Thomas gave you the challenge: "What I want in return is you to execute and time Dr. Harrop's original code, posting the results to this thread... By Dr. Harrop's original code, I specifically mean the code he posted to this thread. I've pasted it below for clarity.". Thomas even quoted my code verbatim to make his requirements totally unambiguous. Note the parameters [9, 512, 4] in the last line that he and I both gave: AbsoluteTiming[Export["image.pgm", [EMAIL PROTECTED]@Main[9, 512, 4]]] You have not posted timings of that, let alone optimized it.

That is not my code! Look at the last line where you define the scene: Timing[Export["image.pgm",[EMAIL PROTECTED],100,4.]]] Those are not the parameters I gave you. Your program is running faster because you changed the scene from over 80,000 spheres to only 5 spheres. Look at your output image: it is completely wrong! > As i said, now pay me $300, i will then make your Mathematica code in > the same level of speed as your OCmal.

Your money back guarantee is worthless if you cannot even tell when you have failed. > Show me your OCmal code that will compile on my machine (PPC Mac, OSX > 10.4.x). The code is still on our site: http://www.ffconsultancy.com/languages/ray_tracer/ OCaml, C++ and Scheme all take ~4s to ray trace the same scene. > I'll make your Mathematica code in the same speed level as > your OCmal code.

You have not even made it 10% faster, let alone 70,000x faster. Either provide the goods or swallow the fact that you have been wrong all along. -- Dr Jon D Harrop, Flying Frog Consultancy Ltd. http://www.ffconsultancy.com/?u -- http://mail.python.org/mailman/listinfo/python-list
