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.
