Input data comes in the form of two 2D arrays - each with a single variable at every node. These arrays can be image data, floating point data, or any combination therof. The first of the two arrays is used to create the height geometry where the indices of this array are used to form the X-Y coordinates and the variable at every node is used as the Z coordinate in a cartesian coordinate system. The second of the two arrays is assigned a color at every node through one of many available visualization representation methods. This resultant color field is draped over the height geometry. Both fields are assumed to have the same input dimensions establishing a unique one-to-one correlation of the respective data values in each of the two data sets. The analysis of the correlation of data thus becomes as easy as associating regions of varying height with coincident regions of color. Height-Color Visualizer has been set up as a non-interactive batch utility to enable users the ability to create 3D animations from time-dependent data with little effort. Height-Color Visualizer was written at the National Center for Supercomputing Applications (NCSA) located at the University of Illinois, Urbana-Champaign. The software was developed by NCSA's Software Development Group using the new Renaissance Experimental Laboratory (REL) located in the new Beckman Institute for Advanced Science and Technology at the University of Illinois. The purpose of this experimental lab is to provide state-of-the-art computer graphics equipment for a prototypical, interdisciplinary educational and research environment that focuses on computer graphics and scientific visualization.

To extract the files from 'hcvis.tar.Z', type the following: uncompress hcvis.tar.Z tar -xvof hcvis.tar This will create a directory called 'HCVIS' with several sub-directories below it. After you extract all the files with the above command, you should read all the README files in the respective directories for a complete description of HCVIS. The file 'hcvis.version' is a text file which contains information about which release of hcvis is contained in hcvis.tar.Z. -------------------------------------------------------------------------------- ******************************************************************************** Arnold Nipper *** Universitaet Karlsruhe, Am Fasanengarten 5 * nipper@ira.uka.de XLINK, Inst. fuer Betr.- und Dialogsysteme, D-7500 Karlsruhe * +49 721 608 4331 ********************************************************************************
