What I am not understanding? Peter Well, "Triangle Groups" is supposed to appear in the browser labelled "External Modules" in the lower lefthand corner of the main panel. The external modules are hooked up to geomview by way of the system-wide ".geomview" startup file in the $GEOMROOT data directory. When I retested the distribution package, the mechanism that sets the GEOMROOT variable to the directory that the distribution is unpacked in worked correctly. The systemwide startup file also sets the background color to grey instead of black. If your camera windows are coming up with a black background, then the systemwide startup file is never even found. Guess #1: Did you move the GEOMDATA directory without modifying the Makedefs file referred to below before compiling? Here's the relevant part of the README file: 4. If you plan to install Geomview in some directory outside of its source tree, edit the file Makedefs in the GEOMROOT directory. That file contains comments telling you what to do. If you plan to leave Geomview installed in its source directory, you may skip this step. And these are the relevant comments in the Makedefs file: # GEOMDATA should be the absolute pathname of a directory which # Geomview will search for data files. This directory may contain # sample input files, and/or a file named ".geomview" containing # commands which Geomview will execute upon startup. If you leave # this blank, the makefiles use a default directory distributed with # Geomview (the "data" directory). If you put something here, it is # your responsibility to install the example files from the "data" # directory into this directory (the makefiles will not do it # automatically). GEOMDATA = If your background is coming up grey but nothing appears in the "External Modules" browser, try looking at the systemwide .geomview file. Guess #2: You didn't move the GEOMDATA directory but for some reason the systemwide .geomview file is still not being invoked. Copy it into the same directory that you call geomview from: does this solve the problem? It should look like the one below, but with different (and correct!) pathnames at the end of the "ui-emotion-program" lines. If the pathnames are incorrect, the lines "Triangle Groups" and "4D Rotation" should still appear in the External Modules browser but clicking on them will cause an error. # This is a sample Geomview startup file. You can put commands here # which will be executed by Geomview each time it starts up. Comments # start with a '#' and go to the end of the line. # You should wrap all commands in this file in a "progn" to # cause them all to be interpreted at the same time. # The following commands simply reset some of Geomview's hardwired # defaults; they are listed here just as an example. (progn (backcolor allcams .33 .33 .33) # set all cameras' background color to grey (bbox-color allgeoms 1 1 0) # set all geoms' bounding box color to yellow # Make the example programs appear on the "EXTERNAL MODULES" menu (ui-emotion-program "Triangle Groups" "/usr8/geom/devel/ngrap/bin/sgi/Trigrp") (ui-emotion-program "4-D Rotation" "/usr8/geom/devel/ngrap/bin/sgi/4drotate") ) Sorry about the late response. Let me know if either of the above guesses were correct (guess #2 indicates a bug on our part) or if neither helped. -- Tamara Munzner ((555) 555-5555 munzner at geom.umn.edu The Geometry Center
