GeomFLoad

[fowler]

GeomFLoad does exactly that.  The syntax is just:
Geom *g;
g = GeomFLoad(filepointer, "filename");

The first arguement is the file pointer (eg stdin), the second may be
a char * to the name of the file.  This string is used only in error
messages; it's ok to leave it NULL.  A lot of external modules use
this; pssnap is the first example I can think of (look in
pssnap.main.c [in /u/gcg/ngrap/src/bin/pssnap/sgi or in the tar file
in the ftp directory]).

I wrote a program called warp which performs R^3 to R^3 mappings.  It
includes a library called pointlist which allows you to get and modify
the list of points in an OOGL object without worrying about what kind
of an object it is.  I'll try to get warp (& pointlist) in the ftp
directory by Wednesday, or you can look in
/u/gcg/ngrap/src/lib/pointlist.  There's also a man page for it in
/u/gcg/ngrap/man/man3/pointlist.3  Warp itself will not work except
under geomview 1.3, but the pointlist stuff should work with any
version.
