terminal) must be able to execute GLX commands.
• uses a few Unix system calls (system, getenv).
• uses the BROWSER environment variable to select a web browser for text display and to show pages of website. (Tries to use mozilla, netscape, or lynx by default.)

Download

On your machine, create a "WebMetrics" directory to serve as the root of the standard directory structure for WebMetrics, and create the corresponding environment variables if they do not already exist. Code specific to FLUDViz will be stored in $WEB_TOOLS/FLUDViz.

Go to our NIST Web Metrics download page to download the FLUDViz software. Copy FLUDViz-xxx.tar.gz into the $WEBMET_TOOLS/ directory (where xxx = the name of your specific unix operating system). Then do:

   gunzip FLUDViz-xxx.tar.gz 
          (to produce FLUDViz-xxx.tar)
   tar -xvf FLUDViz-xxx.tar
          (to generate FLUDViz tree)

FLUDViz Files

   FLUDViz directory
      fludviz        - OpenGL executable
      fludviz.tk     - Tk script for the control menu
      README         - Pointer to the documentation web site

Preparation
and
Cleanup

FLUDViz needs one additional environment variable CHAR_GEOM set to $WEB_TOOLS/resources/ogl/char-geom.dat. If FLUDViz cannot find this file it will produce lots of error messages about it.

You are now ready to operate FLUDViz.

You can delete the original *.tar file to save room, if desired.
