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)
