Da ein raytracer in comp.sources.unix ankam, dachte ich mir, den kann man gut
zum benchmarken nehmen.

Hier sind die Resultate ( rayshade -v -O balls.rla balls.ray ) , ich
faende es gut, wenn jemand das auch mal auf einem 80386 er laufen laesst.
Ich habe die source nur dahingehend modifiziert, dass er Wavefront format
schreibt. Ich poste vielleicht noch einen bench fuer eine HP.
