Rhino is an open-source implementation of JavaScript written entirely in Java. It is typically
embedded into Java applications to provide scripting to end users.
// The ray tracer code in this file is written by Adam Burmister. It
// is available in its original form from:
//
// http://labs.flog.nz.co/raytracer/
//
// It has been modified slightly by Google to work as a standalone
// benchmark, but the all the computational code remains
// untouched. This file also contains a copy of parts of the Prototype
// JavaScript framework which is used by the ray tracer.
