My current experience with OpenGL is limited to C (never even seen Open  
Inventor) on NT 3.51.  I have old copies of the ARB red and blue books.  
  I may get a new copy of the red book.

Is this the book you're talking about?

http://www.amazon.com/exec/obidos/tg/detail/-/0201773430/ 
qid=1105706004/sr=1-6/ref=sr_1_6/103-7830410-3763846?v=glance&s=books

I'll have to think about that.  I'm hoping I can get by with the Apple  
provided documentation:

http://developer.apple.com/documentation/GraphicsImaging/OpenGL- 
date.html

Although I will probably use the local copy I have from installing  
Xcode.

Bookmarked!  This should help.

I looked it up here:

http://cl-sdl.sourceforge.net/

It does indeed look old.  I'm not really interested in the libsdl part  
either, just OpenGL wrappers.  Maybe I would be better off just using  
the OpenMCL FFI.  I don't know yet.  I've gone ahead and downloaded  
0.2.2 to have a look at it.

I'll take a look at that.

BTW, has anyone done anything along the lines of implementing a CLOS  
analog to Open Inventor?
