( XTHING, MOTIF_TOYS, A Visualization Tool  E     XTHING is a tool I wrote for the use of displaying 3D data in 2D. D     Most of the packages we had only displayed in 16 colors, I brokeB     that barrior.  XTHING takes a file of data and plots it in n-1D     colors where n is the number of colors available on the display.E     It compresses points either linearly or logarithmically, displays A     the data in color (HSB) or gray scale, zooms, and does period F     repeats of the image.  It also outputs in postscript (which post.c-     might be handy for a slew of programs...)   E     I wrote XTHING on an IBM/RS6000 but have successfully compiled it >     with no changes on VAX VMS systems.  Plus (if you have the/     memory) I have plotted over 800,000 points.          John L. Cwikla:       Materials Research Laboratory Center for Computation       University of Illionois      
