Light Torus : Animating Lights over the objects


torus

Description: Program to demonstrate how to add lighting and material properties to a torus.This program extends the program Wrap Torus.  The triangles or quadrilaterals are wrapped around the torus in a single long strip.


USAGES: There are a number of keyboard commands that control the animation.  They must be typed into the graphics window, and are listed below

     Press the "r" key to reset the torus back to initial position, with no rotation.
     Press "0" (zero) to zero the rotation rates.

   CONTROLLING LIGHTS:
