C-Ray Simple Raytracing Tests

C-Ray is a simple raytracer written by John Tsiombikas; in his
own words, it is:

  "...an extremely small program I did one day to figure out how
  would the simplest raytracer program look like in the least
  amount of code lines."

The relevant discussion on Nekochan is at:

  http://forums.nekochan.net/viewtopic.php?f=3&t=15719

The default data set is very small, so C-ray really only tests the pure
floating-point (fp) speed of a CPU core (or multiple CPUs/cores using the
threaded version), ie. RAM speed is not a significant factor. John said:

  "This thing only measures 'floating point CPU performance' and
  nothing more, and it's good that nothing else affects the results.
  A real rendering program/scene would be still CPU-limited meaning
  that by far the major part of the time spent would be CPU time in
  the fpu, but it would have more overhead for disk I/O, shader
  parsing, more strain for the memory bandwidth, and various other
  things. So it's a good approximation being a renderer itself, but
  it's definitely not representative."

Nevertheless, the results are certainly interesting:

If you wish to submit your own results, follow the instructions given
below. Send the data to me, not to John, and I will add them to the
relevant tables; please include all requested details.

Comments and feedback welcome!

Ian.
