In this manner a user could easily test a new idea, for example, a new jitter method, without having to write an entire ray tracer to test the new functions.<P> I have created three types of objects. The first is a set of objects required in the ray-tracing paradigm. The second set is a group of objects which support the implementation of this framework. Finally, the third set is the objects used in my particular test data.<P> These objects are just for the sampling of the data. I have created an application which produces a PPM file format based on a single sample per pixel.<P></BLOCKQUOTE><I><A HREF="aindex.html"> alphabetic index</A></I> <I><A HREF="HIER.html"> hierarchy of classes</A></I><P><hr><A HREF="raytrace.tar.gz">source code</a><hr><ADDRESS>Isaac A.
