The Performer programmers guide is your best bet to learn about
Performers pfNode types. Run insight and select the `SGI Developers'
bookshelf find `IRIS Performer Programmers Guide' on the list above.
Read chapter 3, to learn about pfNode types, actaully you should read as
much of the book as you can. Chapter 9 describes pfGeostate features
like texturing.

To see the Performer database structure graphically load your model into
perfly hit the h-key. As you highlight nodes in the tree display they
will highlighted the geometry in your scene. Look at the perfly console
to the left because there are controls to manipulate the scenegraph tree
display. I think once you see the graphical view of the scenegraph the
printed version will make much more sense.
