GLUT Open Inventor users,

BUILD INSTRUCTIONS
===================

To enable building of the GLUT Open Inventor examples (assuming
an Silicon Graphics workstation running IRIX), do the following:

  1)  Make sure you have the Open Inventor development (inventor_dev)
      and the C++ development (c++_dev) products installed.

  2)  Run "mkmkfiles.sgi" in this directory.

  3)  Create a file in this directory called Inventor.mk with
      the following line:

INVENTOR = inventor

  4)  Execute "make" in this directory.

NOTES
======

  o  The GLUT Open Inventor examples can be found in the
     progs/inventor subdirectory.

  o  To build the progs/inventor subdirectory if you use Imakefiles,
     try:

cd progs
make SUBDIRS=inventor Makefiles
cd inventor
make

     Since I'm not familiar with how Open Inventor is installed on
     non-Silicon Graphics machines, you may have to adapt the Inventor
     related lines in Glut.cf to your system's Open Inventor
     installation.

  o  Using the Imakefile requires an X11R6-based set of
     /usr/lib/X11/config rules that support C++.

  o  When you use Open Inventor with GLUT, you can access all
     the non-window system based features of Inventor like the scene
     graph, etc.  Specifically, you won't be able to use the
     SoOffscreenRenderer or SoXt based classes.

  o  Link with -lInventor instead of -lInventorXt to make sure
     you only get the non-window system based features of Inventor.

  o  See Chapter 17 "Using Inventor with OpenGL" in the Inventor
     Mentor (Addison-Wesley, ISBN 0-201-62495-8) for a discussion about
     using Open Inventor outside the context of Open Invetor's Xt
     widget frame work.
