The first thing I want to do is change the program to behavior I
believe should be standard for most of its type. When the user
executes the program without args it should display help. For
example, executing metaball now yields:
$ metaball
Removing "metaball.g".
What??
My mod causes it to yield:
$ metaball
Usage:
/usr/brlcad/bin/metaball [-h] [-n number of frames] [-m method] [-o
outfile]
-h Show help
-n # Number of frames to (objects) to create
-m # Metaball render method (1 for iso, 2 for Blinn)
-t title Title of geometry
-o file File to write to
-g Gravotronic animation
-c # Number of control points (require Gravotronic mode)
I tried to fiddle with the "get args" loop:
while ((optc = bu_getopt(argc, argv, "Hhm:n:o:t:")) != -1)
but didn't have any luck, so I kludged it by adding this just in front
of the loop:
if (argc < 2) {
/* tell user what to do */
printf(usage, *argv);
return EXIT_FAILURE;
}
