[ABU] 7-aug-2007 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) [http://web.tiscali.it/irrational/tcl/archive/RayLab-01.png] Download at [[http://web.tiscali.it/irrational/tcl/archive/RayLab-1.0.zip] ''[DKF]: Neat!'' ---- [[[Category Graphics]|[Category Mathematics]]]
