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)
