This directory contains demos that use the Panel Library by NASA Ames.
They only run on SGI machines and require the 'pnl' and 'gl' built-in
modules.  Each subdirectory contains one demo.

apanel		A trivial user interface to the audio capabilities of
		the 4D/25 (Personal IRIS).  Lets you record a sample and
		play it back at different volumes.  Requires the 'audio'
		built-in module.

flying		A large demonstration that can display several
		differently shaped objects through space.  Control
		panels let you manipulate light sources, material
		properties and drawing modes.

nurbs		A demo of the capabilities of the GL 'nurbs' functions
		that can display the control points.  (It was intended
		to let you move these as well, but there was a problem
		with the mapping of mouse movements in a 3-D world.)

twoview		A demo of GL's transformation primitives.  Two views on
		a scene are given, and the position and orientation of a
		viewer in one of the views can be changed through
		various buttons and dials in a control panel.
