The directories in this directory contain the source for the VOGL library and the library hershey which is for manipulating the Hershey font data. They are as follows: docs contains the documentation such as there is. drivers contains the source to a variety of device drivers, currently restricted to: postcript, sun workstation, apollo workstations, X11 (R2, R3 & R4), tektronix (401x), hpgl, dxy, and the ibm pc cards: hercules mono, cga, ega, vga and sigma. examples contains some C and FORTRAN programs useful both in testing and (hopefully) learning how to use it. hershey contains the source for the hershey library plus the source for generating fonts and the hershey data for the occidental and oriental character sets. Note: as with VOGL this library is callable in C and FORTRAN. src contains the source for the C VOGL interface, and the source for the FORTRAN interfaces where available. If you have a real SGI machine with GL on it, you can simply compile the Hershey library and the examples with "make -f Makefile.sgi". Otherwise, you will have to edit the Makefile to set various options for your machine and type "make". VOGL is a device portable graphics library that tries to be Silicon Graphics Iris GL compatible. Our intention is that any VOGL program will compile unchanged on a machine running SGI GL (the examples do). VOGL is based entirely on our other graphics library VOGLE. While we still regard VOGLE as our main library (it is, and probably will be for some time to come, the one that gets the most use around here), we will gratefully accept any bug fixes or enhancements. As always suggestions are also welcome. This software may be used for any purpose commercial or otherwise. It is offered without any guarantee as to its suitability for any purpose or as to the sanity of its writers. We do ask that the source is passed on to anyone that requests a copy, and that people who get copies don't go round claiming they wrote it (that is why this one has a copyright notice in it, see file COPYRIGHT). Although VOGL is free we will drink any quantity of Beer you send to us. Regards, Eric H.
