I located this book, but I can't seem to find any information on it
other than the book exists and you can buy it. What is the general
community opinion of the book? Do you buy the book because it is the
only one which covers object graphics? Or do you buy it because it is a
very useful companion for the object graphics programmer?

Also, how old is the book? And the related question, how much has
object graphics changed since it was written? Basically, how out of
date is it?

I've done limited work with OpenGL and some with Java3D (which is Java
wrappers above OpenGL), so I'm familiar with the concepts used in the
graphics. My problem is that I'm having quite a time trying to figure
out how IDL has "wrapped" the OpenGL underneath. The IDL -> OpenGL
mapping is what I meant by wanting to understand "what's going on inside
the object graphics system."
