This directory contains the beginnings of a more substantial
demonstration.  The program requires motif to compile and run.  I
havent attempted to use lesstif with this demonstration - I believe
that UIL support in lesstif is still very green.

The code illustrates in more detail the use of the X11 specific
interface to lib3d, the use of the new Scene abstraction and the
new FileDevice class.  

The demonstration renders only when necessary, and correctly accepts
resize and expose events.

The files in this directory are not yet under autoconf control, so
you may have to play with the makefile directly to compile on your
system.

Invoke the program:

$ ./viewer ../../models/teapot.nff

It only understands nff files for now.  You can move the camera and
rotate the model by clicking a mousebutton and moving the mouse.  

The camera starts at the origin - right in the middle of the teapot.
