[ABU] 7-aug-2007 v 1.0 (obsolete)

[ABU] 9-aug-2007 v 1.1

   * Updated links and screenshots.
   * Coherent look&feel on various platforms ; Tested on WinXp, MacOs, Linux

[ABU] 19-feb-2012 v 1.2

   * Fixed error in [setLightVector] - Now vector is normalized
   * Changed formula for Specular Light:
     Now a pure "Phong model is used"
     Previously the half-vector was used (as approximation of 
     Reflection-Vector); Now a real Reflection Vector is used.      

----

Based on work of G.Sookahet [Simple raytracing], here is a more interactive program.

Shading now uses the "Blinn-Phong Shading Model" for handling specular reflection, too.

Note that the geometrical model has been simplified (this implies faster processing-time).
   * The sphere is centered in {0,0,0}, with radius 1.
   * The viewer and the light-source are at infinity (i.e. all light-rays and view-rays have a constant direction)
