Expressions of interest: GLUT Inventor Adaptor for Win32/Linux

[Nigel Stewart <nigels@xxxxxxxxxx>]

I've been tinkering away at a C++ adaptor for GLUT and Inventor
as part of the GLT (OpenGL Tools) library which is GPL and
currently supports Win32 and Linux.  The problem is that Christmas
is fast approaching and it doesn't seem that I will have time
to keep fiddling in Linux (Madrake 7.2) to get Inventor to
compile so I can do a release of GLT with this new feature.

If there is anyone here with a working Linux/Inventor installation
and is willing to do some compiling, testing and trouble-shooting,
please email me at nigels@xxxxxxxxxx  I don't believe that
there will be any major issues, but I just don't have the 
opportunity to try the latest CVS snapshot on Mandrake to do
this for myself.

I'm also keen to support other Unixes or operating systems.

For a demo of Inventor examples on Win32 including ivclock, maze
and some Inventor Mentor examples, have a look at:

http://www.nigels.com/glt/gltInventorDemo0.3.tgz

These are precompiled Windows EXE and DLL.  Mouse, keyboard and
time events are all implemented - perhaps not to perfection,
but certainly to a useful extent.  They depend only on 
INVENTOR.DLL and GLUT32.DLL, which are included in the archive.

Just repeating the point of this project - to combine the
power and flexibility of Inventor with the portability and
simplicity of GLUT.  (Well, also to provide a nice and
clean object-oriented C++ wrapper for GLUT)  The scope of
Open Inventor integration is all scenegraph functionality
upto the SoSceneManager level.  (ie. No OS-specific user
interface components, etc)
